NuSTAR and XMM-Newton observations of the Arches cluster in 2015: fading hard X-ray emission from the molecular cloud
Roman Krivonos, Maica Clavel, JaeSub Hong +6
We present results of long NuSTAR (200 ks) and XMM-Newton (100 ks) observations of the Arches stellar cluster, a source of bright thermal (kT~2 keV) X-rays with prominent Fe XXV K_…
Imaging Analysis of the Hard X-ray Telescope ProtoEXIST2 and New Techniques for High Resolution Coded Aperture Telescopes
Jaesub Hong, Branden Allen, Jonathan Grindlay +1
Wide-field (> 100 deg) hard X-ray coded-aperture telescopes with high angular resolution (< 2') will enable a wide range of time domain astrophysics. For instance, transient so…
Evidence for intermediate polars as the origin of the Galactic Center hard X-ray emission
Charles J. Hailey, Kaya Mori, Kerstin Perez +14
Recently, unresolved hard (20-40 keV) X-ray emission has been discovered within the central 10 pc of the Galaxy, possibly indicating a large population of intermediate polars (IPs)…
NuSTAR Hard X-ray Survey of the Galactic Center Region II: X-ray Point Sources
JaeSub Hong, Kaya Mori, Charles J. Hailey +41
We present the first survey results of hard X-ray point sources in the Galactic Center (GC) region by NuSTAR. We have discovered 70 hard (3-79 keV) X-ray point sources in a 0.6 deg…
SXP214, an X-ray Pulsar in the Small Magellanic Cloud, Crossing the Circumstellar Disk of the Companion
JaeSub Hong, Vallia Antoniou, Andreas Zezas +12
Located in the Small Magellanic Cloud (SMC), SXP214 is an X-ray pulsar in a high mass X-ray binary system with a Be-star companion. A recent survey of the SMC under a Chandra X-ray…
Miniature lightweight x-ray optics (MiXO) for surface elemental composition mapping of asteroids and comets
Jaesub Hong, Suzanne Romaine, the MiXO team
The compositions of diverse planetary bodies are of fundamental interest to planetary science, providing clues to the formation and evolutionary history of the target bodies and th…
