Sub-second infrared variability from the archetypal accreting neutron star 4U~1728-34
F. M. Vincentelli, P. Casella, A. Borghese +23
We report on the first simultaneous high-time resolution X-ray and infrared (IR) observations of a neutron star low mass X-ray binary in its hard state. We performed h…
Long-Term X-Ray/UV Variability in ULXs
Norman Khan, Matthew. J. Middleton
The focus of NASA's Swift telescope has been transients and target-of-opportunity observing, resulting in many observations of ultraluminous X-ray sources (ULXs) over the last ~20…
The Luminous, Hard State Can't Be MAD
P. Chris Fragile, Koushik Chatterjee, Adam Ingram +1
We present a straightforward argument for why the luminous, hard state of black hole X-ray binaries (BHXRBs) cannot always be associated with a magnetically arrested accretion disc…
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…
Spectral calculations of 3D RMHD simulations of super-Eddington accretion onto a stellar-mass black hole
Brianna S. Mills, Shane W. Davis, Yan-Fei Jiang +1
We use the Athena++ Monte Carlo (MC) radiation transfer module to post-process simulation snapshots from non-relativistic Athena++ radiation magnetohydrodynamic (RMHD) simulations.…
Multiwavelength observations of the extraordinary accretion event AT2021lwx
P. Wiseman, Y. Wang, S. Hönig +43
We present observations from X-ray to mid-infrared wavelengths of the most energetic non-quasar transient ever observed, AT2021lwx. Our data show a single optical brightening by a…
