Spatially resolved star formation history of CALIFA galaxies: Implications for galaxy formation
One year after the final data release of the CALIFA survey, I will revise the results obtained from the analysis of the spatially resolved stellar population properties of galaxies and their impact on our knowledge on galaxy formation and their evolution. I will do special emphasis in the more recent results on the spatially resolved star formation histories of galaxies obtained for our group at the IAA. I will show, in my opinion, the...

Fractal analysis in pulsating stars: what is and what we can learn from it
I will describe the basic ideas of my line of research, concerning the develop of classification criteria and algorithms for the identification of delta Scuti, gamma Doradus and Solar-like pulsating stars, based on chaos analysis and multi-fractal analysis. In fact multi-fractal behaviour in light curves, which emerges at the onset of chaos, could be the fingerprint of the stochastic mechanism of modes excitation, due to an outer convective...

The large abundance discrepancy phenomenon in planetary nebulae
The discrepancy between chemical abundances computed using optical recombination lines (ORLs) and collisionally excited lines (CELs) is a major unresolved problem in nebular astrophysics, with significant implications for the determination of chemical abundances throughout the Universe. In planetary nebulae (PNe), a common explanation of this discrepancy is that two different gas phases coexist: a hot component with standard metallicity, and a...

Galaxias activas: unas tanto y otras tan poco
Muchas galaxias del universo, incluida nuestra propia Vía Láctea, contienen en sus centros agujeros negros supermasivos (de entre unos pocos millones hasta miles de millones de veces la masa del sol). Pero en solo una pequeña fracción de esas galaxias, las llamadas “galaxias activas”, se activan en sus núcleos una serie de mecanismos que pueden llegar a ser muy violentos.

Detection of gravitational waves from space: the LISA mission
The idea of detecting gravitational waves from space has been under consideration for more than 25 years. In 2012, the advisory bodies of ESA decided that the next-but-one "large mission", L3, will be devoted to this. Launch is scheduled for 2034. In 2015, the Director of Science of ESA appointed an external committee, with Michael Perryman as chair, to advise on the technical feasibility of the LISA mission, and the technology development...

Star formation in nearby early-type galaxies
It is well known that there is little star formation activity in early-type galaxies. By cross-matching SDSS DR 7 with RC3 catalog and visually checking the SDSS images, we derive a sample of 583 S0 galaxies with the central spectrophotometric information. In order to separate nebular emission lines from the underlying stellar contribution, we fit the stellar population model to the SDSS spectra of these S0 galaxies. According to the BPT diagram...

Supermassive Black Holes: Impact on Galaxy Formation and Evolution
Supermassive black holes, weighing between millions to billions times the mass of the Sun, are believed to power quasars and other energetic activity in the centers of galaxies. With the help of advanced telescopes from the ground and in space, operating across the electromagnetic spectrum, astronomers have now discovered that supermassive black holes not only exist, but that they are very common and play a critical role in the formation and...

Recovering information beyond the power spectrum of large-scale structure
Future galaxy surveys of the large-scale structure in the Universe will provide a wealth of new data and make it possible to use higher-order statistics beyond the power spectrum, such as the bispectrum (or 3-point correlation function), to constrain galaxy clustering, the standard LCDM cosmology, and many of its possible extensions. However, it may be possible and preferable to use recently devised alternative statistics, such as the line...

The impact of environment and confusion of the observed HI galaxy population
The HI galaxy mass function represents a fundamental component of our understanding of the gas content of galaxies. How its form varies throughout the local Universe and as a function of redshift is key to developing a complete picture of galaxy evolution. We use the ALFALFA 70% catalogue, the largest uniform catalogue of extragalactic HI sources to date, to explore the environmental dependence of the HI mass function based on the projected...

Molecular gas and dust in low-metallicity starbursts
Metal-poor, star-forming, dwarf galaxies play a fundamental role in galaxy formation and evolution, and according to LambdaCDM models may be the building blocks of most of the galaxies in the universe today. Although the interstellar medium (ISM) in such galaxies was thought to be virtually dust-free, over the last decade, observations have shown that dust can be an important constituent of even a low-metallicity ISM. However, the molecular...

Cold plasma and magnetic reconnection at the magnetopause boundary layer
Magnetic reconnection is a fundamental plasma process that permits the exchange of energy and mass between colliding plasmas, e.g., between the Solar Wind and the Earth's magnetosphere. Several studies have reported the presence of cold plasma of ionospheric origin at the magnetospheric side of the magnetopause boundary layer. As a result, the particle distribution functions involved in reconnection are far from equilibrium, exhibiting a cold...

