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…
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…
Effects of Varied Cosmic Ray Feedback from AGN on Massive Galaxy Properties
Charvi Goyal, Sam B. Ponnada, Philip F. Hopkins +3
Active galactic nuclei (AGN) provide energetic feedback necessary to `turn off' star formation in high-mass galaxies (M 10 M, $10.4 \leq \log(…
Fermi Bubbles Without AGN: Gamma-Ray Bubbles in MHD Galaxy Formation Simulations with Full Cosmic Ray Spectra
Isabel S. Sands, Philip F. Hopkins, Sam B. Ponnada
For the first time, we show in MHD simulations with cosmological initial conditions that bi-lobed gamma-ray outflows similar to the Fermi bubbles can form from star formation and s…
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…
Strong Evidence for Cosmic Ray-Supported L Galaxy Halos via X-ray \& tSZ Constraints
Sam B. Ponnada, Philip F. Hopkins, Yue Samuel Lu +3
Many state-of-the-art galaxy simulations featuring traditional feedback modes have significant challenges producing enough extended soft X-ray ( keV) emission at R $\si…
