An Inverse-Compton-Boosted Cool Core Unifies Perseus's Radio and X-ray Halos
Philip F. Hopkins, Emily M. Silich, Jack Sayers +2
Perseus is the brightest X-ray strong cool-core (SCC) cluster, with a bright central radio and -ray source plus low-frequency radio mini and giant halos. It is the archetype of…
ICM-SHOX III. The case of MACS J0018.5+1626, a radio relic that looks like a radio halo?
P. Domínguez-Fernández, P. DomÃnguez-Fernández, J. A. ZuHone +10
We present the first detailed numerical modeling of the radio emission from MACS J0018.5+1626 as part of the Improved Constraints on Mergers with SZ, Hydrodynamical simulations, Op…
Observational Implications of Cosmic Ray-Inverse Compton 'Boosted' Cool Cores in Clusters
Philip F. Hopkins, Emily Silich, Jack Sayers +2
X-ray luminous cool-core (CC) galaxy clusters contain powerful cosmic ray (CR) sources. High-energy CRs powering GHz synchrotron lose energy rapidly, but long-lived (~Gyr-old) popu…
Exploring a cosmic ray inverse-Compton origin to the SZ-to-X-ray pressure deficit in the cool core cluster ZwCl 3146
Emily M. Silich, Jack Sayers, Philip F. Hopkins +4
We explore the possibility that inverse-Compton (IC) scattering of cosmic microwave background photons by GeV cosmic rays (CRs) injected by the central active galactic nucleu…