Living on the Edge: Superthin Galaxies and the Cosmic UV Background
Superthin galaxies are bulgeless, late-type spiral galaxies seen edge-on. HI synthesis observations probe the kinematic structure of their interstellar medium. Observations of these isolated, quiescent galaxies have reached column densities as low as few x 1018 atoms . cm-2 . The simple structure of the superthins makes them ideal cosmological laboratories (Uson and Matthews, Astron. J. 125, 2455, 2003). I shall present the results of high-...

Asteroid surfaces: irradiation and VIS-IR micro-spectroscopy in the laboratory
Primitive extraterrestrial materials, such as meteorites and dust collected by sample return missions, are characterized by a large compositional heterogeneity at different scales. This heterogeneity has been observed in the laboratory by different techniques. Among these, micro-IR spectroscopy has the advantage of being totally non-destructive and allowing direct comparison with astronomical observations. With the development of Focal Plan...

Novae as Lithium factories in the Milky Way
The abundance of Lithium observed in very young stellar populations is ~4 times larger than the primordial one estimated by recent Planck measurements. Since Lithium is easily destroyed in stellar interiors, the search for astrophysical sources responsible for of the observed Lithium over-abundance was a mystery for decades. In this seminar I'll discuss the recent detection of Lithium in the spectra of two slow novae, V1369 Cen and V5668 Sgr,...

Witnessing the birth of a planetary nebula
Planetary nebulae are one of the last stages of evolution of stars like our Sun. The beginning of photoionization, giving rise to a new planetary nebula, will certainly produce dramatic changes in the object, but this instant is difficult to observe, since it will only take a few decades. During of a long-time study of water masers in post-AGB stars and planetary nebulae, we identified an object (IRAS 15103-5754) in which we believe...

Multiwavelength analysis of PBC J2333.9-2343
Nuclear activity as is observed in active galactic nuclei (AGN) might be a phase occurring in all galaxies, and this activity could be recurrent. A perfect laboratory to test these scenarios are the giant radio galaxies, since their emission can be as old as 10⁷-10⁸ years. In the present work we focus on the nucleus of PBC J2333.9-2343, which called our attention because it is a giant radio galaxy that shows different and incompatible...

The CaII triplet in Quasars: from the accretion disk to the star formation
Active galactic nuclei (AGN) show a great diversity of optical and UV emission line properties. Dynamical and physical models should be built accordingly.

Shaking the grounds of unification: are type 1 and type 2 AGN intrinsically different?
The simplest standard unified models of Active Galactic Nuclei (AGN), put forward more than 30 years ago, postulate that the diversity of observed properties of AGN can be largely explained as a viewing angle effect resulting in anisotropic nuclear obscuration. A key ingredient of these models is a homogeneous distribution of dust and gas located at tens of parsecs that obscures the AGN nuclear region from certain lines-of-sight (the ‘torus’)....

Challenges of the Doppler technique in the presence of stellar noise for the detection of Earth-like exoplanets
The Doppler method is still the most efficient one in detecting exoplanets around nearby stars which are amenable for further characterization. In particular, planets as small as the Earth can in principle be detected in hot orbits around sun-like stars (G and K dwarfs), and warm to temperate orbits around M-dwarfs (M<0.5 sun) in orbital periods from a few days to tens of days. Unfortunately, these time-scales are plagued with structured...

Marte: emisiones de metano, de agua y de noticias
En los últimos 12 meses se han acumulado varias noticias científicas sobre Marte de gran impacto y en cierta medida inesperadas, como el (re)descubrimiento de metano en su atmósfera, y la muy probable existencia de agua fundida en el subsuelo. Además se han sucedido propuestas pseudocientíficas como Mars One y el estreno de la esperada película "Marte" (The Martian), vestidas ambas de un aparente realismo científico.

Following the posterior with the ALHAMBRA survey
The probability distribution functions (PDFs) provided by photometric redshift codes such as BPZ are a powerful tool for galaxy evolution studies. Despite of their potential, only a few studies in the literature attempt to use the full PDFs in their analysis and we are still learning how to make the most of them. We present the latests PDF advances from the ALHAMBRA survey, focusing in the estimation of the B-band luminosity function. We...

