Powerful Yet Lonely: Is 3C 297 a High-redshift Fossil Group?
The Astrophysical Journal Supplement Series, 2022 The environment of the high-redshift ( z = 1.408), powerful radio-loud galaxy 3C 297 has several distinctive features of a galaxy cluster. Among them, a characteristic halo of hot gas revealed by Chandra X-ray observations.

STAR FORMATION ACTIVITY IN CLASH BRIGHTEST CLUSTER GALAXIES [PDF]
, 2015 The CLASH X-ray selected sample of 20 galaxy clusters contains 10 brightest cluster galaxies (BCGs) that exhibit significant (>5σ) extinction-corrected star formation rates (SFRs).

The regulation of star formation in cool-core clusters: imprints on the stellar populations of brightest cluster galaxies [PDF]
, 2015 A fraction of brightest cluster galaxies (BCGs) shows bright emission in the UV and the blue part of the optical spectrum, which has been interpreted as evidence of recent star formation.

The Shape of the Chameleon Fifth-Force on the Mass Components of Galaxy Clusters
UniverseIn the context of chameleon gravity, we present a semi-analytical solution of the chameleon field profile in an accurately modelled galaxy cluster’s mass components, namely the stellar mass of the Brightest Cluster Galaxy (BCG), the baryonic mass in ...

The Central Kinematics and Black Hole Mass of 4C+37.11
The Astrophysical JournalWe report on integral field unit (IFU) measurements of the host of the radio source 4C+37.11. This massive elliptical contains the only resolved double compact nucleus at parsec-scale separation, likely a bound supermassive black hole binary (SMBHB).

The Young and the Wild: What Happens to Protoclusters Forming at Redshift z ≈ 4?
The Astrophysical Journal, 2023 Using one of the largest volumes of the hydrodynamical cosmological simulation suit Magneticum, we study the evolution of protoclusters identified at redshift ≈ 4, with properties similar to the well-observed protocluster SPT2349-56.
