Classifying IGR J18007-4146 as an intermediate polar using XMM and NuSTAR
Benjamin M. Coughenour, John A. Tomsick, Aarran W. Shaw +5
Many new and unidentified Galactic sources have recently been revealed by ongoing hard X-ray surveys. A significant fraction of these have been shown to be the type of accreting wh…
Using Chandra Localizations and Gaia Distances and Proper Motions to Classify Hard X-ray Sources Discovered by INTEGRAL
John A. Tomsick, Benjamin M. Coughenour, Jeremy Hare +7
Here we report on X-ray observations of ten 17-60 keV sources discovered by the INTEGRAL satellite. The primary new information is sub-arcsecond positions obtained by the Chandra X…
Modeling the upper kHz QPOs of 4U 1728-34 with X-ray reverberation
Benjamin M. Coughenour, Edward M. Cackett, Philippe Peille +1
While kilohertz quasi-periodic oscillations (kHz QPOs) have been well studied for decades since their initial discovery, the cause of these signals remains unknown, as no model has…
NuSTAR Observations of the Accreting Atolls GX 3+1, 4U 1702-429, 4U 0614+091, and 4U 1746-371
R. M. Ludlam, J. M. Miller, D. Barret +7
Atoll sources are accreting neutron star (NS) low-mass X-ray binaries. We present a spectral analysis of four persistent atoll sources (GX 3+1, 4U 1702429, 4U 0614+091, and 4U 1…
