Development of a miniaturized real time attitude controller for micro and nanosatellites
In last years low cost space missions have become an instrument for many research institutes to test new technologies and perform low-orbit Earth science using commercial components. Cubesat represent the most popular standard for microsatellites, but due to low cost components and reduced size, there are no complete attitude controllers available for the smallest versions. This talk will describe the development of a control system...

Ice Rocks in the Solar System
The study of the minor bodies in the Solar System has historically been a major source of information. The term "Minor Body" covers objects exhibiting very different dynamical and compositional characteristics, in fact, every object in the Solar System that is not a planet or a star, is a minor body. All these objects share a common link, they were the building blocks of the Solar System that we observe today and are considered to...

The thirteen billion year history of the most massive black holes
Super-massive black holes (BHs) that are found in the centers of most galaxies started their growth when the universe was about 300 million years old. Some of these "seed black holes" were probably the remnants of the earliest stars. The largest BHs, that are some 10^10 times more massive than the sun, accumulated most of their mass during the first 3 billion years after the big bang. The less massive ones are still growing today. I...

Detecting substructure in the galactic stellar halo with Gaia
We present a Gaia mock catalogue we have created to test various approaches to detect the presence of past mergers in the Galactic halo. We propose an extension of the great circle cell method of Johnston et al. (1996), which is optimized to identify tidal debris along great circles in the sky. We have added the proper motion information that will be supplied by Gaia to add a kinematical restriction to the original method. We test our...

What can we learn from gamma-ray anisotropies?
Over the last two decades the study of angular anisotropies provided a huge amount of information, when used to analyze the Cosmic Microwave Radiation. The same approach can be extended also to higher energies, studying angular fluctuations in the gamma-ray emission. In this talk I will refer in particular to the data of the Fermi-LAT telescope that has recently presented its measurement of the angular power spectrum (APS) of anisotropies at...

Seeking and Mocking Non-thermal Emission in Galaxy Clusters
Diffuse synchrotron radio emission is observed in many clusters of galaxies probing the presence of high energy cosmic ray (CR) electrons. This emission can be explained by the hadronic model where the electron population originates from the interactions between CR protons and the cluster ambient gas. Additionally, a very high energy gamma-ray emission is also expected. I will briefly review the current knowledge on the non-thermal emission...

Mundo amigo, Mundo Cruel
Hace cerca de 4.500 millones de años, el planeta Tierra se formó a partir del material que quedaba alrededor del Sol. Fue el comienzo de un largo, violento y caótico periodo en el que se configuraron la corteza terrestre, los océanos, la atmósfera y todos los elementos que conforman el paisaje terrestre que hoy conocemos. Teniendo en cuenta que durante este proceso también se crearon las condiciones óptimas para el desarrollo de la vida, no...

Maser emission in evolved stars: from AGB to PNe
I will present a review of maser emission in evolved stars from the asymptotic giant branch (AGB) to planetary nebulae (PNe). The circumstellar envelopes of oxygen-rich evolved stars provide optimal conditions to pump different species of masers, emitting at radio wavelengths. Interferometric observations of masers are a powerful tool to study with the highest angular resolution the molecular gas around evolved stars, because...

Dwarf galaxies as dark matter laboratories
Dwarf spheroidal galaxies are key objects in the current cosmological paradigm: first, they are the least luminous galaxies, likely signaling the minimum halo mass at which gas can be accreted and converted into stars. Second, they all have ancient stellar populations, providing clues on star formation/feedback processes at early stages of the Universe. Third, they are the most numerous satellites about the Milky Way and M31,...

Albedo and atmospheric constraints of dwarf planet Makemake from a stellar occultation
Makemake is an icy dwarf planet with a spectrum similar to Eris and Pluto, and is currently at a distance to the Sun intermediate between the two. Although Makemake’s size (1,420 ± 60 km) and albedo are roughly known, there has been no constraint on its density and there were expectations that it could have a Pluto-like atmosphere. Here we report the results from a stellar occultation by Makemake on 2011...

Dynamical Modeling of Luminous Infrared Galaxy Mergers
It is widely accepted that galaxy mergers can have a significant effect on galaxy properties and may be an important part of galaxy evolution. Enhanced star formation is one frequently observed property of (gas rich) mergers and theoretical prescriptions for star formation can generally reproduce the observed behavior. However a detailed study comparison of these prescriptions with individual galaxy merger events has not been...

Mass, metallicity and SFR relationships in star forming galaxies using deep surveys
To understand the formation and evolution of galaxies, it is important to have a full comprehension of the role played by Metallicity, Star Formation Rate (SFR), and stellar mass of galaxies. The interplay of these parameters at different redshifts will substantially affect the evolution of galaxies and, as a consequence, the evolution of these parameters provides important constraints for the galaxy evolution models. We studied the...

