Description
The large scale structure of the Universe at redshift 2<z<3 is
displaying a transition from the most overdense protoclusters to the
first massive, virialized halos, on a time scale of about one
Gyr. While gravity is driving this evolutionary step, a plethora of
very energetic phenomena becomes visible at all wavelengths in the
member galaxies. Particularly, high-resolution X-ray observations
play an important role in characterizing nuclear activity and
obscuration level in high density environments, diffuse Inverse
Compton emission from radio jets, thermal emission from the
(proto)intracluster medium, and the effect of nuclear feedback on the
environment on scales from tens of kpc to Mpc. We present recent
studies on nuclear activity in protoclusters from Chandra deep
observations and their implications in the context of galaxy
evolution.
