Exploring the X-ray emission properties of the supernova remnant G67.7+1.8 and its central X-ray sources
C. Y. Hui, W. Becker
We have studied the supernova remnant G67.7+1.8 with the Chandra X-ray observatory. The remnant's X-ray morphology correlates well with the double-arc structure seen at radio wavel…
Resolving the bow-shock nebula around the old pulsar PSR B1929+10 with multi-epoch Chandra observations
C. Y. Hui, W. Becker
We have studied the nearby old pulsar PSR B1929+10 and its surrounding interstellar medium utilizing the sub-arcsecond angular resolution of the Chandra X-ray Observatory. The Chan…
Radio and X-ray nebulae associated with PSR J1509-5850
C. Y. Hui, W. Becker
We have discovered a long radio trail at 843 MHz which is apparently associated with middle age pulsar PSR J1509-5850. The radio trail has a length of ~7 arcmin. In X-rays, Chandra…
A search for X-ray counterparts of the millisecond pulsars in the globular cluster M28 (NGC 6626)
W. Becker, C. Y. Hui
A recent radio survey of globular clusters has increased the number of millisecond pulsars drastically. M28 is now the globular cluster with the third largest population of known p…
Discovery of an X-ray Nebula associated with PSR J2124-3358
C. Y. Hui, W. Becker
We report the discovery of an X-ray nebula associated with the nearby millisecond pulsar PSR J2124-3358. This is the first time that extended emission from a solitary millisecond p…
A Fast-Moving Central Compact Object in Puppis-A
C. Y. Hui, W. Becker
Utilizing two Chandra High Resolution Camera (HRC-I) observations with an epoch separation of somewhat more than five years, we have measured the proper motion of the central compa…
X-ray emission properties of the old pulsar PSR B2224+65
C. Y. Hui, W. Becker
Using archival Chandra data we studied the X-ray emission properties of PSR B2224+65 and its environment. Albeit limited by photon statistics the spectral analysis suggests that th…
Exploring the Central Compact Object in the RX J0852.0-4622 Supernova Remnant with XMM-Newton
W. Becker, C. Y. Hui, B. Aschenbach +1
The properties of the presumably young galactic supernova remnant (SNR) RX J0852.0-4622, discovered by ROSAT, are still uncertain. The data concerning the distance to the SNR, its…
Probing the Proper Motion of the Central Compact Object in Puppis-A with the Chandra High Resolution Camera
C. Y. Hui, W. Becker
By making use of the sub-arcsecond angular resolution of the High Resolution Camera (HRC-I) aboard the Chandra X-ray satellite we have examined the central compact object RX J0822-…
Searches for diffuse X-ray emission around millisecond pulsars: An X-ray nebula associated with PSR J2124-3358
C. Y. Hui, W. Becker
We report on diffuse X-ray emission associated with the nearby solitary millisecond pulsar PSR J2124-3358 detected with XMM-Newton and Chandra. The emission extends from the pulsar…
X-ray observations of RX J0822-4300 and Puppis-A
C. Y. Hui, W. Becker
Based on observations with the X-ray observatories Chandra and XMM-Newton we present results from a detailed spectro-imaging and timing analysis of the central compact X-ray source…
The Effects of Rotation on Thermal X-Ray Afterglows Resulting from Pulsar Glitches
C. Y. Hui, K. S. Cheng
We derive the anisotropic heat transport equation for rotating neutron stars and the thermal equilibrium condition in a relativistic rotating axisymmetric star is also derived thro…
Anisotropic Heat Transfer inside Rotating Neutron Stars
C. Y. Hui, K. S. Cheng
We have developed the anisotropic heat transport equation for rotating neutron stars. With a simple model of neutron star, we also model the propagation of heat pulses result from…
