Estimating turbulent velocities in the elliptical galaxies NGC 5044 and NGC 5813 [PDF]
, 2012 Context. The interstellar and intra-cluster medium (ICM) in giant elliptical galaxies and clusters of galaxies is often assumed to be in hydrostatic equilibrium.

Elliptical Galaxies with Shells [PDF]
International Astronomical Union Colloquium, 1984 A considerable number of otherwise normal elliptical galaxies show sharp edged, low surface brightness concentric features, often at very large radii from the parent galaxy. Features like this are visible in some of the photographs presented by Arp (1966).

Dwarf elliptical galaxies as ancient tidal dwarf galaxies [PDF]
, 2012 The formation of tidal dwarf galaxies (TDGs) is triggered by the encounters of already existing galaxies. Their existence is predicted from numerical calculations of encountering galaxies and is also well documented with observations.

Fundamental Plane of Elliptical Galaxies in f(R) Gravity: The Role of Luminosity
Atoms, 2018 The global properties of elliptical galaxies are connected through the so-called fundamental plane of ellipticals, which is an empirical relation between their parameters: effective radius, central velocity dispersion and mean surface brightness within ...

THE STELLAR HALOS OF MASSIVE ELLIPTICAL GALAXIES [PDF]
, 2012 We use the Mitchell Spectrograph (formerly VIRUS-P) on the McDonald Observatory 2.7 m Harlan J. Smith Telescope to search for the chemical signatures of massive elliptical galaxy assembly.

TESTING YUKAWA-LIKE POTENTIALS FROM f(R)-GRAVITY IN ELLIPTICAL GALAXIES [PDF]
, 2012 We present the first analysis of extended stellar kinematics of elliptical galaxies where a Yukawa-like correction to the Newtonian gravitational potential derived from f(R)-gravity is considered as an alternative to dark matter.
