Binary and Millisecond Pulsars

Living 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 Green Bank North Celestial Cap Survey. IX. Timing Follow-up for 128 Pulsars

The Astrophysical Journal
The Green Bank North Celestial Cap survey is one of the largest and most sensitive searches for pulsars and transient radio objects. Observations for the survey have finished; priorities have shifted toward long-term monitoring of its discoveries.

A Comparison of Millisecond Pulsar Populations between Globular Clusters and the Galactic Field

The Astrophysical Journal, 2023
We have performed a systematic study of the rotational, orbital, and X-ray properties of millisecond pulsars (MSPs) in globular clusters (GCs) and compared their nature with those of the MSPs in the Galactic field (GF).

A coherent acceleration search of the Parkes multi-beam pulsar survey - techniques and the discovery and timing of 16 pulsars [PDF]

, 2013
A fully coherent acceleration search algorithm has been applied to the Parkes multi- beam pulsar survey of the Galactic plane to search for previously undiscovered relativistic binary pulsars. The search has resulted in the discovery of 16 pulsars including a binary millisecond pulsar and an intermittent pulsar. Despite a number of promising candidates

The characteristics of millisecond pulsar emission: I. Spectra, pulse shapes and the beaming fraction

, 1998
We have monitored a large sample of millisecond pulsars using the 100-m Effelsberg radio telescope in order to compare their radio emission properties to the slowly rotating population.

XMM-Newton observations of the small magellanic cloud: Be/X-ray binary pulsars active between October 2006 and June 2007 [PDF]

, 2008
Aims. We analysed eight XMM-Newton observations toward the Small Magellanic Cloud (SMC), performed between October 2006 and June 2007, to investigate high mass X-ray binary systems. Methods.

Search for Short‐Duration Transient Gravitational Waves Emitted by Neutron Star Glitches

Annalen der Physik, Volume 536, Issue 2, February 2024.
The observation rate of pulsar glitches is limited by their electromagnetic observations. There could be a population of the isolated neutron stars in the galaxy for which there is no electromagnetic observations, but they can produce gravitational waves. The all‐sky search for gravitational waves provides better localization of the source sky position

Follow-up Timing of 12 Pulsars Discovered in Commensal Radio Astronomy FAST Survey

The Astrophysical Journal
We present phase-connected timing ephemerides, polarization pulse profiles, and Faraday rotation measurements of 12 pulsars discovered by the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in the Commensal Radio Astronomy FAST Survey.

Cosmology with Gravitational Waves: A Review

Annalen der Physik, Volume 536, Issue 2, February 2024.
The review gives an overview of the most recent advances in gravitational‐wave (GWs) cosmology. After an in‐depth discussion of methodologies and tools for GW cosmology, it presents the latest results on measurements of standard cosmological parameters from the LIGO, Virgo, and KAGRA detections.
