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...

Dark Matter and Stars
Under the assumption that Dark Matter (DM) is composed of Weakly Interacting Massive Particles (WIMPs), it can affect the properties of stars. In the local Universe effects are feeble, nonetheless they can in principle be used in order to pose constraints on the nature of DM particles with observations of the Sun, and of compact objects at the Galactic Center, in Globular Clusters and in White Dwarf Galaxies. The first generation of stars to...

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...

The connection between missing stellar cusps in galactic nuclei and general relativity
One of the most interesting sources of gravitational waves is the inspiral of compact objects on to a massive black hole (MBH), commonly referred to as an extreme-mass ratio inspiral. The small object, typically a stellar black hole, emits significant amounts of GW along each orbit in the detector bandwidth. On the other hand, recent observations of the Galactic center revealed a dearth of giant stars inside the inner parsec relative to the...

The dirty side of astronomy: carbonaceous dust
Since the beginning of modern astronomy, dust has always been considered an obstacle on the path to understanding both nearby and far away phenomena. 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...

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).

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....

A new sample of faint blazars
The available blazar samples were selected at relatively high limiting flux densities in the radio and X-ray band. Those samples have small sizes (30-50 objects) making it difficult to statistically derive parameters related to beaming effects. Moreover, the estimate of those parameters is based on bright and intrinsically luminous sources. A deeper, larger sample of blazars has been constructed by Perlman et al. (1998) and by Landt et al.

An Initial Mass Function for Individual Stars in Galactic Disks
The Initial Mass Function (IMF) has been derived by a variety of methods. Here we propose an IMF form (a Smoothed Two-Power Law psi_STPL) that approaches a power law at both low stellar masses (psi_STPL ~ m^(gamma)) and at high stellar masses (psi_STPL ~ m^(-Gamma)) with a turnover near the characteristic mass m_ch. The values of gamma and m_ch are derived from two integral constraints: i) the ratio of the number density of stars in the range m=...

¿Para qué (me) puede servir un GRID (del CSIC)?
Desde hace unos años se está creando a nivel europeo una infraestructura de computación distribuida geográficamente (GRID). Este GRID permite solucionar problemas computacionalmente costosos o masivos y potencia la colaboración de científicos de diferentes lugares, ofreciendo las ventajas de un sistema distribuido frente a un sistema centralizado como los supercomputadores. El CSIC participa en esta...

PLATO: The exoplanetary system explorer
I present a general overview of the PLAnetary Transits and Oscillations of stars (PLATO) space mission. PLATO was recently approved by ESA’s Science Programme Committee, together with Euclid and Solar Orbiter missions, to enter the so-called definition phase, i.e. the step required before the final decision is taken (only two missions will be implemented). To be launched in 2018, PLATO is a third generation mission, which will take...

The IAA cosmic dust laboratory
Dust particles exist in a wide variety of scenarios ranging from the Earth's atmosphere to other planetary and cometary atmospheres in the Solar System, interplanetary medium, reflection nebulae, circumstellar disks, etc. Those dust particles play an important role in the radiative balance of the body under study. Light scattering properties of spherical particles can be easily computed from Lorenz-Mie theory. However, in the majority of the...

Molecular Gas and Star Formation in Local Early-Type Galaxies
The molecular gas content of local early-type galaxies is constrained and discussed in relation to their evolution. First, as part of the Atlas3D survey, we present the first complete, large (>250 objects), volume-limited survey of molecular gas in normal local early-type galaxies, obtained with the IRAM 30m telescope. In particular, we find a surprisingly high detection rate of 23%, independent of mass and environment, but dependent on the...

MODELADO DE GALAXIAS CON ESPECTRO DE LINEAS DE EMISIÓN DEBIDO A FORMACIÓN ESTELAR
Generalmente se asume que el espectro de líneas de emisión de galaxias con formación estelar se puede modelizar mediante una única región HII. En este trabajo investigamos cuándo dicha aproximación es adecuada y cuándo el modelado se debe realizar mediante la emisión de un conjunto de diferentes regiones HII ionizadas por cúmulos de diversos tamaños. Con este fin...

Stellar cusps in gallactic nuclei
We will give a brief introduction into stellar cusps in Galactic nuclei or, more in general, around massive black holes. We will treat topics such as: What is a stellar cusp? How does it form? What does the presence or absence of a stellar cusp tell us about a galactic nucleus? Is there a stellar cusp around the black hole at the center of the Milky Way?

ALMA/CASA: You better get ready for them!
ALMA is going to start its Early Science Observations during 2011 and a Call for Early Science with its compact array will be issued at the end of this year. At the same time, CASA, the software that ALMA users will have at their disposal, is being continuously developed. I will present an overview of a couple of workshops I attended in Manchester related to ALMA and CASA, which hopefully will encourage you to think for proposals with ALMA and...

