It is a posit of modern astrophysics that most massive galaxies host a super- massive black hole (millions to billions of times more massive than the Sun).  These black holes affect the evolution of galaxies well beyond their  gravitational sphere of influence (which does not extend wider than 1/

CARMENES is a dual (VIS: 550 to 950 nm; NIR: 950 to 1700 nm) high-resolution spectrograph installed at the 3.5 m telescope at the Calar Alto Observatory (CAHA, Almería, Spain). The NIR channel spectrograph uses the radial-velocity method for detecting exoplanets around low-mass stars.

Observational tests of strong field gravity are improving rapidly. This allows us to test whether the compact objects observed in the sky are truly black holes as described in general relativity or some other "exotic" objects.

The Milky Way nuclear star cluster (NSC) is located within the nuclear stellar disc (NSD) in the Galactic centre. The NSC and NSD are distinct structures of the Milky Way, but also connected to the larger Milky Way structures, e.g.

The ASTRI Collaboration is building at the Teide Astronomical Observatory in Tenerife an array of 9 small Cherenkov telescopes capable of observing with good flux sensitivity, energy and angular resolution the gamma-ray sky above an energy threshold of several hundreds of GeV.

In this talk I will present the design of the Integral Field Unit TARSIS, recently selected to be the next generation multi-object spectrograph for the 3.5m telescope at Calar Alto.

According to the CDM model, galaxy clusters grow through the accretion of individual galaxies and galaxy groups. Thus, it is a true challenge to distinguish the possible role of the present-day host halo from that of previous ones, in the transformation of accreted galaxies.

The nature of fossil groups of galaxies has been debated for over more than 3 decades. This is in part because of the lack of deep multiwavelength data and also due to the low purity of samples selected using solely magnitude gap criteria.

Cosmic rays play an interesting role in understanding the most violent objects in the universe.

The "Lambda cold dark matter'' (LCDM) cosmological model is one of the great achievements in Physics of the past thirty years.

Asteroids, comets, and trans-Neptunian objects are collectively known as small bodies. In a way, they are the debris left by the planetary formation in the Solar system, and as such, they carry a lot of information regarding the processes that shaped it.

We summarize recent research results on the radiation mechanism of the Super Massive Black Hole (SMBH) candidate SgrA* and ask the question if there are Intermediate Mass Black Hole (IMBH) candidates in the central stellar cluster.

EnVision was selected as ESA’s 5th Medium-class mission in the Agency’s Cosmic Vision plan, targeting a launch in the early 2030s. The mission is a partnership between ESA and NASA.

My goal in this colloquium is to apprehend globally the Solar System by describing a vast sample of small bodies, from Near Earth Asteroi

Computational Intelligence (CI) commonly refers to a variety of bio-inspired and/or human-like techniques that can be applied in optimisation, learning and modelling problems.

The interpretation of astronomical observations of comets and asteroids and of extrasolar objects such as protoplanetary and debris disks is crucial for understanding the origin and evolution of planetary systems.

Using broadband radio polarimetry we can probe regions of diffuse ionised and magnetised gas that are challenging to detect by other means, such as in the halos of galaxies (CGM), in galaxy groups and clusters (IGrM/ICM), and filaments of the cosmic web (ie. WHIM).
