The Virgo Cluster as a Case Study for Ancient Cosmic Ray Halos in Radio and X-rays
Philip F. Hopkins, Emily M. Silich, Jack Sayers +2
Virgo is the nearest cool core (CC) galaxy cluster, and is archetypal of the class of X-ray weak CCs. Despite the X-ray continuum implying a large cooling rate ($\gtrsim 10\,{\rm M…
Clusters Hiding Under Millimeter Sources (CHUMS) I: Extreme CHUMS
Harshda Saxena, Adam B. Mantz, Jack Sayers +2
Galaxy cluster abundance provides a powerful probe of the CDM model and enables precise constraints on cosmological parameters. Millimeter-wavelength surveys detect clusters thr…
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…
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…
Measuring the Temperature of Extremely Hot Shock-Heated Gas in the Major Merger MACS J0717.5+3745 With Relativistic Corrections to the Sunyaev-Zel'dovich Effect
Benjamin J. Vaughan, Jack Sayers, Locke Spencer +10
The conversion of gravitational potential to kinetic energy results in an intracluster medium (ICM) gas with a characteristic temperature near 10 keV in the most massive galaxy clu…
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…
Galaxy Cluster Scaling Relations between Bolocam Sunyaev-Zel'dovich Effect and Chandra X-ray Measurements
N. G. Czakon, J. Sayers, A. Mantz +11
We present scaling relations between the integrated Sunyaev-Zel'dovich Effect (SZE) signal, , its X-ray analogue, , and total mass…
