CHANG-ES XXIX: The Sub-kpc Nuclear Bubble of NGC 4438
Jiang-Tao Li, Q. Daniel Wang, Theresa Wiegert +8
AGN bubbles could play an important role in accelerating high-energy CRs and galactic feedback. Only in nearby galaxies could we have high enough angular resolution in multi-wavele…
Joint Fit of Warm Absorbers in COS & HETG Spectra of NGC 3783
Xiao-Dan Fu, Shui-Nai Zhang, Wei Sun +2
Warm Absorbers (WAs), as an important form of AGN outflows, show absorption in both UV and X-ray band. Using XSTAR generated photoionization models, for the first time we present a…
Disc-corona interaction in the heartbeat state of GRS 1915+105
Shu-Ping Yan, Li Ji, Si-Ming Liu +10
Timing analysis provides information about the dynamics of matter accreting on to neutron stars and black holes, and hence is crucial for studying the physics of the accretion flow…
A timing view of the heartbeat state of GRS 1915+105
Shu-Ping Yan, Li Ji, Mariano Méndez +10
We present a timing analysis of two Rossi X-ray Timing Explorer observations of the microquasar GRS 1915+105 during the heartbeat state. The phase-frequency-power maps show that th…
Discovery of the transient magnetar 3XMM J185246.6+003317 near supernova remnant Kesteven 79 with XMM-Newton
Ping Zhou, Yang Chen, Xiang-Dong Li +5
We report the serendipitous discovery with XMM-Newton that 3XMM J185246.6+003317 is an 11.56 s X-ray pulsar located 1' away from the southern boundary of supernova remnant Kes 79.…
Giant H II Regions in M101. I. X-ray Analysis of Hot Gas
Wei Sun, Yang Chen, Li Feng +4
We performed a Chandra X-ray study of three giant H II regions (GHRs), NGC 5461, NGC 5462, and NGC 5471, in the spiral galaxy M101. The X-ray spectra of the three GHRs all contain…
