X-ray binaries (XRBs) are arguably the best sources for studying accretion and jets, because they traverse various accretion states with greatly differing jet strength, over timescales of the order of months, easily amenable to observation. Multi-wavelength variability data, combined with timing analysis techniques, provides information about the

Black holes (BHs) are the pinnacle of extreme gravity. They are responsible for the most violent phenomena observed in the Universe, from long gamma-ray bursts, tidal disruption events to gravitational waves (GW). Despite the recent growth in extragalactic BH discoveries by LIGO-VIRGO, our knowledge of the seed BH population is severely hindered by

ESTALLIDOS includes experts in observational astrophysics, numerical simulations, theoretical modeling, and instrumentation. Working together on "star formation" for more than 20 years, we have played a leading role in the development of the field (> 1000 papers, > 30 PhD Theses). Our strength lies in the complementarity among the different

The magnetic field is the main driver of the spectacular activity of the solar atmosphere, which covers the photosphere, chromosphere, transition region, and corona. This is true also for many other stars, although it is in the Suns atmosphere where we can observe the consequences of the interaction between an astrophysical plasma and its magnetic

The scientific research and technological development projects carried out by the Institute of Astrophysics at its facilities, both at its headquarters in Tenerife and La Palma, and at the Teide and Roque de los Muchachos Observatories, represent an important training and professional experience pool not only for highly specialized researchers and
