Effectiveness of Stacks in the Stacked Hilbert-Huang Transform
Lupin Chun-Che Lin, Chin-Ping Hu, Chien-Chang Yen +6
The Hilbert-Huang transform (HHT) consists of empirical mode decomposition (EMD), which is a template-free method that represents the combination of different intrinsic modes on a…
Investigation of gamma-ray variability and glitches of PSR J1420-6048
Lupin C. -C. Lin, H. H. Wang, C. Y. Hui +4
PSR J1420-6048 is a young gamma-ray pulsar with recurrent glitches. Utilizing long-term monitoring data obtained from the Fermi Gamma-ray Space Telescope, we found that PSR J1420-6…
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…
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…
Chandra and Swift X-ray Observations of the X-ray Pulsar SMC X-2 During the Outburst of 2015
K. L. Li, C. -P Hu, L. C. C. Lin +1
We report the Chandra/HRC-S and Swift/XRT observations for the 2015 outburst of the high-mass X-ray binary (HMXB) pulsar in the Small Magellanic Cloud, SMC X-2. While previous stud…
A Possible 55-day X-ray Period of the Ultraluminous Accreting Pulsar M82 X-2
A. K. H. Kong, C. -P. Hu, L. C. -C. Lin +4
We report a possible detection of a 55-day X-ray modulation for the ultraluminous accreting pulsar M82 X-2 from archival Chandra observations. Because M82 X-2 is known to have a 2.…
Long-term X-ray Variability of Ultraluminous X-ray Sources
L. C. -C. Lin, C. -P. Hu, A. K. H. Kong +3
Long-term X-ray modulations on timescales from tens to hundreds of days have been widely studied for X-ray binaries located in the Milky Way and the Magellanic Clouds. For other ne…
Searches for millisecond pulsar candidates among the unidentified Fermi objects
C. Y. Hui, S. M. Park, C. P. Hu +9
Here we report the results of searching millisecond pulsar (MSP) candidates from the Fermi LAT second source catalog (2FGL). Seven unassociated ray sources in this catalog are…
A detailed X-ray investigation of PSR J2021+4026 and -Cygni supernova remnant
C. Y. Hui, K. A. Seo, L. C. C. Lin +9
We have investigated the field around the radio-quiet -ray pulsar, PSR J2021+4026, with a ~140 ks XMM-Newton observation and a ~56 ks archival Chandra data. Through analyzing th…
Discovery of an ultracompact gamma-ray millisecond pulsar binary candidate
A. K. H. Kong, R. Jin, T. -C. Yen +8
We report multi-wavelength observations of the unidentified Fermi object 2FGL J1653.6-0159. With the help of high-resolution X-ray observation, we have identified an X-ray and opti…
Discovery of X-ray pulsations from "next Geminga" - PSR J1836+5925
L. C. C. Lin, C. Y. Hui, K. T. Li +5
We report the X-ray pulsation of ~173.3 ms for the "next Geminga", PSR J1836+5925, with recent XMM-Newton investigations. The X-ray periodicity is consistent wtih the gamma-ray eph…
Discovery of X-ray Pulsation from the Geminga-like Pulsar PSR J2021+4026
L. C. C. Lin, C. Y. Hui, C. P. Hu +8
We report the discovery of X-ray periodicity of ~265.3 ms from a deep XMM-Newton observation of the radio-quiet gamma-ray pulsar, PSR J2021+4026, located at the edge of the superno…
Detection of X-ray periodicity from a new eclipsing polar candidate XGPS-I J183251-100106
C. Y. Hui, K. A. Seo, C. P. Hu +2
We report the results from a detailed analysis of an archival XMM-Newton observation of the X-ray source XGPS-I J183251-100106, which has been suggested as a promising magnetic cat…
