The 2-10 keV emission properties of PSR B1937+21
L. Nicastro, G. Cusumano, L. Kuiper +3
We present the results of a BeppoSAX observation of the fastest pulsar known: PSR B1937+21. The ~ 200 ks observation (78.5 (34) ks MECS (LECS) exposure times) allowed us to investi…
COMPTEL upper limits for the 56Co gamma-ray emission from SN1998bu
R. Georgii, S. Plüschke, R. Diehl +6
Supernova 1998bu in the galaxy M96 was observed by COMPTEL for a total of 88 days starting 17 days after the explosion. We searched for a signal in the 847 keV and 1238 keV lines o…
High resolution spatial and timing observations of millisecond pulsar PSR J0218+4232 with Chandra
L. Kuiper, W. Hermsen, F. Verbunt +3
We report on high-resolution spatial and timing results for binary millisecond pulsar PSR J0218+4232 obtained with the Chandra HRC-I and HRC-S in imaging mode. We found no indicati…
COMPTEL Observations of the Gamma-Ray Blazar PKS 1622-297
S. Zhang, W. Collmar, K. Bennett +7
We report results of observations and analyses on the gamma-ray blazar PKS 1622-297, with emphasis on the COMPTEL data (0.75 - 30 MeV) collected between April 1991 and November 199…
