Cluster Radio Halos at the crossroads between astrophysics and cosmology in the SKA era
R. Cassano, G. Bernardi, G. Brunetti +16
Giant Radio Halos (RH) are diffuse, Mpc-sized, synchrotron radio sources observed in a fraction of merging galaxy clusters. The current scenario for the origin of RHs assumes that…
The SKA view of cool-core clusters: evolution of radio mini-halos and AGN feedback
Myriam Gitti, Paolo Tozzi, Gianfranco Brunetti +10
In about 70% of the population of relaxed, cool-core galaxy clusters, the brightest cluster galaxy (BCG) is radio loud, showing non-thermal radio jets and lobes ejected by the cent…
Molecular Gas in the X-ray Bright Group NGC 5044 as Revealed by ALMA
Laurence P. David, Jeremy Lim, William Forman +17
A short 30 minute ALMA observation of the early-type galaxy NGC 5044, which resides at the center of an X-ray bright group with a moderate cooling flow, has detected 24 molecular s…
Deep Chandra Observations of HCG 16 - II. The Development of the Intra-group Medium in a Spiral-Rich Group
E. O'Sullivan, J. M. Vrtilek, L. P. David +6
We use a combination of deep Chandra X-ray observations and radio continuum imaging to investigate the origin and current state of the intra-group medium in the spiral-rich compact…
Deep Chandra Observations of HCG 16 - I. Active Nuclei, Star formation and Galactic Winds
E. O'Sullivan, A. Zezas, J. M. Vrtilek +6
We present new, deep Chandra X-ray and Giant Metrewave Radio Telescope 610~MHz observations of the spiral-galaxy-rich compact group HCG 16, which we use to examine nuclear activity…
Testing Secondary Models for the Origin of Radio Mini-Halos in Galaxy Clusters
John ZuHone, Gianfranco Brunetti, Simona Giacintucci +1
We present an MHD simulation of the emergence of a radio minihalo in a galaxy cluster core in a "secondary" model, where the source of the synchrotron-emitting electrons is hadroni…
