A comparison of millisecond pulsar populations between globular clusters and the Galactic field
Jongsu Lee, C. Y. Hui, J. Takata +4
We have performed a systematic study of the rotational, orbital and X-ray properties of millisecond pulsars (MSPs) in globular clusters (GCs) and compared their nature with those o…
A deep X-ray spectral imaging of the bow-shock pulsar wind nebula associated with PSR B1929+10
Sangin Kim, C. Y. Hui, Jongsu Lee +3
In this work, we study the X-ray bow-shock nebula powered by the mature pulsar PSR B1929+10 using data from XMM-Newton, with an effective exposure of 300 ks, offering the de…
Searches for Pulsar-like Candidates from Unidentified Objects in the Third Catalog of Hard Fermi-LAT (3FHL) sources with Machine Learning Techniques
C. Y. Hui, Jongsu Lee, K. L. Li +7
We report the results of searching pulsar-like candidates from the unidentified objects in the Catalog of Hard Fermi-LAT sources (3FHL). Using a machine-learning based…
Face changing companion of the redback millisecond pulsar PSR J1048+2339
Yee Xuan Yap, K. L. Li, A. K. H. Kong +3
We present optical observations of the redback millisecond pulsar PSR J1048+2339, which is a 4.66 ms radio pulsar in a compact binary with an orbital period of six hours. We obtain…
Discovery of an X-ray nebula in the field of millisecond pulsar PSR J1911-1114
Jongsu Lee, C. Y. Hui, J. Takata +1
We have discovered an extended X-ray feature which is apparently associated with millisecond pulsar (MSP) PSR J1911-1114 from a XMM-Newton observation, which extends for ~1' and th…
X-ray Census of Millisecond Pulsars in the Galactic field
Jongsu Lee, C. Y. Hui, J. Takata +3
We have conducted a systematic survey for the X-ray properties of millisecond pulsars (MSPs). Currently, there are 47 MSPs with confirmed X-ray detections. We have also placed the…
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…
Differences between radio-loud and radio-quiet gamma-ray pulsars as revealed by Fermi
C. Y. Hui, Jongsu Lee, J. Takata +2
By comparing the properties of non-recycled radio-loud ray pulsars and radio-quiet ray pulsars, we have searched for the differences between these two populations. We found…
