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…
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…
The Chandra Source Catalog Normal Galaxy Sample
Dong-Woo Kim, Alyssa Cassity, Binod Bhatt +4
We present an extensive and well-characterized Chandra X-ray Galaxy Catalog (CGC) of 8557 galaxy candidates in the redshift range z ~ 0.04 - 0.7, optical luminosity 1010 - 1011 Lro…
Feedback in the merging galaxy group NGC6338
Gerrit Schellenberger, Ewan O'Sullivan, Simona Giacintucci +6
The galaxy group NGC6338 is one of the most violent group-group mergers known to date. While the central dominant galaxies rush at each other at 1400km/s along the line of sight, w…
Multi-phase gas interactions on subarcsec scales in the shocked IGM of Stephan's Quintet with JWST and ALMA
P. N. Appleton, P. Guillard, B. Emonts +12
We combine JWST and HST imaging with ALMA~CO(2-1) spectroscopy to study the highly turbulent multi-phase intergalactic medium (IGM) in Stephan's Quintet on 25-150 pc scales. Previo…
