Eight new MSPs in NGC 6440 and NGC 6441
Paulo C. C. Freire, Scott M. Ransom, Steve Begin +4
We report the discovery of five new millisecond pulsars in the globular cluster NGC 6440 and three new ones in NGC 6441; each cluster has one previously known pulsar. Four of the n…
Observed luminosity difference between isolated and binary MSPs
A. N. Lommen, R. A. Kipphorn, D. J. Nice +3
We perform a brief census of velocities of isolated versus binary millisecond pulsars. We find the velocities of the two populations are indistinguishable. However, the scale heigh…
GBT Observations of Very Low Mass Binary Millisecond Pulsars: A Search for Eclipses
David J. Nice, Ingrid H. Stairs, Zaven Arzoumanian
We searched for eclipses of two millisecond pulsars, PSR J1807-2459 and PSR B1908+00. These pulsars are in very low mass binary systems with orbital parameters similar to those of…
Arecibo Measurements of Pulsar--White Dwarf Binaries: Evidence for Heavy Neutron Stars
David J. Nice, Eric M. Splaver, Ingrid H. Stairs
We summarize constraints on neutron star masses from ongoing timing observations of pulsar-white dwarf binaries at Arecibo. The trend is toward pulsar masses larger than the canoni…
A 20-cm Survey for Pulsars in Globular Clusters using the GBT and Arecibo
Scott Ransom, Jason Hessels, Ingrid Stairs +3
We have been conducting deep searches at ~20 cm of >30 globular clusters (GCs) using the 305-m Arecibo telescope in Puerto Rico and the 100-m Green Bank telescope (GBT) in West Vir…
A 20 cm Search for Pulsars in Globular Clusters with Arecibo and the GBT
Jason W. T. Hessels, Scott M. Ransom, Ingrid H. Stairs +4
We are conducting deep searches for radio pulsations at L-band (~ 20cm) towards more than 30 globular clusters using the 305m Arecibo telescope in Puerto Rico and the 100m Green Ba…
