The Growth in Size and Mass of Cluster Galaxies since z=2

, 2013
We study the formation and evolution of Brightest Cluster Galaxies starting from a $z=2$ population of quiescent ellipticals and following them to $z=0$.

The Intracluster Light of Abell 3667: Unveiling an Optical Bridge in LSST Precursor Data

The Astrophysical Journal Letters
Intracluster light (ICL), the diffuse glow of stars stripped from galaxies during a cluster’s formation, is an established tracer of a cluster’s dynamical history. The upcoming Vera C.

Reassessing the Relationship Between Meteor Radio Afterglows and Optical Persistent Trains

Journal of Geophysical Research: Space Physics, Volume 130, Issue 9, September 2025.
Abstract Meteor radio afterglows (MRAs) and optical persistent trains (PTs) are two types of long‐lived phenomena which are occasionally observed following the occurrence of a meteor. Both phenomena are thought to be produced by intrinsic emission mechanisms; PTs have been associated with chemiluminescent reactions between meteoric metals and ...

Luminous Red Galaxies in Clusters: Central Occupation, Spatial Distributions, and Mis-centering [PDF]

, 2015
Luminous Red Galaxies (LRG) from the Sloan Digital Sky Survey are considered among the best understood samples of galaxies, and they are employed in a broad range of cosmological studies.

Evolution of Massive Red Galaxies in Clusters from z = 1.0 to z = 0.3

The Astronomical Journal
A critical issue in studying the evolution of galaxy clusters is to find ways that enable meaningful comparisons of clusters observed at different redshifts, as well as in various stages of their growth.

The luminosities of the brightest cluster galaxies and brightest satellites in SDSS groups

, 2012
We show that the distribution of luminosities of Brightest Cluster Galaxies in an SDSS-based group catalog suggests that BCG luminosities are just the statistical extremes of the group galaxy luminosity function.

Reexamination of the CO Absorption Line in the M87 Nucleus

The Astrophysical Journal
We analyzed the archival Atacama Large Millimeter/submillimeter Array data of the nuclear region of M87 and evaluated the molecular gas content from the CO(2–1) absorption line.

A Study of Catalogued Nearby Galaxy Clusters in the SDSS-DR4: I. Cluster Global Properties

, 2007
We have selected a sample of 88 nearby (z 800$ km s$^{-1}$). However, the local environment could play a key role in galaxy evolution for low mass clusters.Comment: 19 pages, 11 figures, accepted for publication in A&

High-redshift Merger-induced Bar-like Galaxies in IllustrisTNG

The Astrophysical Journal Letters
Recent discoveries made with JWST observations include a significant number of barred galaxies at high redshift. Their origin remains unclear, and their presence seems difficult to reproduce in cosmological simulations of galaxy formation and evolution ...

The Outer Halos of Very Massive Galaxies: BCGs and their DSC in the Magneticum Simulations

Galaxies, 2017
Recent hydrodynamic cosmological simulations cover volumes up to Gpc 3 and resolve halos across a wide range of masses and environments, from massive galaxy clusters down to normal galaxies, while following a large variety of physical processes ...
