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…
NE2001. II. Using Radio Propagation Data to Construct a Model for the Galactic Distribution of Free Electrons
J. M. Cordes, T. J. W. Lazio
In Paper I we present a new model for the Galactic distribution of free electrons. In this paper we describe the input data and methodology for determining the structure and parame…