High Spatial Resolution 2D Nebular Abundances in Disk Galaxies
Galaxies evolve through the changes that face their various components such as the gas, dust, stars, and dark matter. Gas and dust are prime ingredients for the formation of new stars, and thereafter the massive stars newly formed will quickly modify the chemical composition of galaxies whereas low mass stars will take more time to contribute to the interstellar gas enrichment. Beside the stars, other processes occurring during the galaxies...

Color y vida
¿Qué es el color? ¿Cómo se produce el color en la naturaleza? ¿Cómo usan el color los seres vivos? Veremos qué es y cómo se percibe el color: un poco de física, química, anatomía, fisiología, neurología y psicología son necesarias para entender cabalmente el color.

Dissecting a rare galaxy merger (the Hummingbird) with radio and mm-observations
The Bird is a luminous infrared galaxy product of a triple merger. Previous infrared observations have shown that the ongoing star formation in the least massive of the components (the head) outshines that of the mprimary nuclei (the heart and the body). This clashes with the commonly accepted major merger scenario in which the SF is expected to be higher in central compact regions. Here I will present preliminary results...

Test In Space, your opportunity to experiment in orbit
Traditionally, experimentation in space has consisted in limited, expensive, long-term and complicated projects with hard requirements and restrictions. Currently, new space increases the possibilities to experiment in space for researchers from all kind of fields and, with TEST IN SPACE, this is also simple and fast. If you are interested in investigation under real space environment, you can just propose it to TEST IN SPACE. TEST IN SPACE...

Baryon Acoustic Oscillations and the Expansion History of the Universe
The tiny inhomogeneities left over from the inflationary phase seeded the early Universe with primordial density perturbations. The photon-baryon fluid reacted to these perturbations by forming spherical pressure waves known as baryon acoustic oscillations (BAO). These waves propagated through the primordial plasma until the Universe became transparent to radiation, effectively stopping the dragging of the baryons by the photons. This left...

Untold Stories of Andromeda: A Multi-wavelength View of The Nuclear Environment in M31
The Andromeda galaxy (M31), which harbors the nearest LINER and the closest stellar bulge accessible in the optical, is an ideal laboratory for studying the physical regulation of galactic nuclei, and in turn the co-evolution of super-massive black holes and their host galaxies. I will provide an overview of the stellar and interstellar components of the M31 bulge, as well as its dormant but otherwise well-known SMBH, M31*. I will introduce...

Autoorganización, propiedades emergentes y algoritmos genéticos
La naturaleza tiene una forma muy eficaz de producir individuos capaces de adaptarse a ambientes cambiantes y de resolver problemas complejos. En esta charla hablaremos de como podemos inspirarnos en esto para realizar algoritmos que resuelvan tareas que de otro modo serían imposibles, y por el contrario, también veremos como con reglas muy sencillas podernos replicar el comportamiento de sistema muy complejos.

Into Darkness: the seek for pulsars in the Galactic Centre
Pulsars are highly-magnetized rotating neutron stars that emit beams of electromagnetic emission. They are unique astronomical laboratories, not only because they are the most magnetized, densest, directly-observable objects in the Universe, but also because they act as extremely precise clocks located all over the Galaxy. The variety of science enabled by pulsars is very broad, from, e.g., limits on the Equation-of-...

The influence of dynamics on airglow and constituents in the terrestrial mesopause region
In the terrestrial atmosphere, the mesopause region (~90 km height) is a transition region between the inviscid lower/middle atmosphere and the geomagnetically forced geospace. It is a region of strong dynamical forcing and where several constituents vary strongly with height one of which is atomic oxygen. Airglow, which is the result of naturally occurring chemiluminescence in the mesopause region involving exothermic reactions associated...

Ubiquitous magnetic flux emergence in the Sun: a fundamental process
The fundamental process of magnetic flux emergence happens continuously and everywhere over the solar surface, hence the ubiquitousness. No matter which spatial (granular, supergranular, active region) and temporal scale we look at buoyant magnetic field coming from the convection zone pierces the photosphere in the form of two opposite polarities and travels upwards through the solar atmosphere. We will describe the general characteristics...

Massive Star Formation at the Puerto Varas Workshop
The recent decades have witnessed major advances in our understanding of the formation of solar-mass stars. However, the formation mechanisms of stars at the extremes  of the mass range, that is, on one hand very massive stars and in the other brown dwarfs, remain poorly understood. I will summarize the main results presented in a recent meeting on massive star formation that took place in Puerto Varas,...
