From Pulsar Spin to Pulsar Wind: The Spectral Connection?
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…
Multiwavelength Searches of Unidentified EGRET Sources
N. Mirabal, J. Halpern, R. Mukherjee +2
3EG J1835+5918 is the brightest of the so-called unidentified EGRET sources at intermediate galactic latitude (l,b)=(89,25). We obtained complete radio, optical, and X-ray coverage…
On the Nature of the X-ray Emission from the Galactic Center Region
Q. D. Wang, E. V. Gotthelf, C. C. Lang
The origin of the X-ray emission from the central region of the Galaxy has remained a mystery, despite extensive study over the past two decades. A fundamental question is the rela…
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…
