The Outer Halos of Elliptical Galaxies [PDF]
, 2010 Recent progress is summarized on the determination of the density distributions of stars and dark matter, stellar kinematics, and stellar population properties, in the extended, low surface brightness halo regions of elliptical galaxies. With integral field absorption spectroscopy and with planetary nebulae as tracers, velocity dispersion and rotation ...

The Astrophysical Journal, 1983 We propose that dwarf elliptical galaxies are the bound remnants of more massive stellar systems, such as a parent galaxy which has lost more than half its mass in gas ejection during a burst of star formation, or an unbound tidal debris produced during the interaction of two giant galaxies.

Stellar Population Synthesis of the Elliptical Galaxy NGC 4649 [PDF]
Journal of Astronomy and Space Sciences, 2001 We investigated population of the elliptical galaxy NGC 4649 using the spectral synthesis technique based on the linear program in the spectral regions between 3160Å to 10800Å. We used the spectral data of stars obtained by Gunn & Stryker (1983), and the

, 2002 Neutral hydrogen is an important component of the interstellar medium in elliptical galaxies as well as a potentially valuable mass tracer. Until recently, HI surveys of early-type galaxies have been sparse and inhomogeneous but this has changed with the advent of the HI Parkes All-Sky Survey (HIPASS; Barnes et al. 2001). We discuss HIPASS observations

Absorption Line Gradients of an Elliptical Galaxy NGC 5322 [PDF]
Journal of Astronomy and Space Sciences, 1999 Archival long-slit spectra, covering the wavelength range 4050Å - 5150Å, have been used to investigate the radial behavior of absorption line features (G4300, Fe4383, Ca4455, Fe44531, Fe4668, and Hα) of an eliptical galaxy NGC 5322.

A New Dynamical Parameter for the Study of Sticky Orbits in a 3D Galactic Model
Open Astronomy, 2011 A 3D dynamical model is used to study the motion in the central parts of an elliptical galaxy, hosting a massive and dense nucleus. Our aim is to investigate the regular or chaotic character of the motion, with emphasis in the different chaotic ...

Evolution of Massive Red Galaxies in Clusters from z = 1.0 to z = 0.3
The Astronomical JournalA critical issue in studying the evolution of galaxy clusters is to find ways that enable meaningful comparisons of clusters observed at different redshifts, as well as in various stages of their growth.
