The Dark Energy Survey (DES) is a 5000 square degree grizY survey of the Southern sky aimed at understanding the accelerating expansion rate of the Universe. DES is using four complementary methods to
We present a Boltzmann-level observational analysis of an infrared-screened elastic-vacuum(EV) cosmological sector. The model is represented at linear order by a scale-dependent effectivegravitational
The most Xray luminous and massive galaxy clusters are the most interestingobjects for astrophysical and cosmological studies. Completing our REFELX IIcluster survey, we added 10 of the most luminous
