SUMMARY:The early growth of (super)massive black holes
DESCRIPTION:With detections of quasars powered by increasingly massive black holes\n(BH) at increasingly early times in cosmic history over the past decade\,\nthere has been correspondingly rapid progress made on the theory of early\nBH formation and growth. I review the emerging picture of how the first\nmassive BHs formed from the primordial gas and then grew to supermassive\nscales\, and discuss the initial conditions for the formation of the\nprogenitors of these seed BHs\, the factors dictating the initial masses\nwith which they form\, and their initialstages of growth via accretion\,\nwhich may occur at super-Eddington rates.

SUMMARY:May a single hypothesis to explain most of the mysteries of the universe?
DESCRIPTION:A single hypothesis on the properties of the gravitational interaction\nin the presence of antimatter could explain\, simultaneously: the asymmetry\nbetween matter and antimatter at cosmic level\, the inflation\, the effects attributed\nto dark matter and dark energy\, and at elementary particle level CPV and the arrow of time.

SUMMARY:Metals outside galaxies: what do we learn from observations?
DESCRIPTION:The observed properties and evolution of galaxies in the Universe require the existence of feedback mechanisms regulating the star formation and finally quenching it. The presence of winds\, possibly transporting the gas outside the viral radius\, has been confirmed observationally in local and high redshift objects. In this talk\, I will briefly review how scientist have confirmed the presence of heavy elements outside galaxies using the observation of QSO absorption lines and I will present and discuss new results based on the highest signal-to-noise ratio\, high resolution QSO spectrum ever obtained.

SUMMARY:Linking massive black hole spin evolution to galactic dynamics
DESCRIPTION:The evolution of the spin of massive black holes (MBHs) is driven by accretion of gas and/or by black hole binary coalescences. I will discuss the physical processes involved in the MBH spin evolution\, and present the results of a semi-analytical model that manages to reproduce the distribution of spins obtained from X-ray spectroscopy.
