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).

Loss of PI3Kδ Activity Drives Autoimmune Colitis by Impairing Extrathymic Treg Differentiation

European Journal of Immunology, Volume 55, Issue 10, October 2025.
Mice with inactivated PI3Kδ develop colitis, reminiscent of immune‐related adverse effects observed in human patients treated with PI3Kδ inhibitors. We demonstrate that loss of PI3Kδ activity abrogates the Helios− peripherally induced Treg (pTreg) population in the mouse colon, resulting in inflammation and tissue damage that Helios+ thymic Tregs fail ...

Galaxy Superclusters Detected in the Modified PF-Catalog Using the FOF Method

Open Astronomy, 2011
The Modified Catalog of Galaxy Clusters and Groups (Panko & Flin 2006, PF), covering an area of 5000 square degrees in the southern sky, was used as the input for the search of galaxy superclusters.

Early Science with the Karoo Array Telescope: a Mini-Halo Candidate in Galaxy Cluster Abell 3667

, 2014
Abell 3667 is among the most well-studied galaxy clusters in the Southern Hemisphere. It is known to host two giant radio relics and a head-tail radio galaxy as the brightest cluster galaxy.

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.

A Chromosome Inversion Creates a Supergene for Sex and Colour in Lake Malawi Cichlids

Molecular Ecology, Volume 34, Issue 20, October 2025.
ABSTRACT Cichlid fishes have the highest rates of evolutionary turnover of sex chromosomes among vertebrates. Many large structural polymorphisms in the radiation of cichlids in Lake Malawi are associated with sex chromosomes and may also carry adaptive variation.

Tracing Dark Matter in the Central Regions of Galaxy Clusters Using Galaxies, Gas, and Intracluster Light in TNG300: Connections to Cluster Dynamical State

The Astrophysical Journal
Recent studies have highlighted the potential of intracluster light (ICL) as a dark matter tracer. Moreover, ICL coevolves with the brightest cluster galaxy (BCG) and the host cluster, making it a valuable tool for understanding cluster dynamics. In this

Extended Radio Emission in the Perhipheral Regions of the Shapley Concentration Core

Galaxies, 2017
The Shapley Concentration (SC) is a galaxy supercluster (few tens of degrees) in the Local Universe (<z>∼0.048) which is currently undergoing cluster mergers and group accretion.
