On an Autonomous Pulsar Observation–Based Timekeeping Method for Deep Space

open access: yesInternational Journal of Aerospace Engineering, Volume 2025, Issue 1, 2025.
To provide autonomous and accurate time service for deep space missions, a pulsar observation–based timekeeping method is documented in this paper, which utilizes pulsars as the time information source. Firstly, the pulsar observation noise is remodeled as the combination of the Gaussian noise and colored noise, and the detailed expression of the ...

Gamma-ray Burst Afterglow with Continuous Energy Injection: Signature of a Highly-Magnetized Millisecond Pulsar

open access: yes, 2001
We investigate the consequences of a continuously injecting central engine on the gamma-ray burst afterglow emission, focusing more specifically on a highly-magnetized millisecond pulsar engine.

PSR J1024–0719: A MILLISECOND PULSAR IN AN UNUSUAL LONG-PERIOD ORBIT [PDF]

open access: yes, 2016
PSR J1024–0719 is a millisecond pulsar that was long thought to be isolated. However, puzzling results concerning its velocity, distance, and low rotational period derivative have led to a reexamination of its properties.

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

open access: yesAnnalen 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

Identifying Companions in Pulsar Binary Systems via Gaia Data

open access: yesUniverse
In 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.

The NANOGrav 12.5 yr Data Set: Polarimetry and Faraday Rotation Measures from Observations of Millisecond Pulsars with the Green Bank Telescope

open access: yesThe Astrophysical Journal, 2022
In this work, we present polarization profiles for 23 millisecond pulsars observed at 820 and 1500 MHz with the Green Bank Telescope as part of the NANOGrav pulsar timing array.

Twenty Years of Searching for (and Finding) Globular Cluster Pulsars

open access: yes, 2007
Globular clusters produce orders of magnitude more millisecond pulsars per unit mass than the Galactic disk. Since the first cluster pulsar was uncovered twenty years ago, at least 138 have been identified - most of which are binary millisecond pulsars ...

DISCOVERY OF A REDBACK MILLISECOND PULSAR CANDIDATE: 3FGL J0212.1+5320 [PDF]

open access: yes, 2016
We present a multiwavelength study of the unidentified Fermi object, 3FGL J0212.1+5320. Within the 95% error ellipse, Chandra detects a bright X-ray source (i.e., erg cm−2 s−1) that has a low-mass optical counterpart ( and K).

Heavy Elements and Electromagnetic Transients from Neutron Star Mergers

open access: yesAnnalen der Physik, Volume 536, Issue 2, February 2024.
Astro‐(physics) has made major leaps forward through the combined information provided by both gravitational waves and electromagnetic emission from the first detected neutron star merger event. This review provides an up‐to‐date overview of today's understanding of neutron star mergers and their electromagnetic emission and it discusses possible ...
