Radio jet-ISM interaction and positive radio-mechanical feedback in Abell 1795
Prathamesh D. Tamhane, Brian R. McNamara, Helen R. Russell +8
We present XSHOOTER observations with previous ALMA, MUSE and observations to study the nature of radio-jet triggered star formation and the interaction of radio jets with th…
Does absorption against AGN reveal supermassive black hole accretion?
Tom Rose, B. R. McNamara, F. Combes +7
Galaxies often contain large reservoirs of molecular gas which shape their evolution. This can be through cooling of the gas -- which leads to star formation, or accretion onto the…
Molecular Flows in Contemporary Active Galaxies and the Efficacy of Radio-Mechanical Feedback
Prathamesh D. Tamhane, Brian R. McNamara, Helen R. Russell +4
Molecular gas flows are analyzed in 14 cluster galaxies (BCGs) centered in cooling hot atmospheres. The BCGs contain of molecular gas, much of which is…
Testing the Limits of AGN Feedback and the Onset of Thermal Instability in the Most Rapidly Star Forming Brightest Cluster Galaxies
Michael S. Calzadilla, Michael McDonald, Megan Donahue +8
We present new, deep, narrow- and broad-band Hubble Space Telescope observations of seven of the most star-forming brightest cluster galaxies (BCGs). Continuum-subtracted [O II] ma…
The structure of cluster merger shocks: turbulent width and the electron heating timescale
H. R. Russell, P. E. J. Nulsen, D. Caprioli +10
We present a new 2 Ms Chandra observation of the cluster merger Abell 2146, which hosts two huge M~2 shock fronts each ~500 kpc across. For the first time, we resolve and measure t…
The velocity structure of the Intracluster Medium of the Centaurus cluster
E. Gatuzz, J. S. Sanders, R. Canning +7
There are few direct measurements of ICM velocity structure, despite its importance for understanding clusters. We present a detailed analysis of the velocity structure of the Cent…
Turbulent magnetic fields in merging clusters: A case study of Abell 2146
Urmila Chadayammuri, John ZuHone, Paul Nulsen +2
Kelvin-Helmholtz Instabilities (KHI) along contact discontinuities in galaxy clusters have been used to constrain the strength of magnetic fields in galaxy clusters, following the…
