#REDSHIFT PHYSICS FULL#
In a full multiwavelength approach, by obtaining and using data from all major observational facilities (both in space and on the ground) we will aim to clarify the physical trigger of downsizing, catch AGN feedback in action and assess its role in galaxy transformations, along with the effects of the environment, gas accretion, star formation and merging in driving galaxy formation. Gravitational redshift G is the gravitational constant, M is the mass of the object creating the gravitational field, r is the radial coordinate of the source (which is analogous to the classical distance from the center of the object. With three postdocs each year for a total of 5 years, we will pave new avenues towards understanding the relation between black holes and galaxies at the time of their major mass growth and assembly. The bigger the red-shift the faster the star is moving away.

Building on the legacy of these discoveries and critical results, I ask for support to fund the establishment of a new research team to lead research aimed at exploring the physics of galaxy formation in the distant Universe. Understanding the nature and physics of low-mass galaxies can help inform almost every aspect of galaxy formation and evolution. A red-shift in the light from a star shows that the distance between us and the star is increasing. These include molecular gas first seen in typical high-z galaxies the major phase of star formation at very high rates widespread presence of previously unknown Compton-thick AGNs inside massive galaxies and the existence of evolved galaxy clusters containing X-ray emitting gas already at z~2. Thanks to a new galaxy selection technique that I recently introduced, I have been leading research projects that have now provided major new results on high redshift z~2 galaxies. This requires to observationally constrain and clarify the physical processes that operated at those early epochs. We now have a fairly detailed census of the diverse high-z galaxy populations, hence time is ripe for fundamental advances in understanding galaxy formation and evolution in the crucial first few billion years.

Understanding the processes regulating galaxy formation is a major open issue in observational cosmology.
