Deep Chandra observations of Abell 2495: a possible sloshing-regulated feedback cycle in a triple-offset galaxy cluster
Luca Rosignoli, Francesco Ubertosi, Myriam Gitti +6
We present the analysis of new, deep observations (130~ks) of the galaxy cluster Abell~2495. This object is known for the presence of a triple offset between the peaks of…
Jet reorientation in central galaxies of clusters and groups: insights from VLBA and Chandra data
Francesco Ubertosi, Gerrit Schellenberger, Ewan O'Sullivan +8
Recent observations of galaxy clusters and groups with misalignments between their central AGN jets and X-ray cavities, or with multiple misaligned cavities, have raised concerns a…
Weak-Lensing Analysis of the Complex Cluster Merger Abell 746 with Subaru/Hyper Suprime-Cam
Kim HyeongHan, Hyejeon Cho, M. James Jee +15
The galaxy cluster Abell 746 (A746; =0.214), featuring a double radio relic system, two isolated radio relics, a possible radio halo, disturbed V-shaped X-ray emission, and intr…
Abell 746: A highly disturbed cluster undergoing multiple mergers
K. Rajpurohit, L. Lovisari, A. Botteon +21
We present deep XMM-Newton, Karl Jansky Very Large Array, and upgraded Giant Metrewave Radio Telescope observations of Abell 746, a cluster that hosts a plethora of diffuse emissio…
Waking the monster: the onset of AGN feedback in galaxy clusters hosting young central radio galaxies
Francesco Ubertosi, Myriam Gitti, Fabrizio Brighenti +3
The investigation of the feedback cycle in galaxy clusters has historically been performed for systems where feedback is ongoing ("mature-feedback" clusters), that is where the cen…
Revisiting X-ray-Bright-Optically-Normal-Galaxies with the Chandra Source Catalog
Dong-Woo Kim, Amanda Malnati, Alyssa Cassity +3
X-ray bright optically normal galaxies (XBONGs) are galaxies with X-ray luminosities consistent with those of active galactic nuclei (AGNs) but no evidence of AGN optical emission…
