Investigation of the Fundamental Plane Relationship For the Evolution of the Elliptical and Lenticular Galaxies [PDF]
مجلة التربية والعلمThe Fundamental Plane relates the effective radius and surface brightness of an early-type galaxy to its velocity dispersion. It is important in understanding galaxy formation and evolution processes. The present work aims to investigate this relation as

Galaxy Light Concentration. I. Index stability and the connection with galaxy structure, dynamics, and supermassive black holes [PDF]
, 2001 We explore the stability of different galaxy light concentration indices as a function of the outermost observed galaxy radius. With a series of analytical light-profile models, we show mathematically how varying the radial extent to which one measures a

Double-nucleus elliptical MCG-01-12-005 in an X-ray emitting cluster of galaxies [PDF]
, 2015 The scenario of galaxy formation is believed to follow a structure that builds up from the bottom, with large galaxies being formed by several merging episodes of smaller ones.

The Manifold of Elliptical Galaxies [PDF]
Symposium - International Astronomical Union, 1987 Global properties of elliptical galaxies, such as the luminosity, radius, projected velocity dispersion, projected luminosity density, etc., form a two-dimensional family. This “fundamental plane” of elliptical galaxies can be defined by the velocity dispersion and mean surface brightness, and its thickness is presently given by the measurement error ...

Revealing the dynamical behavior of stars in a prolate or oblate elliptical galaxy
Results in Physics, 2023 We consider the motion of a test particle (star) on the meridian plane (R,z) of an elliptical galaxy with an additional central nucleus component. The shape of the elliptical galaxy can be either prolate or oblate, or even spherical by simply changing ...

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 ...
