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…

Cosmic Rays Masquerading as Cool Cores: An Inverse-Compton Origin for Cool Core Cluster Emission
Philip F. Hopkins, Eliot Quataert, Emily M. Silich +3
X-ray bright cool-core (CC) clusters contain luminous radio sources accelerating cosmic ray (CR) leptons at prodigious rates. Near the acceleration region, high-energy leptons prod…
