Binary pulsar systems are superb probes of stellar and binary evolution and the physics of extreme environments. In a survey with the Arecibo telescope, we have found PSR J1903+032…
Discovery of a millisecond pulsar in the 5.4 day binary 3FGL J1417.5-4402: observing the late phase of pulsar recycling
F. Camilo, J. E. Reynolds, S. M. Ransom +8
In a search of the unidentified Fermi gamma-ray source 3FGL J1417.5-4402 with the Parkes radio telescope, we discovered PSR J1417-4402, a 2.66 ms pulsar having the same 5.4 day orb…
Hydrodynamical Backflow in X-shaped Radio Galaxy PKS 2014-55
W. D. Cotton, K. Thorat, J. J. Condon +13
We present MeerKAT 1.28 GHz total-intensity, polarization, and spectral-index images covering the giant (projected length ~Mpc) X-shaped radio source PKS~201455…
The Duck Redux: An Improved Proper Motion Upper Limit for the Pulsar B1757-24 Near the Supernova Remnant G5.4-1.2
J. A. Blazek, B. M. Gaensler, S. Chatterjee +3
"The Duck" is a complicated non-thermal radio system, consisting of the energetic radio pulsar B1757-24, its surrounding pulsar wind nebula G5.27-0.90 and the adjacent supernova re…
Timing of pulsars found in a deep Parkes multibeam survey
D. R. Lorimer, F. Camilo, M. A. McLaughlin
We have carried out a sensitive radio pulsar survey along the northern Galactic plane ( and $|b| \lapp 2^{\circ}$) using the Parkes 20-cm multibeam sys…
Arecibo and the ALFA Pulsar Survey
J. van Leeuwen, J. M. Cordes, D. R. Lorimer +34
The recently started Arecibo L-band Feed Array (ALFA) pulsar survey aims to find ~1000 new pulsars. Due to its high time and frequency resolution the survey is especially sensitive…
The Parkes multibeam pulsar survey: IV. Discovery of 180 pulsars and parameters for 281 previously known pulsars
G. Hobbs, A. Faulkner, I. H. Stairs +12
The Parkes multibeam pulsar survey has led to the discovery of more than 700 pulsars. In this paper, we provide timing solutions, flux densities and pulse profiles for 180 of these…
A MeerKAT look at the polarization of 47 Tucanae pulsars: magnetic field implications
F. Abbate, A. Possenti, A. Ridolfi +17
We present the polarization profiles of 22 pulsars in the globular cluster 47 Tucanae using observations from the MeerKAT radio telescope at UHF-band (544-1088 MHz) and report prec…
The magnetar 1E 1547.0-5408: radio spectrum, polarimetry, and timing
F. Camilo, J. Reynolds, S. Johnston +2
We have investigated the radio emission from the anomalous X-ray pulsar 1E 1547.0-5408 (PSR J1550-5418) using the Parkes telescope and the Australia Telescope Compact Array. The fl…
MeerKAT discovery of 13 new pulsars in Omega Centauri
W. Chen, P. C. C. Freire, A. Ridolfi +21
The most massive globular cluster in our Galaxy, Omega Centauri, is an interesting target for pulsar searches, because of its multiple stellar populations and the intriguing possib…
