Rapid X-ray variations of the Geminga pulsar wind nebula
C. Y. Hui, Jongsu Lee, A. K. H. Kong +4
A recent study by Posselt et al. (2017) reported the deepest X-ray investigation of the Geminga pulsar wind nebula (PWN) by using \emph{Chandra X-ray Observatory}. In comparison wi…
Searching for High Energy, Horizon-scale Emissions from Galactic Black Hole Transients during Quiescence
Lupin Chun-Che Lin, Hung-Yi Pu, Kouichi Hirotani +5
We search for the gamma-ray counterparts of stellar-mass black holes using long-term Fermi archive to investigate the electrostatic acceleration of electrons and positrons in the v…
Mode change of a gamma-ray pulsar, PSR J2021+4026
J. Zhao, C. W. Ng, L. C. C. Lin +8
A glitch of a pulsar is known as a sudden increase in the spin frequency and spin-down rate (frequency time derivative), and it can be caused by a sudden rel\ ease of the stress bu…
Lepton acceleration in the vicinity of the event horizon: Very-high-energy emissions from super-massive black holes
Kouichi Hirotani, Hung-Yi Pu, Lupin Chun-Che Lin +5
Around a rapidly rotating black hole (BH), when the plasma accretion rate is much less than the Eddington rate, the radiatively inefficient accretion flow (RIAF) cannot supply enou…
Swift, XMM-Newton, and NuSTAR observations of PSR J2032+4127/MT91 213
K. L. Li, A. K. H. Kong, P. H. T. Tam +3
We report our recent Swift, NuSTAR, and XMM-Newton X-ray and Lijiang optical observations on PSR J2032+4127/MT91 213, the gamma-ray binary candidate with a period of 45-50 years. T…
Search for GeV counterparts to fast radio bursts with Fermi
Shao-Qiang Xi, Pak-Hin Thomas Tam, Fang-Kun Peng +1
The non-repeating fast radio bursts (FRBs) could arise from catastrophic stellar explosions or magnetar giant flares, so relativistic blast waves might be produced in these events.…
