Space VLBI observations with RadioAstron provide an extraordinary improvement of angular resolution. In this talk, I will present the results obtained from RadioAstron imaging of the relativistic jet in the quasar 0836+710 at L, C, and K bands.

I shall comment on the difficulties faced today by the so called "Unified Model" (UM) for AGN. According to this model,  type1 and type 2 AGN are the same except for a combined effect of orientation and obscuration in the line of sight.

The first phases of galaxy formation and evolution remain poorly understood and improved observational constraints are needed to test the theoretical picture and simulations.

HETH is one of the youngest groups at IAA, founded in 2012, and belongs to both the extragalactic and stellar department. Thanks to recent success in funding applications, both by the group and by external researchers, HETH has now grown to a group of 7 young researchers.

This august, we have published clear evidence of a planet orbiting the nearest star to Earth, Proxima Centauri, at a distance of 1.295 parsecs (4.2 ly) and one of the best-studied low-mass star.

CALIFA (Calar Alto Legacy Integral Field Area survey) has provided spatially resolved optical spectra of thousands of HII regions in spiral galaxies of the Local Universe whose properties can be linked with the integrated properties of the host galaxies.

In this talk I present an analysis of the gas-phase oxygen abundances of a sample of 28 galaxies in the local Universe (z<0.02) hosting Type Ia Supernovae (SNe Ia). The data were obtained with the 4.2m William Herschel Telescope (WHT).

The RadioAstron Space VLBI mission utilizes the 10-m radio telescope on-board the dedicated Spektr-R spacecraft to observe cosmic radio sources with an unprecedented angular resolution at 92, 18, 6 and 1.3 cm. The longest baseline of the space-ground interferometer is about 350,000 km.

Blazars are the most luminous persistent objects in the sky. They emit light across the entire electromagnetic spectrum, from low-energy radio waves to high-energy gamma-rays, and they exhibit variability on timescales that range from years down to minutes.

In this talk I will focus on the most luminous LINERs in the local universe, where we studied their SF and AGN activity in order to understand the LINER phenomenon in relation to star-forming galaxies and to compare their properties with those of the LINERs at z ~ 0.3.

The solar chromosphere is permeated by solar structures such as sunspots, surges, flare ribbons, prominences (filaments) or spicules, where non-local thermodynamic equilibrium effects dominate the state of the plasma and where the magnetic fields are expected to be much lower in intensity than in

Almost every massive galaxy has at least one super-massive black hole (SMBH) at its center. Most (>90%) of those SMBHs are quiet. Understanding the accretion of low-luminosity SMBHs represents a very important and fundamental problem in astronomy.

La formación, evolución y muerte de las estrellas es, quizás, el núcleo esencial de la astronomía.

The standard view is that black holes exist, maybe not with all the properties of strict black holes in classical General Relativity, but sufficiently close to them that one does not need worrying in the astrophysical practice.

Funded by an ERC Consolidator grant, eLightning is a research project about one of the most familiar but also least understood phenomena in nature: the lightning discharge.

The upper mass stellar initial mass function is similar to the mass function of young star clusters.  I argue that this is a basic result expected when gravitational focusing on scales much larger than the Jeans length operate.

Brown dwarfs are the objects that bridge the realms of stars and planets, making them important benchmarks for testing star and planet formation theories.
