Descripción
Accretion onto a supermassive black hole (BH) is the most viable explanation for the huge emitted luminosity in active galaxies. Nowadays a wealth of observations have shown the presence of a BH in many nearby inactive bulges, suggesting that all massive spheroids harbor a BH. Moreover, 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. These correlations underline the important fact that there must be 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. Optical (rest-frame 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.

    3D scaling laws and projection effects in The300-NIKA2 Sunyaev-Zeldovich Large Program Twin Samples

    The abundance of galaxy clusters with mass and redshift is a wellknown cosmological probe. The cluster mass is a key parameter for studies that aim to constrain cosmological parameters using galaxy clusters, making it critical to understand and properly account for the errors in its estimates. Subsequently, it becomes important to correctly

    Generating galaxy clusters mass density maps from mock multiview images via deep learning

    Galaxy clusters are composed of dark matter, gas and stars. Their dark matter component, which amounts to around 80% of the total mass, cannot be directly observed but traced by the distribution of diffused gas and galaxy members. In this work, we aim to infer the cluster's projected total mass distribution from mock observational data, i.e. stars
