GeV emission around SS 433 with 17 years Fermi-LAT observation
Qiwang Sun, Dmitry Khangulyan, Jiren Liu +1
We present an analysis of 17 years of Fermi-LAT observations of the microquasar SS~433. We detect four GeV sources in the region: a newly identified source, PS J1910+0550, located…
Torque-dependent orbital modulation of X-ray pulsar Cen X-3
Zhenxuan Liao, Jiren Liu
Cen X-3 shows alternate spin-up/spin-down episodes lasting for tens of days. We study the orbital profiles and spectra of Cen X-3 during these spin-up/spin-down intervals, using lo…
The long-term spin-down trend of ultra-luminous X-ray pulsar M82 X-2
Jiren Liu
The discovery in 2014 of the pulsation from the ultra-luminous X-ray source (ULX) M82 X-2 in 2014 has changed our view of ULXs. Because of the relatively short baseline over which…
LAMOST J2043+3413 -- a Fast Disk Precession SW Sextans Candidate in Period Gap
Xin Li, Xiaofeng Wang, Jiren Liu +5
We present follow-up photometric observations and time-series analysis of a nova-like, SW Sextans-type, cataclysmic variable (CV) candidate, LAMOST J204305.95+341340.6 (here after…
The spin-down accretion regime of Galactic ultra-luminous X-ray pulsar Swift J0243.6+6124
Jiren Liu, Long Ji, MIngyu Ge
The relative high fluxes of the Galactic ultra-luminous X-ray pulsar Swift J0243 allow a detailed study of its spin-down regime in quiescence state, for a first time. After the 201…
Torque reversals and wind variations of X-ray pulsar Vela X-1
Zhenxuan Liao, Jiren Liu, Lijun Gou
The erratic spin history of Vela X-1 shows some continuous spin-up/spin-down trend over tens of days. We study the orbital profile and spectral property of Vela X-1 in these spin-u…
