Stellar Populations in the Dwarf Elliptical Galaxy NGC 147
, 1993 Deep V and I CCD images in a central and an outer field of the Local Group dwarf elliptical galaxy NGC 147 have been obtained with the Wide Field and Planetary Camera-2 (WFPC2) on board of the Hubble Space Telescope.

On The Parent Population of Radio Galaxies and the FR I--II Dichotomy [PDF]
arXiv, 2001 The possibility of radio galaxies being random sample of otherwise normal elliptical galaxies is tested. Starting with the observed optical luminosity functions for elliptical galaxies, it is shown that the probability of an elliptical forming a radio source is a continuous, increasing function of optical luminosity, precisely proportional to square of

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

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 ...

The Planetary Nebula System and Dynamics in the Outer Halo of NGC 5128
, 2003 The halos of elliptical galaxies are faint and difficult to explore, but they contain vital clues to both structure and formation. We present the results of an imaging and spectroscopic survey for planetary nebulae (PNe) in the nearby elliptical NGC 5128.

, 2015 In this thesis, a sample of nearby, compact, elliptical galaxies with high central stellar velocity dispersions are studied. By means of high quality photometric and spectroscopic observations, we analyse their structural properties and construct state-of-the-art orbit-based dynamical models to constrain their total mass budgets, including the ...

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.

Searching for tidal tails - investigating galaxy harassment
, 2005 Galaxy harassment has been proposed as a physical process that morphologically transforms low surface density disc galaxies into dwarf elliptical galaxies in clusters.
