Getting Its Kicks: A VLBA Parallax for the Hyperfast Pulsar B1508+55
S. Chatterjee, W. H. T. Vlemmings, W. F. Brisken +7
The highest velocity neutron stars establish stringent constraints on natal kicks, asymmetries in supernova core collapse, and the evolution of close binary systems. Here we presen…
Pulsar Astrometry at the Microarcsecond Level
W. H. T. Vlemmings, S. Chatterjee, W. F. Brisken +12
Determination of pulsar parallaxes and proper motions addresses fundamental astrophysical questions. We have recently finished a VLBI astrometry project to determine the proper mot…
New Binary and Millisecond Pulsars from Arecibo Drift-Scan Searches
M. A. McLaughlin, D. R. Lorimer, D. J. Champion +6
We discuss four recycled pulsars found in Arecibo drift-scan searches. PSR J1944+0907 has a spin period of 5.2 ms and is isolated. The 5.8-ms pulsar J1453+19 may have a low-mass co…
Pulsar Parallaxes at 5 GHz with the Very Long Baseline Array
S. Chatterjee, J. M. Cordes, W. H. T. Vlemmings +3
We present the first pulsar parallaxes measured with phase-referenced pulsar VLBI observations at 5 GHz. Due to the steep spectra of pulsars, previous astrometric measurements have…
Smashing the Guitar: An Evolving Neutron Star Bow Shock
S. Chatterjee, J. M. Cordes
The Guitar nebula is a spectacular example of an H-alpha bow shock nebula produced by the interaction of a neutron star with its environment. The radio pulsar B2224+65 is traveling…
New Pulsars Discovered in Arecibo Drift-Scan Searches
M. A. McLaughlin, D. R. Lorimer, D. J. Champion +6
We report on new pulsars discovered in Arecibo drift-scan data. Processing of 2200 square degrees of data has resulted in the detection of 41 known and 12 new pulsars. New pulsars…
