Confronting feedback simulations with observations of hot gas in elliptical galaxies
X-ray elliptical galaxies hot gas galaxy evolution
2014/12/23
Elliptical galaxies comprise primarily old stars, which collectively generate a long-lasting feedback via stellar mass-loss and Type Ia SNe. This feedback can be traced by X-ray-emitting hot gas in an...
The UV Upturn in Elliptical galaxies and Environmental Effects

It is suspected that the ultraviolet (UV) upturn phenomenon in elliptical galaxies and extended horizontal-branch stars in globular clusters have a common origin. An extremely high abundance of helium...

In this paper we analyse on, the sample of the local elliptical galax-
ies, some predictions of various cosmological theories. We start with the sample of
ellipticals described in Samurovi¶c (2...
