Was the X-ray Afterglow of GRB 970815 Detected?
N. Mirabal, J. P. Halpern, E. V. Gotthelf +1
GRB 970815 was a well-localized gamma-ray burst (GRB) detected by the All-Sky Monitor (ASM) on the Rossi X-Ray Timing Explorer (RXTE) for which no afterglow was identified despite…
Imaging X-ray, Optical, and Infrared Observations of the Transient Anomalous X-ray Pulsar XTE J1810-197
E. V. Gotthelf, J. P. Halpern, M. Buxton +1
We report X-ray imaging, timing, and spectral studies of XTE J1810-197, a 5.54s pulsar discovered by Ibrahim et al. (2003) in recent RXTE observations. In a set of short exposures…
An X-ray Image of the Composite SNR G16.7+0.1
David J. Helfand, Marcel A. Agueros, E. V. Gotthelf
We have observed the Galactic supernova remnant G16.7+0.1 for 13 ks using the EPIC cameras aboard the XMM-Newton X-ray Observatory, producing the first X-ray image of the remnant.…
X-ray Spectra of Young Pulsars and Their Wind Nebulae: Dependence on Spin-down Energy
E. V. Gotthelf
An observational model is presented for the spectra of young rotation-powered pulsars and their nebulae based on a study of nine bright Crab-like pulsar systems observed with the C…
Search for a Point-Source Counterpart of the Unidentified Gamma-Ray Source TeV J2032+4130 in Cygnus
R. Mukherjee, J. P. Halpern, E. V. Gotthelf +2
We have made a multiwavelength study of the overlapping error boxes of the unidentified gamma-ray sources TeV J2032+4130 and 3EG J2033+4118 in the direction of the Cygnus OB2 assoc…
