Rapid Mid-Infrared Spectral-Timing with JWST. I. The prototypical black hole X-ray Binary GRS 1915+105 during a MIR-bright and X-ray-obscured state

P. Gandhi, E. S. Borowski, J. Byrom +44

We present mid-infrared (MIR) spectral-timing measurements of the prototypical Galactic microquasar GRS 1915+105. The source was observed with the Mid-Infrared Instrument (MIRI) on…

Extreme Quiescent Variability of the Transient Neutron Star Low-mass X-ray Binary EXO 1745-248 in Terzan 5

L. E. Rivera Sandoval, R. Wijnands, N. Degenaar +9

EXO 1745-248 is a transient neutron-star low-mass X-ray binary that resides in the globular cluster Terzan 5. We studied the transient during its quiescent state using 18 Chandra o…

Mid-UV Studies of the Transitional Millisecond Pulsars XSS J12270-4859 and PSR J1023+0038 During Their Radio Pulsar States

L. E. Rivera Sandoval, J. V. Hernandez Santisteban, N. Degenaar +7

We report mid-UV (MUV) observations taken with HST/WFC3, Swift/UVOT and GALEX/NUV of the transitional millisecond pulsars XSS J12270-4859 and PSR J1023+0038 during their radio puls…

Constraining the properties of neutron star crusts with the transient low-mass X-ray binary Aql X-1

A. C. Waterhouse, N. Degenaar, R. Wijnands +4

Aql X-1 is a prolific transient neutron star low-mass X-ray binary that exhibits an accretion outburst approximately once every year. Whether the thermal X-rays detected in interve…

A Chandra/HETGS Census of X-ray Variability From Sgr A* During 2012

J. Neilsen, M. A. Nowak, C. Gammie +13

We present the first systematic analysis of the X-ray variability of Sgr A* during the Chandra X-ray Observatory's 2012 Sgr A* X-ray Visionary Project (XVP). With 38 High Energy Tr…

A search for iron emission lines in the Chandra X-ray spectra of neutron star low-mass X-ray binaries

E. M. Cackett, J. M. Miller, J. Homan +6

While iron emission lines are well studied in black hole systems, both in X-ray binaries and Active Galactic Nuclei, there has been less of a focus on these lines in neutron star l…

X-ray states and radio emission in the black hole candidate XTE J1550-564

S. Corbel, P. Kaaret, R. K. Jain +8

We report on radio and X-ray observations of the black hole candidate (BHC) XTE J1550-564 performed during its 2000 X-ray outburst. Observations have been conducted with the Austra…
