The Shapes and Ages of Elliptical Galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1996
Normally elliptical galaxies are thought to be old, evolved systems, but recently a controversy has arisen over the age of ellipticals. Measurements by Gonzáles (1993, Ph.D. thesis, UCSC) show that the Hβ absorption indices of ellipticals span a range of values.

Investigation of the Fundamental Plane Relationship For the Evolution of the Elliptical and Lenticular Galaxies [PDF]

open access: yesمجلة التربية والعلم
The 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]

open access: yes, 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

open access: yesThe 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.

The supermassive black hole mass-Sérsic index relations for bulges and elliptical galaxies [PDF]

open access: yes, 2013
Scaling relations between supermassive black hole mass, MBH, and host galaxy prop- erties are a powerful instrument for studying their coevolution. A complete picture involving all of the black hole scaling relations, in which each relation is consistent

A Preferential Growth Channel for Supermassive Black Holes in Elliptical Galaxies at z ≲ 2

open access: yesThe 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 different star formation histories of blue and red spiral and elliptical galaxies [PDF]

open access: yes, 2013
We study the spectral properties of intermediate mass galaxies (M* ∼ 1010.7 M⊙) as a function of colour and morphology. We use Galaxy Zoo to define three morphological classes of galaxies, namely early types (ellipticals), late-type (disc-dominated) face-

Elliptical galaxies: Rotationally distorted, after all [PDF]

open access: yesSerbian 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 ...
