X-ray Detection of PSR 1757-24 and its Nebular Tail
V. M. Kaspi, E. V. Gotthelf, B. M. Gaensler +1
We report the first X-ray detection of the radio pulsar PSR B1757-24 using the Chandra X-ray Observatory. The image reveals point-source emission at the pulsar position, consistent…
Chandra Spectroscopy of Pulsars and their Wind Nebulae
E. V. Gotthelf, C. M. Olbert
We present preliminary results from a systematic spectral study of pulsars and their wind nebulae using the Chandra X-Ray Observatory. The superb spatial resolution of Chandra allo…
Chandra X-ray Spectroscopy of Kes75, its Young Pulsar, and its Synchrotron Nebula
B. F. Collins, E. V. Gotthelf, D. J. Helfand
We have observed the young Galactic supernova remnant Kes 75 with the Chandra X-ray Observatory. This object is one of an increasing number of examples of a shell-type remnant with…
Hiccups in the night: X-ray monitoring of the two Crab-like LMC pulsars
E. V. Gotthelf, W. Zhang, F. E. Marshall +2
We are undertaking an extensive X-ray monitoring campaign of the two Crab-like pulsars in the Large Magellanic Clouds, PSR B0540-69 and PSR J0537-6910. We present our current phase…
15 Years Going Steady - Timing the Magnetar 1E 1841-045
E. V. Gotthelf, F. P. Gavriil, V. M. Kaspi +2
We report on a long-term monitoring campaign of 1E 1841-045, the 12-s anomalous X-ray pulsar and magnetar candidate at the center of the supernova remnant Kes 73. We have obtained…
The New Gamma-ray Pulsar PSR J2229+6114, its Pulsar Wind Nebula, and Comparison with the Vela Pulsar
J. P. Halpern, E. V. Gotthelf, F. Camilo +2
With a period of 51.6 ms and spin-down power 2.2x10^{37} erg s^{-1}, PSR J2229+6114 is a compelling identification for the EGRET source 3EG J2227+6122 in which error circle it resi…
