Spectroscopic and X-ray Modeling of the Strong Lensing Galaxy Cluster MACS J0138.0-2155
The Open Journal of AstrophysicsWe model the total mass and galactic substructure in the strong lensing galaxy cluster MACS J0138.0-2155 using a combination of Chandra X-ray data, Multi-Unit Spectroscopic Explorer (MUSE) spectroscopy, and Hubble Space Telescope imaging.

Brightest Cluster Galaxy Evolution Exploration: Comparing the Separation of Cluster X-ray Light and Visible Wavelength Galaxy Light with Spectral Data [PDF]
, 2019 Brightest Cluster Galaxies (BCGs), the brightest galaxy in a cluster of hundreds to thousands of galaxies, are some of the biggest, brightest, and most massive galaxies in the universe. Characterizing a BCG can help discover more about galaxy evolution -

PEARLS: Globular Clusters and Ultracompact Dwarfs in the El Gordo Galaxies at z = 0.87
The Astrophysical JournalJWST/NIRCam 0.9 to 2.0 μ m images reveal a population of point sources around the major galaxies in the El Gordo cluster at redshift z = 0.87. Their distribution in the color–magnitude diagrams shows a narrow sequence well separated from field-galaxy ...

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.

Coevolution of intracluster light and brightest cluster galaxies
Astronomy & AstrophysicsContext. Intracluster light (ICL) is a faint stellar component of galaxy groups and clusters bound to the cluster potential, making up a significant fraction of the cluster mass. The ICL formation and evolution is strongly linked to the brightest cluster galaxies (BCGs) of clusters.

Forged by Feedback: Stellar Properties of Brightest Group Galaxies in Cosmological Simulations
The Astrophysical JournalWe investigate how different galaxy formation models impact the stellar properties of brightest group galaxies (BGGs) in four cosmological simulations: R omulus , S imba , S imba -C, and O bsidian .
