    A mechanism for removing dark matter from galaxies has been found
    The small fraction of dark matter in the galaxy NGC1052-DF4 has worried the astronomical community for several years. Now a team of researchers from the...

    A multiwavelength look into the common evolution of luminous quasars and their host-galaxies
    This talk will be dedicated to luminous (LBol~1E47 erg/s), high-redshift quasars, which are ideal targets to investigate (i) feedback from SMBHs, and (ii) the...

    A new framework for investigating the evolution of Early Type Galaxies
    I present a detailed analysis of the scaling relations of ETGs and suggest a way to predict the evolution of the distributions of galaxies in these planes. This...

    A study shows the unexpected effect of black holes beyond their own galaxies
    At the heart of almost every sufficiently massive galaxy there is a black hole whose gravitational field, although very intense, affects only a small region...
