Descripción
Accretion onto a black hole (BH) is the most viable explanation for the huge emitted power in active galaxies. A wealth of observations have shown the presence of a BH in many nearby inactive bulges, suggesting that all massive spheroids harbor a BH. At low redshift, fundamental correlations have been found between the BH mass and the luminosity (mass) and the central velocity dispersion of the host galaxy bulge, indicating a strong relationship between the formation and evolution of massive bulges and their central BH. We discuss our ongoing program to investigate the cosmic evolution of this relationship. Rest-UV spectroscopy is used to determine the virial BH masses of a large sample of high-redshift quasars for which the host galaxy luminosity is reliably determined from our previous VLT imaging.

    RAD@home Citizen Scientists Uncover Emerging Jet-Galaxy Interactions
    The RAD12 object's recent investigation (Hota et al. 2022), via the RAD@home Astronomy Collaboratory, has provided a streamlined and focused perspective on the complex subject of jet-galaxy interactions, which has always posed a significant challenge for observational confirmation. This emerging field holds increasing significance, providing a

    A Disc Wind Where You Least Expect It: The Outflow in the Short-period X-ray Binary UW CrB
    Studying outflows of low mass X-ray binaries (LMXBs) is important for understanding the physics of accretion, the evolution of compact binaries, and dynamics of the local interstellar medium. One significant source of these outflows is the accretion disc wind, which can blow away vast amounts of material from the disc before it can be accreted on

    Constraining the core-rotation rate along the red-giant evolution
    The evolution of the core rotation rate of red giant stars is a key parameter in understanding the stellar behavior in the late phases of stellar evolution. Thanks to the mixed-dipole modes, we can constrain the core rotation and internal rotational gradient as a star advances through the red-giant phase. This master thesis presents a pipeline
