A Candidate Brightest Proto-Cluster Galaxy at z = 3.03

, 2008
We report the discovery of a very bright (m_R = 22.2) Lyman break galaxy at z = 3.03 that appears to be a massive system in a late stage of merging. Deep imaging reveals multiple peaks in the brightness profile with angular separations of ~0.''8 (~25 h ...

The X-ray coronae of the two brightest galaxies in the Coma cluster [PDF]

, 2014
We use deep Chandra X-ray Observatory observations to examine the coronae of the two brightest cluster galaxies in the Coma cluster of galaxies, NGC 4874 and NGC 4889.

LoCuSS: the connection between brightest cluster galaxy activity, gas cooling and dynamical disturbance of X‐ray cluster cores [PDF]

, 2009
We study the distribution of projected offsets between the cluster X-ray centroid and the brightest cluster galaxy (BCG) for 65 X-ray-selected clusters from the Local Cluster Substructure Survey, with a median redshift of z = 0.23.

A Submillimeter Selected Quasar in the Field of Abell 478

, 2000
We report the discovery of a z=2.83 quasar in the field of the cooling flow galaxy cluster Abell 478. This quasar was first detected in a submm survey of star forming galaxies at high redshifts, as the brightest source.

Order statistics of the early-type galaxy luminosity function [PDF]

, 2011
We apply order statistics (OS) to the bright end ($M_r < -22$) of the luminosity distribution of early-type galaxies spectroscopically identified in the SDSS DR7 catalog.

A Large Mass of H2 in the Brightest Cluster Galaxy in Zwicky 3146 [PDF]

, 2006
We present the Spitzer/IRS mid-infrared spectrum of the infrared-luminous (LIR = 4 × 1011 L☉) brightest cluster galaxy (BCG) in the X-ray-luminous cluster Zwicky 3146 (Z3146; z = 0.29).

Mimicking Symmetry‐Breaking Einstein Ring by Optical Lens

Advanced Photonics Research, Volume 6, Issue 6, June 2025.
This article uses an optical lens to emulate the gravitational lensing effect and observe the Einstein ring (ER) patterns. The symmetry‐breaking ER, i.e., Einstein cross, is observed utilizing a rotation‐symmetry‐breaking hemi‐ellipsoid lens. Deformed Einstein cross patterns induced by noncollinearly alignment of the light source–lens–observer are ...

Silicosarcoidosis: Histologic and Clinical Features of an Occupational Granulomatous Disease

American Journal of Industrial Medicine, Volume 68, Issue 6, Page 491-507, June 2025.
ABSTRACT Sarcoidosis is a multisystem inflammatory disease of unknown etiology. Growing evidence indicates that occupational exposure to respirable crystalline silica (RCS) is associated with an increased incidence of sarcoidosis. Yet a diagnosis of sarcoidosis rarely prompts investigation to identify preventable exposures.
