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…
The Brightest Pulses in the Universe: Multifrequency Observations of the Crab Pulsar's Giant Pulses
J. M. Cordes, N. D. R. Bhat, T. H. Hankins +2
We analyze the Crab pulsar at ten frequencies from 0.43 to 8.8 GHz using data obtained at the Arecibo Observatory. Giant pulses occur only in the main and interpulse components man…
Searches for Giant Pulses from Extragalactic Pulsars
M. A. McLaughlin, J. M. Cordes
We discuss the giant-pulse phenomenon exhibited by pulsars and the distances to which giant pulses might be detected from extragalactic pulsars. We describe the conditions under wh…
Searches for Fast Radio Transients
J. M. Cordes, M. A. McLaughlin
We discuss optimal detection of fast radio transients from astrophysical objects while taking into account the effects of propagation through intervening ionized media, including d…
