Cosmic distributions of stellar tidal disruptions by massive black holes at galactic centers
Yunfeng Chen, Qingjuan Yu, Youjun Lu
Stars can be consumed (either tidally disrupted or swallowed whole) by massive black holes (MBHs) at galactic centers when they move into the vicinity of the MBHs. In this study, w…

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…
Estimating the black hole spin for the X-ray binary MAXI J1820+070
Xueshan Zhao, Lijun Gou, Yanting Dong +6
MAXI J1820+070 is a newly-discovered black hole X-ray binary, whose dynamical parameters, namely the black hole mass, the inclination angle and the source distance, have been estim…
The Awakening Beast in the Seyfert 1 Galaxy KUG 1141+371 I
Jiachen Jiang, Huaqing Cheng, Luigi C. Gallo +10
KUG 1141+371 is a Seyfert 1 galaxy that shows a simultaneous flux increase in the optical and UV bands in the past decade. For instance, the latest Swift observation in 2019 shows…
Wideband Monitoring Observations of PSR J1803-3002A in the Globular Cluster NGC 6522
Lei Zhang, Richard N. Manchester, Andrew D. Cameron +10
We report the first wideband monitoring observations of PSR J1803-3002A, a relatively bright millisecond pulsar in the globular cluster NGC 6522 with a spin period of 7.1 ms and no…
Possible ~0.4 hour X-ray quasi-periodicity from an ultrasoft active galactic nucleus
J. R. Song, X. W. Shu, L. M. Sun +6
RX J1301.9+2747 is an ultrasoft active galactic nucleus (AGN) with unusual X-ray variability that is characterized by a long quiescent state and a short-lived flare state. The X-ra…
Precession of triaxially deformed neutron stars
Yong Gao, Lijing Shao
A deformed neutron star (NS) will precess if the instantaneous spin axis and the angular momentum are not aligned. Such a precession can produce continuous gravitational waves (GWs…
Fast radio bursts: do repeaters and non-repeaters originate in statistically similar ensembles
Xiang-Han Cui, Cheng-Min Zhang, Shuang-Qiang Wang +9
Fast Radio Bursts (FRBs) are the short, strong radio pulses lasting several milliseconds. They are subsequently identified, for the most part, as emanating from unknown objects at…
Exploring the origin of stars on bound and unbound orbits causing tidal disruption events
