Formation, Evolution and Properties of Isolated Field Elliptical Galaxies [PDF]
, 2010 [Abridged] We study the properties, evolution and formation mechanisms of isolated field elliptical galaxies. We create a mock catalogue of isolated field elliptical galaxies from the Millennium Simulation Galaxy Catalogue, and trace their merging ...

Chaos and Elliptical Galaxies [PDF]
CELESTIAL MECHANICS AND DYNAMICAL ASTRONOMY, 1995 Recent results on chaos in triaxial galaxy models are reviewed. Central mass concentrations like those observed in early-type galaxies -- either stellar cusps, or massive black holes -- render most of the box orbits in a triaxial potential stochastic ...

Compact Elliptical Galaxies [PDF]
Symposium - International Astronomical Union, 1987 We summarize our present knowledge on low-mass high-surface brightness elliptical objects near massive galaxies that are often called M32-type or compact elliptical galaxies. The origin of the low mass of these objects is a controversial matter: is it intrinsic to their formation or produced, as classically believed, by tidal stripping from the massive

The formation history of elliptical galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2005 We take advantage of the largest high-resolution simulation of cosmic structure growth ever carried out - the Millennium Simulation of the concordancecold dark matter (CDM) cosmogony - to study how the star formation histories, ages and metallicities of ...

The Elliptical-Spheroidal and Elliptical-Elliptical Galaxy Dichotomies [PDF]
arXiv, 2008 This paper summarizes Kormendy et al. (2009, ApJS, in press, arXiv:0810.1681). We confirm that spheroidal galaxies have fundamental plane correlations that are almost perpendicular to those for bulges and ellipticals. Spheroidals are not dwarf ellipticals. They are structurally similar to late-type galaxies.

Dark Matter in Elliptical Galaxies [PDF]
, 2011 We review X-ray constraints on dark matter in giant elliptical galaxies \(({10}^{12}\,{M}_{\odot }\lesssim{M}_{vir} \lesssim1{0}^{13}\,{M}_{\odot })\)obtained using the current generation of X-ray satellites, beginning with an overview of the physics of ...

The Relationship between Slope and Luminosity [PDF]
Kirkuk Journal of Science, 2010 In this study, a sample of galaxies has been adopted. It consists of 112 elliptical galaxies, among them were 56 dwarf elliptical galaxies, which belong to virgo cluster, 37 normal galaxies and 19 bright galaxies. Also, surface brightness profiles fitted

Deviations of the Surface Brightness Distribution in Isolated Elliptical Galaxies [PDF]
مجلة التربية والعلم, 2012 In this paper, we present the surface brightness profiles of 48 isolated elliptical galaxies. we have adopted the r1/n – law to the observed surface brightness profiles of the adopted sample of isolated elliptical galaxies for the intermediate radial ...

Planetary Nebulae and the Ionization of the Interstellar Medium in Galaxies
Frontiers in Astronomy and Space Sciences, 2022 We discuss the role of planetary nebulae and their progeny in galaxy context in terms of ionization of the galaxy interstellar medium. This regards ionized gas outside the disk of spiral galaxies, the diffuse ionized medium in spiral galaxies, and the ...
