A non-thermal pulsed X-ray emission of AR~Scorpii
J. Takata, C. -P. Hu, L. C. C. Lin +5
We report the analysis result of UV/X-ray emission from AR~Scorpii, which is an intermediate polar (IP) composed of a magnetic white dwarf and a M-type star, with the XMM-Newton da…
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…
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…
A NuSTAR Observation of the Gamma-ray Emitting Millisecond Pulsar PSR J1723-2837
A. K. H. Kong, C. Y. Hui, J. Takata +2
We report on the first NuSTAR observation of the gamma-ray emitting millisecond pulsar binary PSR J1723-2837. X-ray radiation up to 79 keV is clearly detected and the simultaneous…
Gamma-ray Emission of the Kes 73/1E 1841-045 Region Observed with the Fermi Large Area Telescope
Paul K. H. Yeung, Albert K. H. Kong, P. H. Thomas Tam +3
The supernova remnant Kes 73 and/or the magnetar 1E 1841-045 at its center can deposit a large amount of energy to the surroundings and is potentially responsible for particle acce…
High-Energy emissions from the Pulsar/Be binary system PSR J2032+4127/MT91 213
J. Takata, P. H. T. Tam, C. W. Ng +4
PSR J2032+4127 is a radio-loud gamma-ray-emitting pulsar; it is orbiting around a high-mass Be type star with a very long orbital period of 25-50years, and is approaching periastro…
