A hard look at local, optically-selected, obscured Seyfert galaxies
E. S. Kammoun, J. M. Miller, M. Koss +11
We study the X-ray spectra of a sample of 19 obscured, optically-selected Seyfert galaxies (Sy 1.8, 1.9 and 2) in the local universe (~Mpc), drawn from the CfA Seyfert…
Studying the Reflection Spectra of the New Black Hole X-ray Binary Candidate MAXI J1631-479 Observed by NuSTAR: A Variable Broad Iron Line Profile
Yanjun Xu, Fiona A. Harrison, John A. Tomsick +5
We present results from the Nuclear Spectroscopic Telescope Array (NuSTAR) observations of the new black hole X-ray binary candidate MAXI J1631-479 at two epochs during its 2018-20…
Multiwavelength Follow-up of the Hyperluminous Intermediate-mass Black Hole Candidate 3XMM J215022.4-055108
Dacheng Lin, Jay Strader, Aaron J. Romanowsky +6
We recently discovered the X-ray/optical outbursting source 3XMM J215022.4-055108. It was best explained as the tidal disruption of a star by an intermediate-mass black hole of mas…
Spectral evolution of the ultraluminous X-ray sources M82 X-1 and X-2
Murray Brightman, Dominic J. Walton, Yanjun Xu +5
M82 hosts two well-known ultraluminous X-ray sources (ULXs). X-1, an intermediate-mass black hole (IMBH) candidate, and X-2, an ultraluminous X-ray pulsar (ULXP). Here we present a…
