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 ...

Confirmation of Enhanced Dwarf-sensitive Absorption Features in the Spectra of Massive Elliptical Galaxies: Further Evidence for a Non-universal Initial Mass Function [PDF]
, 2011 We recently found that massive cluster elliptical galaxies have strong Na I 8183,8195 and FeH 9916 Wing-Ford band absorption, indicating the presence of a very large population of stars with masses

A new method for the identification of non-Gaussian line profiles in elliptical galaxies
, 1993 A new parameterization for the line profiles of elliptical galaxies, the Gauss-Hermite series, is proposed. This approach expands the line profile as a sum of orthogonal functions which minimizes the correlations between the errors in the parameters 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 ...

Isolated compact elliptical galaxies: Stellar systems that ran away [PDF]
Science, 2015 Galaxies stripped down and evicted It is easy to imagine that the relatively small and dense compact elliptical galaxies once had more to them. Especially when massive galactic neighbors are seen nearby that may have robbed them of their matter, but ...

The Astrophysical Journal, 2023 The mechanism by which galaxies stop forming stars and get rid of their interstellar medium (ISM) remains elusive. Here, we study a sample of more than 2000 elliptical galaxies in which dust emission has been detected.

Why there are no elliptical galaxies more flattened than E7: Thirty years later [PDF]
Serbian Astronomical Journal, 2006 Elliptical galaxies are modeled as homeoidally striated Jacobi ellipsoids (Caimmi and Marmo 2005) where the peculiar velocity distribution is anisotropic, or equivalently as their adjoint configurations i.e.
