Evidence for a moderate spin from X-ray reflection of the high-mass supermassive black hole in the cluster-hosted quasar H1821+643
Júlia Sisk-Reynés, Christopher S. Reynolds, James H. Matthews +1
We present an analysis of deep Low-Energy and High-Energy Transmission Grating archival observations of the extraordinarily luminous radio-quiet quasar H1821+643, hosted…
New constraints on light Axion-Like Particles using Chandra Transmission Grating Spectroscopy of the powerful cluster-hosted quasar H1821+643
Júlia Sisk Reynés, James H. Matthews, Christopher S. Reynolds +3
Axion-Like Particles (ALPs) are predicted by several Beyond the Standard Model theories, in particular, string theory. In the presence of an external magnetic field perpendicular t…
Probing the circumnuclear environment of NGC1275 with High-Resolution X-ray spectroscopy
Christopher S. Reynolds, Robyn N. Smith, Andrew C. Fabian +6
NGC1275 is the Brightest Cluster Galaxy (BCG) in the Perseus cluster and hosts the active galactic nucleus (AGN) that is heating the central 100\,kpc of the intracluster medium (IC…