Revealing the hidden supernova population in luminous infrared galaxies
A substantial fraction of star formation (SF) and hence of the core-collapse supernovae (CCSNe) in the Universe is hidden behind dust. At higher-z obscured star formation in luminous and ultraluminous infrared galaxies (LIRGs and ULIRGs) actually dominates over SF seen in the UV and optical. These same objects are expected to hide in their nuclear regions large numbers of undetected CCSNe. In this talk I describe our ongoing efforts using...

Gamma-Ray-Bursts, High-Energy-Cosmic-Rays and Beam-Plasma Instabilities
Gamma-Ray-Bursts and High-Energy-Cosmic-Rays are two of the most intriguing enigmas of astrophysics. A promising scenario solving both problems consists in the Fermi-like acceleration of particles by relativistic collisionless shocks. These shocks could generate the Gamma Burst together with some highly energetic cosmic rays, in the earlier phase of a Supernovae explosion. Later on, the  Supernovae Remnant could still accelerate cosmic...

Locating the gamma-ray emission region in AGN from multi-messenger observations
Relativistic jets in AGN, in general, and in blazars, in particular, are among the most energetic and powerful astrophysical phenomena known so far. Their relativistic nature provides them with the ability to emit profusely at all spectral ranges from radio wavelengths to gamma-rays. They display extreme variability at all time scales (from hours to years). Since the birth of gamma-ray astronomy, locating the origin of gamma-ray emission has...

Mapping star-formation in the Milky Way
In the last few years, it has become possible to measure the distance and the velocity vector of young stars located within 500 pc of the Sun with an accuracy of order 1% using Very Long Baseline Interferometry (VLBI) techniques. This represents an improvement by more than 1 order of magnitude over what was previously possible, and opens the door to some extremely high accuracy astrophysics. In particular, theoretical pre-main sequence...

Early r-process enrichment in the halo: Process and implications/The future role of the Nordic Optical Telescope

The now appreciable sample of extremely metal-poor (EMP) stars with [Fe/H] ~ -3 trace the transition to this chemically more diversified regime. A small fraction of these EMP giants contain r-process...

Early Planet Formation from an Experimentalist’s Point of View
Planet formation starts in gaseous protoplanetary disks. Small grains move around, collide, stick together and grow. However, many collisional roads also lead to destruction of larger bodies. Which ones are prevailing and if this is the basic way to planet formation is still an open question, but there are modes to grow particles to larger size even in ‘high speed’ collisions. This talk will also touch upon processes of transport...

Coagulation, restructuring and fragmentation of dust grains in the protoplanetary disks: first stages of Solar System formation
The understanding of the formation of the planetary systems is one of the main topics of modern astrophysics and its study requires a synergetic effort of observations, laboratory experiments and theoretical models. It is generally accepted that planets originate in the dust disk that remains around a star after its formation (protoplanetary disk). Nevertheless there are no clear ideas on the physical conditions that are required, neither on...

Quasi-periodicities in the periodograms of Corot Delta Scuti stars
Periodic patterns are not expected to be found in the frequency spectra of delta-Scuti stars, as in solar-like pulsators. However, some efforts have been carried out in order to find any signal of periodicity in this type of stars (Handler et al., 1997; Breger et al., 1999, 2009). These works used ground-base observations and the results have not been conclusive. In our study we have used data from CoRoT of two delta-Scuti stars poorly known. We...

Coronal heating on the Sun: new observations and “realistic” 3D numerical models
The heating of the solar corona is a long standing problem of solar physics, in fact dating back to the time when it was first discovered that the corona was quite hot. In short, the question is how one can find a credible physical mechanism to transport and dissipate a small fraction of the “mechanical” energy contained in the convection zone in(to) the corona. Amusingly, most answers to the question date back to the late 1940...

Gamma-ray Bursts - what kind of stars do they come from?
Long GRBs are the most luminous objects in the universe and mark the collapse of a very massive star, usually accompanied by a relativistic supernova. Their large distances do not allow us to directly identify the progenitor star as we were able to do with some type of supernova. We therefore rely on indirect methods to derive some information on the kind of progenitor star or system and what makes a massive star to explode in a supernova or...

On the other hand, recent observations of the Galactic center revealed a dearth of giant stars inside the inner parsec relative to the...

In this talk I will explain briefly the origin and the life-cycle of carbonaceous dust, introduce to new discoveries and old puzzles and eventually show how dust can be used as a powerful astronomical tool.

Analysis of chemical and dynamical processes in the Earth's Atmosphere with MIPAS data
MIPAS is a Fourier transform limb emission mid-infrared spectrometer in Earth orbit. It provides spectrally resolved radiance profiles in the 4.15 to 14.6 mum spectral region from about 5 km up to 70 km (in its nominal mode) and up to 150 km in special observation modes. At IMK and IAA, we retrieve temperature and the distributions of up to 30 trace species from these data, which then are used to study chemistry and dynamics of the atmosphere...

Star formation at high-z: a stacking approach applied to mm-data
Star formation is a key ingredient of the formation and evolution of galaxies. The associated dust emission has been observed up to very high-z. At mm wavelengths, this can be done thanks to the negative k-correction, which compensates the increasing luminosity distance. However, only the brightest sources can be detected with the present instruments, even with the early ALMA capabilities. Here we present a routine to perform stacking analysis...

