The Pulsar Population in Globular Clusters and in the Galaxy
Paulo C. C. Freire
In this paper, I review some of the basic properties of the pulsar population in globular clusters (GCs) and compare it with the the Galactic disk population. The neutron stars (NS…
The relativistic pulsar-white dwarf binary PSR J1738+0333 II. The most stringent test of scalar-tensor gravity
Paulo C. C. Freire, Norbert Wex, Gilles Esposito-Farèse +7
(abridged) We report the results of a 10-year timing campaign on PSR J1738+0333, a 5.85-ms pulsar in a low-eccentricity 8.5-hour orbit with a low-mass white dwarf companion (...) T…
Radio and Gamma-Ray Constraints on the Emission Geometry and Birthplace of PSR J2043+2740
A. Noutsos, A. A. Abdo, M. Ackermann +146
We report on the first year of Fermi gamma-ray observations of pulsed high-energy emission from the old PSR J2043+2740. The study of the gamma-ray efficiency of such old pulsars gi…
Pulsar Discovery by Global Volunteer Computing
B. Knispel, B. Allen, J. M. Cordes +37
Einstein@Home aggregates the computer power of hundreds of thousands of volunteers from 192 countries to "mine" large data sets. It has now found a 40.8 Hz isolated pulsar in radio…
The Deceptively Boring PSR J1738+0333
Paulo Freire, Norbert Wex
We present preliminary results of 7 years of Arecibo timing of the pulsar-white dwarf binary PSR J1738+0333. We can measure the proper motion, parallax with excellent precision and…
Radio detection of LAT PSRs J1741-2054 and J2032+4127: no longer just gamma-ray pulsars
F. Camilo, P. S. Ray, S. M. Ransom +24
Sixteen pulsars have been discovered so far in blind searches of photons collected with the Large Area Telescope on the Fermi Gamma-ray Space Telescope. We here report the discover…
