Description
CTA is the next generation gamma-ray observatory which will conduct observations from both hemispheres in the energy range from 20 GeV to more than 300 TeV with an unprecedented sensitivity and angular resolution. Several Key Science Projects have been prepared by the CTA consortium to shed light on long standing questions of production mechanisms of gamma rays in extragalactic sources and reasons for the temporal variability in gamma rays which we observe. Also, CTA will allow us to determine the evolution in redshift of the low energy background radiation, the so-called EBL, which provides insights into the evolution of the galaxies as well as an independent measurement of the Hubble constant. In this presentation I will discuss the prospects of some of these studies and possible synergies with other research fields.
