XMM-Newton and Swift Unveil Another X-Ray Transient in NGC 4945, XMM J130514.64-493311.27
Ryan W. Pfeifle, Kimberly A. Weaver, Jenna M. Cann +2
NGC 4945 hosts a Compton-thick, low luminosity AGN and a nuclear starburst in its core and has been the subject of many previous X-ray investigations of the AGN emission structure,…
The Hunt for Red Dual AGNs I: Spatially-Resolved Mid-IR Dual AGNs in the DeCam Legacy Survey
Ryan W. Pfeifle, Kimberly A. Weaver, Barry Rothberg +13
Theoretical studies predict that dual AGNs are a critical stage of galaxy merger-driven supermassive black hole growth. Systematic searches for dual AGNs typically target late-stag…
McFACTS. IV. Electromagnetic Counterparts to AGN-disk-embedded Binary Black Hole Mergers
Emily McPike, Rosalba Perna, K. E. Saavik Ford +10
The accretion disks of active galactic nuclei (AGNs) are promising environments for producing binary black hole (BBH) mergers, which have been detected via gravitational waves (GWs…
The Need for Ultra High Resolution X-ray Imaging
Kimberly A. Weaver, Jenna M. Cann, Ryan Pfeifle +20
This paper discusses the broad science case for obtaining milliarcsecond to microarcsecond astronomical imaging resolution in the soft to medium-energy X-ray band (~0.5 to ~8 keV).…
