X-ray flares from the stellar tidal disruption by a candidate supermassive black hole binary
Xinwen Shu, Wenjie Zhang, Shuo Li +8
Optical transient surveys have led to the discovery of dozens of stellar tidal disruption events (TDEs) by massive black hole in the centers of galaxies. Despite extensive searches…
X-ray reprocessing in accreting pulsar GX 301-2 observed with Insight-HXMT
L. Ji, V. Doroshenko, V. Suleimanov +100
We investigate the absorption and emission features in observations of GX 301-2 detected with Insight-HXMT/LE in 2017-2019. At different orbital phases, we found prominent Fe Kalph…
Insight-HXMT observations of a possible fast transition from jet to wind dominated state during a huge flare of GRS~1915+105
L. D. Kong, S. Zhang, Y. P. Chen +92
We present the analysis of the brightest flare that was recorded in the \emph{Insight}-HMXT data set, in a broad energy range (2200 keV) from the microquasar GRS~1915+105 during…
Physical origin of the nonphysical spin evolution of MAXI J1820+070
J. Guan, L. Tao, J. L. Qu +91
We report on the Insight-HXMT observations of the new black hole X-ray binary MAXI J1820+070 during its 2018 outburst. Detailed spectral analysis via the continuum fitting method s…
Efficient and Effective Community Search on Large-scale Bipartite Graphs
Kai Wang, Wenjie Zhang, Xuemin Lin +3
Bipartite graphs are widely used to model relationships between two types of entities. Community search retrieves densely connected subgraphs containing a query vertex, which has b…
A variable ionized disk wind in the black-hole candidate EXO 1846-031
Yanan Wang, Long Ji, Javier A. Garcia +88
After 34 years, the black-hole candidate EXO 1846-031 went into outburst again in 2019. We investigate its spectral properties in the hard intermediate and the soft states with NuS…
