The Advanced X-ray Imaging Satellite (AXIS) Community Science Book
Michael Koss, Nafisa Aftab, Steven W. Allen +395
The AXIS Community Science Book represents the collective effort of 592 scientists worldwide to define the transformative science enabled by the Advanced X-ray Imaging Satellite (A…
Multiphase gas offsets in the atmospheres of central galaxies and their consequences for SMBH activation I. The hot and warm ionized gas phases
Francesco Ubertosi, Fabrizio Brighenti, Ewan O'Sullivan +10
We investigate the spatial relationships between multi-phase gas components and supermassive black hole (SMBH) activity in a sample of 25 cool core galaxy groups and clusters. Usin…
JVLA and VLBA study of the merging cool core CHIPS 1911+4455 at z~0.5: radio emission from an infant AGN and from a rapidly star-forming BCG
Francesco Ubertosi, Myriam Gitti, Pasquale Temi +5
Recent studies of galaxy clusters found peculiar cases at the boundary between non-cool core and cool core systems. While unusual, these objects can help us understand the evolutio…
Chandra X-ray Observatory study of the X-ray emission of PKS 0023-26 and comparison with recent ALMA results
A. Siemiginowska, R. Morganti, G. Fabbiano +4
We present a deep high-resolution Chandra X-ray Observatory image data of a powerful compact radio source PKS 0023-26 associated with a quasar at redshift 0.322. The earlier studie…
Radial Profiles of Radio Halos in Massive Galaxy Clusters: Diffuse Giants Over 2 Mpc
K. Rajpurohit, A. Botteon, E. O'Sullivan +9
We present new, high frequency radio observations of the merging galaxy clusters PLCK G287.0+32.9, Abell 2744, and Bullet. These clusters are known to host Mpc scale sources,…
PSZ2 G181.06+48.47 II: radio analysis of a low-mass cluster with exceptionally-distant radio relics
Kamlesh Rajpurohit, Andra Stroe, Ewan O'Sullivan +13
We report upgraded Giant Metrewave Radio Telescope and Karl J. Jansky Very Large Array radio observations of a low-mass merging galaxy cluster PSZ2 G181.06+48.47. This exceptional…
Revisiting the Group-Dominant Elliptical NGC 5044 in the Radio Band: Continuum Emission and Detection of HI Absorption
Kamlesh Rajpurohit, Tirna Deb, Konstantinos Kolokythas +9
We present new MeerKAT L-band (continuum and HI) and upgraded Giant Metrewave Radio Telescope (300-850 MHz) observations of the archetypal cool-core group-dominant early-type galax…
PSZ2 G181.06+48.47 I: X-ray exploration of a low-mass cluster with exceptionally-distant radio relics
Andra Stroe, Kamlesh Rajpurohit, Zhenlin Zhu +13
Relics are diffuse, highly-polarized radio sources that trace merger-driven shocks at the periphery of merging galaxy clusters. The LOFAR survey recently discovered a rare example…
