Accretion disk wind of Hercules X-1 during the Short High state
P. Kosec, E. Kara, A. C. Fabian +5
Hercules X-1 is a nearly edge-on X-ray binary with a warped, precessing accretion disk, which manifests through a 35-day cycle of alternating High and Low flux states. This disk pr…
Digging a little deeper: characterising three new extreme ULX candidates
T. P. Roberts, D. J. Walton, A. D. A. Mackenzie +2
A prime motivation for compiling catalogues of any celestial X-ray source is to increase our numbers of rare sub-classes. In this work we take a recent multi-mission catalogue of u…
A new sample of transient ultraluminous X-ray sources serendipitously discovered by Swift/XRT
Murray Brightman, Jean-Marie Hameury, Jean-Pierre Lasota +11
Ultraluminous X-ray sources (ULXs) are our best laboratories for studying extreme super-Eddington accretion. Most studies of these objects are of relatively persistent sources, how…
Vertical wind structure in an X-ray binary revealed by a precessing accretion disk
P. Kosec, E. Kara, A. C. Fabian +11
The accretion of matter onto black holes and neutron stars often leads to the launching of outflows that can greatly affect the environments surrounding the compact object. In supe…
NuSTAR Observations of Candidate Subparsec Binary Supermassive Black Holes
M. Lynne Saade, Murray Brightman, Daniel Stern +12
We present analysis of NuSTAR X-ray observations of three AGN that were identified as candidate subparsec binary supermassive black hole (SMBH) systems in the Catalina Real-Time Tr…
Transient obscuration event captured in NGC 3227 IV. Origin of the obscuring cloud variability
S. Grafton-Waters, J. Mao, M. Mehdipour +13
Obscuration events in type I active galactic nuclei (AGN) have been detected more frequently in recent years. The strong flux decrease in the soft X-ray band between observations h…
