X-ray properties expected feedback elliptical galaxies
2011/10/11
The ISM evolution of elliptical galaxies experiencing feedback from accretion onto a central black hole was studied recently with high-resolution 1D hydrodynamical simulations including radiative heat...
The UV Upturn in Elliptical galaxies and Environmental Effects

2011/8/24
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...

2011/1/11
Photometric data from the literature is combined with triaxial mass models to derive variation in the intrinsic shapes of the light distribution of elliptical galaxies NGC 720, 2768 and 3605. The infe...

The existence of hot, X-ray luminous gaseous coronae surrounding present day L? galaxies
is a generic prediction of galaxy formation theory in the cold dark matter cosmogony.
While extended X-ray em...
A SAURON study of dwarf elliptical galaxies in the Virgo Cluster
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/29
Dwarf elliptical galaxies are the most common galaxy type in nearby galaxy clusters, yet they remain relatively poorly studied objects and many of their basic properties have yet to be quantified. In ...
ELLIPTICAL GALAXIES: ROTATIONALLY DISTORTED, AFTER ALL
Galaxies: kinematics and dynamics Galaxies: elliptical and lenticular cD
2010/10/29
A possible interpretation of slow rotators as nonrotating at all and elongated due to negative anisotropy parameters, instead of flattened due to positive anisotropy parameters, is exploited. Finally,...
