Elliptical galaxies: Rotationally distorted, after all [PDF]
On the basis of earlier investigations on homeoidally striated Mac Laurin spheroids and Jacobi ellipsoids (Caimmi and Marmo 2005, Caimmi 2006a, 2007), different sequences of configurations are defined and represented in the ellipticity-rotation plane ...

The Relationship between Slope and Luminosity [PDF]
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

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]
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
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 ...

Phenomenological approach to the modelling of elliptical galaxies: The problem of the mass-to-light ratio [PDF]
In this paper the problem of the phenomenological modelling of elliptical galaxies using various available observational data is presented. Recently, Tortora, Cardona and Piedipalumbo (2007) suggested a double power law expression for the global ...

The observed Tully-Fisher and Faber-Jackson laws between the baryonic mass of galaxies and the velocity of motion of stars at the edge of galaxies are explained within the framework of the model of accretion of galaxies around supermassive black holes ...

In this paper, we present the simple, one-step, self-consistent, and fast resonance scattering model rsapec based on the AtomDB database. This model can be used as an alternative to the commonly used APEC model for fitting X-ray spectra with optically ...
