The observed velocity distribution of young pulsars [PDF]

open access: yes, 2017
We argue that comparison with observations of theoretical models for the velocity distribution of pulsars must be done directly with the observed quantities, i.e. parallax and the two components of proper motion.

The Third Fermi Large Area Telescope Catalog of Gamma-Ray Pulsars

open access: yesThe Astrophysical Journal, 2023
We present 294 pulsars found in GeV data from the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope. Another 33 millisecond pulsars (MSPs) discovered in deep radio searches of LAT sources will likely reveal pulsations once phase-connected

Binary and Millisecond Pulsars [PDF]

open access: yesLiving Reviews in Relativity, 1998
Our knowledge of binary and millisecond pulsars has greatly increased in recent years. This is largely due to the success of large-area surveys which have brought the known population of such systems in the Galactic disk to around 50.

The NANOGrav 15 yr Data Set: Observations and Timing of 68 Millisecond Pulsars [PDF]

open access: yesAstrophysical Journal Letters, 2023
We present observations and timing analyses of 68 millisecond pulsars (MSPs) comprising the 15 yr data set of the North American Nanohertz Observatory for Gravitational Waves (NANOGrav).

FAST Globular Cluster Pulsar Survey: Twenty-four Pulsars Discovered in 15 Globular Clusters [PDF]

open access: yesAstrophysical Journal Letters, 2021
We present the discovery of 24 pulsars in 15 globular clusters (GCs) using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). These include the first pulsar discoveries in M2, M10, and M14.

The origin of single radio pulsars [PDF]

open access: yes, 1999
By comparing relative rates of supernovae versus formation rates of single radio pulsars, recycled pulsars, binary pulsars and X-ray binaries we put strong limits on the progenitors of radio pulsars and on the requirement of an asymmetry in the supernova.

Gravitational-wave Constraints on the Equatorial Ellipticity of Millisecond Pulsars [PDF]

open access: yesAstrophysical Journal Letters, 2020
We present a search for continuous gravitational waves from five radio pulsars, comprising three recycled pulsars (PSR J0437−4715, PSR J0711−6830, and PSR J0737−3039A) and two young pulsars: the Crab pulsar (J0534+2200) and the Vela pulsar (J0835−4510 ...

The Ups and Downs of Accreting X-Ray Pulsars: Decade-long Observations with the Fermi Gamma-Ray Burst Monitor [PDF]

open access: yesAstrophysical Journal, 2020
We review more than 10 yr of continuous monitoring of accreting X-ray pulsars with the all-sky Gamma-ray Burst Monitor (GBM) aboard the Fermi Gamma-ray Space Telescope.

Gamma Ray Pulsars and Opportunities for the MACE Telescope

open access: yesGalaxies, 2023
Rapidly rotating neutron stars with very strong surface magnetic fields are observed to emit pulsed emission in the whole range of electromagnetic spectrum from radio to high-energy gamma rays.

Extended gamma-ray sources around pulsars constrain the origin of the positron flux at Earth [PDF]

open access: yesScience, 2017
Exotic origin for cosmic positrons Several cosmic-ray detectors have found more positrons arriving at Earth than expected. Some researchers interpret this as a signature of exotic physics, such as the annihilation of dark matter particles.
