The Astrophysical JournalWe have searched for radio pulsations toward 49 Fermi Large Area Telescope (LAT) 1FGL Catalog γ -ray sources using the Green Bank Telescope at 350 MHz. We detected 18 millisecond pulsars (MSPs) in blind searches of the data; 10 of these were discoveries ...

Can Slow Pulsars in Milky Way Globular Clusters Form via Partial Recycling?
The Astrophysical Journal LettersAlongside the population of several hundred radio millisecond pulsars currently known in Milky Way globular clusters, a subset of six slowly spinning pulsars (spin periods 0.3–4 s) are also observed.

Binary periods of cluster pulsars
The Astrophysical Journal, 1990 Tidal capture products dominate the population of active binaries in globular clusters. Recycled radio pulsars will provide the first extensive sample of the period distribution of such binaries. The expected orbital period distribution is computed for the standard evolutionary scenarios involving mass transfer in binaries with captured stars near the ...

Recovering Pulsar Periodicity from Time-of-arrival Data by Finding the Shortest Vector in a Lattice
The Astrophysical JournalThe strict periodicity of pulsars is one of the primary ways through which their nature and environment can be studied, and it has also enabled precision tests of general relativity and studies of nanohertz gravitational waves using pulsar timing arrays (

Identifying Companions in Pulsar Binary Systems via Gaia Data
UniverseIn the optical band, very few pulsars can be directly detected, but some of the pulsar binary companions can be observed. This study leverages high-precision astrometric data from Gaia Data Release 3 (DR3) to identify pulsar companions in binary systems.

A Census of Pulsars in Possible Association with Galactic Open Clusters
The Astrophysical Journal LettersAmong the ∼4000 known pulsars in our Galaxy, ≲10% are found in globular clusters, but none has been confirmed in any open clusters yet, although they outnumber globular clusters by about 20 times.

Testing Gravity with Binary Pulsars in the SKA Era
The Open Journal of AstrophysicsBinary (and trinary) radio pulsars are natural laboratories in space for understanding gravity in the strong field regime, with many unique and precise tests carried out so far, including the most precise tests of the strong equivalence principle and of ...
