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

The Look-back Time Evolution of Far-Ultraviolet Flux from the Brightest Cluster Elliptical Galaxies at z < 0.2 [PDF]
, 2007 We present the GALEX UV photometry of the elliptical galaxies in Abell clusters at moderate redshifts (z < 0.2) for the study of the look-back time evolution of the UV upturn phenomenon. The brightest elliptical galaxies (M_r < -22) in 12 remote clusters

Mass Dependence of Galaxy–Halo Alignment in LOWZ and CMASS
The Astrophysical Journal, 2023 We measure the galaxy-ellipticity (GI) correlations for the Sloan Digital Sky Survey Data Release 12 LOWZ and CMASS samples with the shape measurements from the DESI Legacy Imaging Surveys.

A Preferential Growth Channel for Supermassive Black Holes in Elliptical Galaxies at z ≲ 2
The Astrophysical Journal, 2023 The assembly of stellar and supermassive black hole (SMBH) mass in elliptical galaxies since z ∼ 1 can help to diagnose the origins of locally observed correlations between SMBH mass and stellar mass.

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 ...

The Manifold of Elliptical Galaxies [PDF]
Symposium - International Astronomical Union, 1983 The significant number of dimensions of the manifold is two. Notwithstanding the contamination of the second dimension by projection effects, there are arguments for an intrinsic variation.

Multiple minor mergers: formation of elliptical galaxies and constraints for the growth of spiral disks [PDF]
, 2007 Multiple, sequential mergers are unavoidable in the hierarchical build-up picture of galaxies, in particular for the minor mergers that are frequent and highly likely to have occured several times for most present-day galaxies.
