On the Formation of Elliptical Galaxies [PDF]
The Astrophysical Journal, 1975 Simple collapse and violent relaxation models produce sharply cut off envelopes with ϱ(r) ∝ r–4, whereas actual elliptical galaxies have more extended envelopes approximately given by ϱ(r) ∝ r–3 as implied by Hubble's Law. Numerical models are presented, showing that when cosmological infall effects are included, galaxies are produced with more ...

Elliptical galaxies: Rotationally distorted, after all [PDF]
Serbian Astronomical Journal, 2009 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 ...

Tracing Galaxy Evolution by Their Present-Day Luminosity Function
Open Astronomy, 2011 Galaxy luminosity functions are derived for different morphological types and various colors of galaxies, to trace the evolutionary effects which a priori should be different for void and supercluster galaxies.

Clustercentric Distance or Local Density? It Depends on Galaxy Morphology
The Astrophysical Journal, 2023 Determining which between projected local density and distance from the cluster center plays a major role in regulating morphological fractions in clusters is a longstanding debate.

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).

The Astrophysical Journal, 2023 Observational evidence and many numerical simulations show the existence of winds (i.e., uncollimated outflows) in the accretion systems of elliptical galaxy centers.

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 ...
