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...
Elliptical Weighted HOLICs for Weak Lensing Shear Measurement part2:PSF correction and application to Abell 370
Elliptical Weighted HOLICs for Weak Lensing Shear Measurement part2:PSF correction and application to Abell 370
2011/10/20
We have developed a new method(E-HOLICs) of estimating gravitational shear by adopting an elliptical weight function to measure background galaxy images in our previous paper. Following to the previou...
The SAURON Project - XIX. Optical and near-infrared scaling relations of nearby elliptical, lenticular and Sa galaxies
galaxies: bulges – galaxies: elliptical and lenticular, cD – galaxies: photometry – galaxies: structure – galaxies: stellar content – galaxies: fundamental parameters
2011/9/27
[Abridged] We present ground-based MDM V-band and Spitzer/IRAC 3.6um-band photometric observations of the 72 representative galaxies of the SAURON Survey. In combination with the SAURON stellar veloci...
The UV Upturn in Elliptical galaxies and Environmental Effects
Elliptical galaxies Environmental Effects
2011/9/26
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...
