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.

Hoag’s Object: evidence for cold accretion on to an elliptical galaxy [PDF]
, 2011 We present new photometric and spectroscopic observations of the famous Hoag’s Object, a peculiar ring galaxy with a central roundish core. The nature of Hoag’s Object is still under controversy. Previous studies demonstrated that a major accretion event

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.

A Cosmological Framework for the Co-Evolution of Quasars, Supermassive Black Holes, and Elliptical Galaxies. I. Galaxy Mergers and Quasar Activity [PDF]
, 2007 We develop a model for the cosmological role of mergers in the evolution of starbursts, quasars, and spheroidal galaxies. By combining theoretically well-constrained halo and subhalo mass functions as a function of redshift and environment with empirical

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

ELLIPTICAL GALAXY MASSES OUT TO FIVE EFFECTIVE RADII: THE REALM OF DARK MATTER [PDF]
, 2011 We estimate the masses of elliptical galaxies out to five effective radii using planetary nebulae and globular clusters as tracers. A sample of 15 elliptical galaxies with a broad variation in mass is compiled from the literature. A distribution function-
