Classification of IGR J20084+3221 as an Intermediate Polar using X-ray and Optical Observations
Julian Gerber, Jeremy Hare, John A. Tomsick +2
IGR J20084+3221 is a previously unclassified Galactic source first detected by INTEGRAL. Chandra observations led to possible classifications of either a magnetic Cataclysmic Varia…
Investigating MAXI J1752-457 with NuSTAR in the aftermath of a superburst
Sean N. Pike, Hitoshi Negoro, Douglas Buisson +5
We present two NuSTAR observations of the X-ray transient, MAXI J1752-457, following a superburst which was observed by MAXI/GSC in November, 2024. NuSTAR follow-up confirmed that…
Hunting for High-Mass X-ray Binaries in the Galactic Center with NuSTAR
Shifra Mandel, Julian Gerber, Kaya Mori +9
The central deg region of our Galaxy contains X-ray point sources that were detected by a series of Chandra observations over the last two decades. Ho…
X-ray measurement of a high-mass white dwarf and its spin for the intermediate polar IGR J18434-0508
Julian Gerber, Jeremy Hare, John A. Tomsick +8
IGR J18434-0508 is a Galactic Intermediate Polar (IP) type Cataclysmic Variable (CV) previously classified through optical spectroscopy. The source is already known to have a hard…
The High Energy X-ray Probe (HEX-P): resolving the nature of Sgr A* flares, compact object binaries and diffuse X-ray emission in the Galactic Center and beyond
Kaya Mori, Gabriele Ponti, Matteo Bachetti +24
HEX-P is a probe-class mission concept that will combine high spatial resolution X-ray imaging ( FWHM) and broad spectral coverage (0.2-80 keV) with an effective area far sup…
Constraining white dwarf mass and magnetic field strength of a new intermediate polar through X-ray observations
Benjamin Vermette, Ciro Salcedo, Kaya Mori +9
We report a broad-band analysis of a Galactic X-ray source, CXOGBS J174517.0-321356 (J1745), with a 614-second periodicity. Chandra discovered the source in the direction of the Ga…
