NuSTAR Hard X-ray Survey of the Galactic Center Region I: Hard X-ray Morphology and Spectroscopy of the Diffuse Emission
Kaya Mori, Charles J. Hailey, Roman Krivonos +35
We present the first sub-arcminute images of the Galactic Center above 10 keV, obtained with NuSTAR. NuSTAR resolves the hard X-ray source IGR J17456-2901 into non-thermal X-ray fi…
Hard X-ray Morphological and Spectral Studies of The Galactic Center Molecular Cloud Sgr B2: Constraining Past Sgr A* Flaring Activity
Shuo Zhang, Charles J. Hailey, Kaya Mori +15
Galactic Center (GC) molecular cloud Sgr B2 is the best manifestation of an X-ray reflection nebula (XRN) reprocessing a past giant outburst from the supermassive black hole Sgr A*…
Statistics of X-ray flares of Sagittarius A*: evidence for solar-like self-organized criticality phenomenon
Ya-Ping Li, Feng Yuan, Qiang Yuan +6
X-ray flares have routinely been observed from the supermassive black hole, Sagittarius A (Sgr A), at our Galactic center. The nature of these flares remains largel…
A Sample of E+A Galaxy Candidates in LAMOST Data Released 2
Haifeng Yang, Ali Luo, Xiaoyan Chen +14
A sample of 70 E+A galaxies are selected from 37, 206 galaxies in the second data release (DR2) of Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) according to t…
A Luminous X-ray Flare From The Nucleus of The Dormant Bulgeless Spiral Galaxy NGC 247
Hua Feng, Luis C. Ho, Philip Kaaret +4
NGC 247 is a nearby late-type bulgeless spiral galaxy that contains an inactive nucleus. We report a serendipitous discovery of an X-ray flare from the galaxy center with a luminos…
