Pulsar Wind Nebulae in EGRET Error Boxes
Mallory S. E. Roberts, Crystal L. Brogan, Bryan M. Gaensler +3
A remarkable number of pulsar wind nebulae (PWN) are coincident with EGRET gamma-ray sources. X-ray and radio imaging studies of unidentified EGRET sources have resulted in the dis…
Radio and X-ray Observations of PSR B0540-69
Simon Johnston, R. W. Romani, F. E. Marshall +1
PSR B0540-69 is one of a small handful of pulsars known to emit giant pulses and the only extra-galactic pulsar known to do so. We observed the pulsar for a total of 72 hr over a 6…
Ain't No Crab, PWN Got A Brand New Bag: Correlated radio and X-ray Structures in Pulsar Wind Nebulae
Mallory S. E. Roberts, Maxim Lyutikov, Bryan M. Gaensler +3
The traditional view of radio pulsar wind nebulae (PWN), encouraged by the Crab nebula's X-ray and radio morphologies, is that they are a result of the integrated history of their…
Q0906+6930: The Highest-Redshift Blazar
Roger W. Romani, David Sowards-Emmerd, Lincoln Greenhill +1
We report the discovery of a radio-loud flat-spectrum QSO at z=5.47 with properties similar to those of the EGRET gamma-ray blazars. This source is the brightest radio QSO at z>5,…
Pulsar Kicks: Spin and Kinematic Constraints
Roger W. Romani
It has been noted that the Crab and Vela pulsar proper motions lie along the symmetry axes of their wind nebulae. In an effort to promote this observation to a serious test of kick…
Blazar Counterparts for 3EG Sources at -40 < decl. < 0: Pushing South Through the Bulge
D. Sowards-Emmerd, R. W. Romani, P. F. Michelson +1
Supplementing existing survey data with VLA observations, we have extended ray counterpart identifications down to decl. = -40 using our Figure of Merit approach. We fi…
Observations of PSR J2021+3651 and its X-ray Pulsar Wind Nebula G75.2+0.1
J. W. T. Hessels, M. S. E. Roberts, S. M. Ransom +5
We present results from X-ray and radio observations of the recently discovered young Vela-like pulsar PSR J2021+3651, which is coincident with the EGRET gamma-ray source GeV 2020+…
