3EG J2016+3657: Confirming an EGRET Blazar Behind the Galactic Plane
J. P. Halpern, M. Eracleous, R. Mukherjee +1
We recently identified the blazar-like radio source G74.87+1.22 (B2013+370) as the counterpart of the high-energy gamma-ray source 3EG J2016+3657 in the Galactic plane. However, si…
Detection of a Compact X-ray Source in the Supernova Remnant G29.6+0.1: A Variable Anomalous X-ray Pulsar?
G. Vasisht, E. V. Gotthelf, K. Torii +1
We present follow-up observations of the serendipitously discovered 7-s X-ray pulsar AX J1845-0258, which displays characteristics similar to those observed in the anomalous X-ray…
A 700 year-old Pulsar in the Supernova Remnant Kes 75
E. V. Gotthelf, G. Vasisht, M. Boylan-Kolchin +1
Since their discovery 30 years ago, pulsars have been understood to be neutron stars (NSs) born rotating rapidly (~ 10-100 ms). These neutron stars are thought to be created in sup…
The Vela Pulsar and its Synchrotron Nebula
D. J. Helfand, E. V. Gotthelf, J. P. Halpern
(Abridged) We present high-resolution Chandra X-ray observations of PSR B0833-45, the 89 ms pulsar associated with the Vela supernova remnant. We have acquired two observations sep…
A Possible X-ray and Radio Counterpart of the High-Energy Gamma-ray Source 3EG J2227+6122
J. P. Halpern, E. V. Gotthelf, K. M. Leighly +1
The identity of the persistent EGRET sources in the Galactic plane is largely a mystery. For one of these, 3EG J2227+6122, our complete census of X-ray and radio sources in its err…
Multiwavelength Examination of the COS-B Field 2CG 075+00 Yields a Blazar Identification for 3EG J2016+3657
R. Mukherjee, E. V. Gotthelf, J. Halpern +1
We present a high-energy study of the intriguing COS-B gamma-ray field, 2CG 075+00, in order to search for possible counterparts. New EGRET data show that the COS-B emission probab…
