Cosmology and Astrophysics with the Diffuse eRASS1 X-Ray Angular Power Spectrum

The recent tension in the value of the cosmological parameter ${S}_{8}\equiv {\sigma }_{8}{({{\rm{\Omega }}}_{M}/0.3)}^{1/2}$ , which represents the amplitude of the matter density fluctuations of the Universe, has not been resolved. In this work, we present constraints on S _8 with the X-ray angula...
