4FGL J1318.2+6754: A Long Orbital-period Redback Candidate

The Astrophysical Journal Letters
By combining the Fermi catalog and the single-lined spectroscopic binaries of Gaia Data Release 3 (DR3), we report a new candidate redback millisecond pulsar binary, which is recommended as a target for radio telescopes to detect pulsed signals.

A NICER View of the Nearest and Brightest Millisecond Pulsar: PSR J0437–4715

The Astrophysical Journal Letters
We report Bayesian inference of the mass, radius, and hot X-ray emitting region properties—using data from the Neutron Star Interior Composition ExploreR (NICER)—for the brightest rotation-powered millisecond X-ray pulsar, PSR J0437−4715. Our modeling is

Reprocessing of the Parkes 70 cm Survey and Discovery of a New Radio Pulsar in the Large Magellanic Cloud

The Astrophysical Journal
We have reprocessed the data archived from the Parkes 70 cm (PKS70) pulsar survey with an expanded dispersion measure (DM) search range and an acceleration search.

The role of distant pulsars in the detectability of continuous gravitational waves

Astronomy & Astrophysics
Context. One of the imminent science goals of pulsar timing arrays (PTAs) is the detection of a continuous gravitational wave (CGW) emitted by an individual supermassive black hole binary (SMBHB).

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 ...

The Intrabinary Shock and Companion Star of Redback Pulsar J2215+5135

The Astrophysical Journal
PSR J2215+5135 (J2215) is a “redback” spider pulsar, where the intrabinary shock (IBS) wraps around the pulsar rather than the stellar-mass companion. Spider orbital light curves are modulated, dominated by their binary companion thermal emission in the ...

COBIPULSE: A Systematic Search for Compact Binary Millisecond Pulsars

The Astrophysical Journal
We report here the results obtained from a systematic optical photometric survey aimed at finding new compact binary millisecond pulsars (also known as “spiders”): the COmpact BInary PULsar SEarch. We acquired multiband optical images over 1 yr around 33
