Structural properties of dwarf ellipticals and the connection with (ordinary) elliptical galaxies [PDF]

open access: yesProceedings of the International Astronomical Union, 2005
This article reviews the popular reasons for the belief that dwarf elliptical galaxies and (ordinary) elliptical galaxies are distinct and separate species. They include: light-profile shape (or similarly image concentration); the magnitude-central surface brightness diagram; the magnitude-effective surface brightness diagram (or similarly the ...

UV Visibility of Moderate-Redshift Giant Elliptical Galaxies [PDF]

open access: yesJournal of Astronomy and Space Sciences, 1998
We show quantitatively whether giant elliptical galaxies would be visible at far UV wavelengths if they were placed at moderate redshift of 0.4-0.5. On the basis of simple cosmological tests, we conclude that giant elliptical galaxies can be detectable ...

The Relationship between Slope and Luminosity [PDF]

open access: yesKirkuk 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]

open access: yesمجلة 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 ...

The Fate of the Interstellar Medium in Early-type Galaxies. II. Observational Evidence for Morphological Quenching

open access: yesThe 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]

open access: yesSerbian 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.

Planetary Nebulae and the Ionization of the Interstellar Medium in Galaxies

open access: yesFrontiers 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 ...
