X-ray Coronal Properties of Swift/BAT-Selected Seyfert 1 Active Galactic Nuclei

Kavli Affiliate: Claudio Ricci | First 5 Authors: Nikita Kamraj, Murray Brightman, Fiona A. Harrison, Daniel Stern, Javier A. García | Summary: The corona is an integral component of Active Galactic Nuclei (AGN) which produces the bulk of the X-ray emission above 1–2 keV. However, many of its physical properties and the mechanisms powering this […]

X-ray morphology of cluster-mass haloes in self-interacting dark matter

Kavli Affiliate: Steven W. Allen | First 5 Authors: Xuejian Shen, Thejs Brinckmann, David Rapetti, Mark Vogelsberger, Adam Mantz | Summary: We perform cosmological zoom-in simulations of $19$ relaxed cluster-mass haloes with the inclusion of adiabatic gas within the cold dark matter (CDM) and self-interacting dark matter (SIDM) models. These clusters are selected as dynamically […]

Precisely computing bound orbits of spinning bodies around black holes I: General framework and results for nearly equatorial orbits

Kavli Affiliate: Scott A. Hughes | First 5 Authors: Lisa V. Drummond, Scott A. Hughes, , , | Summary: Very large mass ratio binary black hole systems are of interest both as a clean limit of the two-body problem in general relativity, as well as for their importance as sources of low-frequency gravitational waves. At […]