La PPN M 2-56: rápida evolución nebular gobernada por múltiples eyecciones post-AGB
La etapa de Nebulosa Protoplanetaria (PPNe) o post-AGB comienza cuando las estrellas, con masas en la Secuencia Principal (SP) entre 0.6-8 masas solares, abandonan la Rama Asintótica de las Gigantes (AGB) y termina cuando alcanzan la fase de Nebulosa Planetaria (PNe). La duración de esta etapa de la evolución estelar es muy breve, de ~1000 años, sin embargo en ella se producen cambios radicales que afectan tanto a...

Unfolding Properties of Mass Loss at the Tip of the Asymptotic Giant Branch
In the final stages of stellar evolution low- to intermediate-mass stars lose their envelope in increasingly massive stellar winds. Matter, which has been processed inside these stars, is thereby returned to the interstellar medium, and mass loss also determines properties of subsequent planetary nebulae. In order to obtain properties of winds at the tip of the asymptotic giant branch we observed weak halos of a set of planetary nebulae in the...

El arco iris como medidor de distancias cosmológicas.
Comenzando con una breve introducción histórica, me gustaría aprovechar esta sesión CCD para presentaros, de una forma sencilla, qué son, por qué surgen, para qué se utilizan y por qué se han convertido en una herramienta tan importante los famosos “photometric redshifts”, en el marco de la cosmología moderna. Curvaturas, geometrías, dilataciones espacio­...

OCTOCAM: A fast multichannel camera and spectrograph for the 10.4m GTC
OCTOCAM is a high time-resolution multi-channel instrument that is being proposed for the 10.4m GTC telescope. It will perform simultaneous observations in 8 bands, covering the complete spectrum from the ultraviolet (u-band) to the near infrared (K-band) in a single exposure. An imaging mode will allow to observe a field of 2'x2' in all ugrizJHK bands, with the possibility to observe at time resolutions of up to 10 ms, while the spectroscopic...

Size matters
This is a talk I gave last October in Freiburg as the opening key-note lecture of the "1st EAST-ATST Workshop". The American ATST (Advanced Technology Solar Telescope) and the European EST (European Solar Telescope) are projects for designing and building the new generation of large-aperture, solar telescopes. Both of the 4-m class constitute a technological breakthrough and promise a significant step forward in our understanding of...

Structure and kinematics of the Milky Way's nuclear star cluster
The Galactic center is a unique target for studying the properties of the nuclei of galaxies in general. The supermassive black hole, Sagittarius A*, that is located at the dynamical center of the Milky Way is surrounded by the densest and most massive star cluster of our Galaxy. In this talk I will focus on the most recent results of research on the structure and kinematics of the Milky Way's nuclear star cluster. Adaptive optics imaging is a...

Testing spectral models for Stellar Populations
High spectral resolution evolutionary synthesis models have become a routinely used ingredient in extragalactic work, and as such deserve thorough testing. Star clusters are ideal laboratories for such tests. In this talk I apply the spectral fitting methodology to a sample of clusters, mainly from the Magellanic Clouds and spanning a wide range in age and metallicity, fitting their integrated light spectra with a suite of modern evolutionary...

e-Ciencia de la A a la Z
Al hablar de e-Ciencia es complicado no mencionar los Grids. Al hablar de Grid es fácil relacionar con computación. Pero podemos ampliar este concepto pues, al fin y al cabo, un Grid viene a ser una malla que conecta cosas. Estas cosas están distribuidas geográficamente e interconectadas en red. De esta forma podemos tener no solo Grids de computación, sino también de datos o instrumentos, e incluso...

Pulsating stars harbouring planets
In this talk, I present a review of the current status of the very recent line of research linking stellar seismology and exoplanet search. I give a summary of the main exoplanet searching techniques and a general overview of stellar seismology. Some examples of the synergies between these two lines will also be given. If a star harbouring planets is found to be pulsating, our knowledge of the physical characteristics of these planets is...

Extragalactic research with the Virtual Observatory
Nowadays, following years of technological development, Virtual Observatory standards, resources, and services became powerful enough to help astronomers making real science on everyday basis. An astronomer is able to combine ``online'' VO-enabled parts with ``offline'' research stages including dedicated data processing and analysis, observations, numerical simulations. I will present three VO-science projects combining VO and non-VO blocks,...

Observational constrains to galaxy evolution from the distribution of integrated stellar ages and metallicities in spiral galaxies
I will present new results on the integrated stellar populations of bulges, bars and disks of spiral galaxies from long-slit spectroscopic observations. We have derived the ages and metallicities using both the whole spectra and stellar line-strength indices along the bar and bulges for a sample of 20 disk galaxies and derived the populations in the disks of four galaxies using GEMINI spectroscopic data. We find, in the distribution of stellar...

The First 3mm Polarimetric Survey of Radio Loud AGN
Relativistic jets in AGN are the most energetic and among the most powerful astrophysical objects known so far. Their relativistic nature provides them the ability to emit profusely in all spectral ranges from radio wavelengths to TeV gamma-rays, as well as abrupt variability in all time scales (from hours to years). After an extended review of the present knowledge of these objects, but paying particular attention to blazars, the main results...
