The Cherenkov Telescope Array (CTA) will become the reference observatory for Very High Energy (VHE) Gamma Ray Astronomy during the next decades.

Si el Señor Todopoderoso me hubiese consultado, antes de embarcarse en la Creación, le habría recomendado algo más simple.

Intensity mapping surveys of neutral hydrogen (HI) are a new way to measure the large-scale matter distribution of our universe over a wide range of redshifts, and thus constrain cosmological parameters describing the universal expansion.

After several decades of studies the basic nature of nuclear activity of galaxies is well understood.

Intermediate and high-mass forming stars have a large impact on the interstellar medium and nearby star forming regions.

This lecture aims to increase researchers’ awareness of the current demands for the inclusion of sex and gender in their research.

The environment around the Sun and other late-type stars is controlled by magnetic fields.

Many stars evolve into magnetic white dwarfs, but we do not know when the magnetic field appears at their surface, if and how it evolves during the cooling phase, and, above all, what are the mechanisms that generate the field, and why they act on some but not all degenerate stars.

The classical picture to explain the observations of active galactic nuclei (AGN) required a geometrically and optically thick torus of molecular gas and dust to obscure the central engine from some lines of sight.

Despite traditional thinking, an appreciable population of (relatively small) supermassive black holes may be lurking in dwarf galaxies.

Exoplanets are expected to sustain various plasma interactions with their parent star, depending on the stellar and planetary magnetic field strengths and on the sub- or super-Alfvénic wind speed at the planet’s orbit.

A first step towards understanding planetary formation is the characterisation of the structure and evolution of protoplanetary discs.  Although the large scale disc is understood in some detail, very little is known about the inner few au.

With the Square Kilometre Array still several years away, SKA pathfinder telescopes are already enabling transformational science in radio astronomy with their astounding improvements in field-of-view, sensitivity, spatial resolution, and spectral bandwidth coverage.

Binary stars evolve into chemically-peculiar objects and are a major driver of the Galactic enrichment of heavy elements.

Lyman continuum emitters are galaxies showing escaping ionizing radiation, which thus contributes to ionizing the intergalactic medium. They may be the dominant source of cosmic reionization.

Accreting black holes emit in X-rays at the wave-band in which THESEUS will be observing (0.3 keV-20 MeV) due to their extreme physical conditions.

The central black hole of active galaxies accretes large amounts of matter and powers jets of relativistic particles that can propagate beyond the host galaxy.

Modern astronomy invests a large amount of effort to search and characterise planetary systems around solar-like stars. In particular, at early stages of their formations in proto-planetary disks.

General Relativity is the most succesful theory we have for describing gravitational phenomena. Its range of applicability is vast: from solar system scales to cosmological scales.

We present the first Event Horizon Telescope (EHT) observations of Sagittarius A* (Sgr A*), the Galactic center source associated with a supermassive black hole.

The clustered nature of star formation leaves a long-term imprint on galaxies, stars, and planets. At young ages, stellar clustering subdivides galaxies into individual building blocks undergoing vigorous, feedback-driven life cycles that vary with the galactic environment.

The cycling of matter in galaxies between molecular clouds, stars and feedback is a major driver of galaxy evolution.

The first billion years witnessed the dawn of the first galaxies, eventually culminating in the final phase change of our Universe: the Epoch of Reionization (EoR). Recent observations allowed us limited glimpses into these epochs, improving our understanding of the timing of the EoR.

Planets interact with their host stars through gravity, radiation and magnetic fields.

OH megamasers (OHMs) are rare, luminous masers found in (ultra-)luminous infrared galaxies ([U]LIRGs). The dominant OH masing line at 1667 MHz can spoof the 1420 MHz neutral hydrogen (HI) line in untargeted HI emission line surveys.

There are a huge number of astrophysical phenomena that remain barely studied due to the lack of large, multiwavelength and deep optical surveys. This is the Universe with the lowest density of stars, largely unseen by past large field surveys like the Sloan Digital Sky Survey (SDSS).

Over the centuries, astronomers have continued to improve the performance of telescopes and the techniques for observing and analysing data. Nowadays, humans are building more and more advanced telescopes with larger and deeper observations, reaching terabytes and even petabytes of data.

The stellar mass function is a fundamental parameter to constrain star formation models. Although the stellar content has been extensively studied since Salpeter's first work in 1955, the study of the planetary mass regime is only now becoming feasible.
