A substantial population of low-mass stars in luminous elliptical galaxies [PDF]

Nature, 2010
The stellar initial mass function (IMF) describes the mass distribution of stars at the time of their formation and is of fundamental importance for many areas of astrophysics.

X-ray Properties of Young Early Type Galaxies: II. Abundance Ratio in the Hot ISM

, 2012
Using Chandra X-ray observations of young, post-merger elliptical galaxies, we present X-ray characteristics of age-related observational results, by comparing with typical old elliptical galaxies in terms of metal abundances in the hot interstellar ...

The Gravitational Lens CFRS03.1077 [PDF]

, 2002
An exquisite gravitational arc with a radius of 2.1" has been discovered around the z = 0.938 field elliptical galaxy CFRS03.1077 during HST observations of Canada-France Redshift Survey (CFRS) fields.

Dissecting the size evolution of elliptical galaxies since z∼ 1: puffing-up versus minor-merging scenarios [PDF]

, 2011
At a fixed stellar mass, the size of low-redshift early-type galaxies is found to be a factor of 2 larger than that of their counterparts at z∼ 1, a result with important implications for galaxy formation models.

Alignment of galaxies relative to their local environment in SDSS-DR8

, 2016
We study the alignment of galaxies relative to their local environment in SDSS-DR8 and, using these data, we discuss evolution scenarios for different types of galaxies. We defined a vector field of the direction of anisotropy of the local environment of

Chandra observation of the central galaxies in A1060 cluster of galaxies [PDF]

, 2002
Chandra observation of the central region of the A1060 cluster of galaxies resolved X-ray emission from two giant elliptical galaxies, NGC 3311 and NGC 3309. The emission from these galaxies consists of two components, namely the hot interstellar medium (

Weak homology of elliptical galaxies [PDF]

Astronomy & Astrophysics, 2002
We start by studying a small set of objects characterized by photometric profiles that have been pointed out to deviate significantly from the standard R^{1/4} law. For these objects we confirm that a generic R^{1/n} law, with n a free parameter, can provide superior fits (the best-fit value of n can be lower than 2.5 or higher than 10), better than ...