A 2D Spectroscopy view of NGC 588
Most of today's stars were formed in high intensity episodes about 7-10 Gyr ago. However, at these redshifts both resolution and dimming effects make it difficult to study in detail the interaction of the gas, dust and newly formed stars. Giant H II regions in very nearby galaxies constitute their best local counterpart to address such a study. Here, I present an analysis of NGC 588, a GHIIR in M33, based on optical Integral Field Spectroscopy...

Gravitational Wave Astronomy in the 21st Century
The discovery of the binary pulsar PSR B1913+16 by Hulse and Taylor provided definite evidence of the existence of gravitational waves as predicted by Einstein's General Theory of Relativity. It also contributed to encourage the development of different gravitational wave detectors that was pioneered in the 60s by Joseph Weber. Presently, we have a world-wide network of ground detectors that is expected to achieve the first detections during the...

The Physics and Philosophy behind Cosmic Time
How far back in time can we have knowledge of the universe? Most cosmologists would agree that the physics describing the ‘material content’ of the universe becomes increasingly speculative the further we go back in time. By contrast, it is widely assumed that the concept of time itself – by virtue of the cosmological standard model – can be safely extrapolated sixty orders of magnitude back from the present to the Planck...

A Magnetized Jet from a Massive Protostar
Supersonic jets are observed to emerge from a wide variety of astrophysical systems, from young stellar objects (YSOs) to AGNs. Despite their different physical scales (from hundreds to billions of astronomical units), they have strong morphological similarities. However, it is yet unclear whether there is a universal mechanism that can explain the origin of all these jets. Theoretical models suggest that the magnetic field is a fundamental...

The Transneptunian Region and Clues about Planet Formation
The Transneptunian belt is a reservoir of icy bodies in the outer reaches of our solar system. This region is believed to be the source of the Jupiter-Family Comets and is also thought to contain very pristine material, the leftovers of planet formation beyond the ice line. Therefore, the TransNeptunian Objects (TNOs) carry important information on how the solar system was formed, and can give plenty of details on the processes that were...

Substellar Objects in Nearby Young Clusters (SONYC): Towards an Unbiased Census
SONYC, "Substellar Objects in Nearby Young Clusters", is an ongoing project to provide a complete census of the brown dwarf and planemo (free-floating objects with masses comparable to those of massive planets)population in nearby young clusters. The SONYC survey relies on extremely deep wide-field optical and near-infrared imaging and follow-up spectroscopy. We make use of Subaru, VLT, Gemini, CTIO, NTT, and Spitzer to probe the...

CheFlet polar basis for astronomical data analysis
We present a new method to decompose galaxy images. We have developed a polar orthonormal basis, built using Chebyshev rational functions to expand the radial coordinate, and Fourier series to represent the azimuthal component. The method can fit galaxies in a very compact way, including simultaneously most of the galaxy substructure and the extended wings of the galaxy profile. Some applications of this method are being developed: photometry...

Star formation at small galactic scales
We present a study of the distribution of star, gas, and dust components in star-forming regions in nearby galaxies. The targets sample a wide range of luminosities and morphologies in order to study how the violent star formation influences the dust and gas distribution inside the star-forming regions. The analysis is based on the comparison of multi-wavelength data from theFar-Ultraviolet (GALEX) to the Infrared (SPITZER and HERSCHEL).

Sondeo de la alta atmósfera de Venus y Marte usando espectroscopía molecular en el IR
La alta atmósfera de los planetas terrestres se caracteriza, entre otros aspectos, por sus bajas densidades y condiciones ópticamente delgadas a la radiación solar en el visible/UV. La única excepción son las bandas moleculares IR en la región espectral por encima de 2um por las cuales los procesos radiativos se hacen significativos. Por tanto, las observaciones IR constituyen una herramienta ú...

El campo magnético en galaxias
El campo magnético de una galaxia no es solamente importante porque nos proporciona un método de observación, sino también por sus efectos dinámicos. En el pasado se estudió el proceso v -> B pero cada vez se reconoce más el proceso B -> v , es decir el campo magnético ha dejado de ser una magnitud pasiva para influir activamente en el movimiento. La importancia del magnetismo galáctico afecta a determinadas estructuras y también...

Stellar Population Synthesis at the End of 2010
Recent developments in stellar evolution theory describing critical phases of this process (e.g. TP-AGB), and the availability of new libraries of theoretical and empirical stellar spectra allow us to build more complete and realistic population synthesis models than those in common use. I will discuss the application of these models to various problems of interest and will review those aspects that still require some amount of theoretical and...

Dark matter on department scale
The direct detection of dark matter on Earth depends on its density and its velocity in the Solar neighbourhood. Unforunately, it is uncertain whether the dark matter distribution on the relevant physical scales (milliparsec) is homogeneous or not. Traditional N-body simulations cannot achieve the required resolution, so we have developed an ingenious method, able to achieve virtually any arbitrary resolution at almost no computational cost....
