Pulsar Timing Arrays and their Applications

open access: yes, 2011
Millisecond pulsars are intrinsically very stable clocks and precise measurement of their observed pulse periods can be used to study a wide variety of astrophysical phenomena.

Beyond Accretion Limits: The Rise of Pulsating Gems

open access: yesAstronomische Nachrichten, Volume 346, Issue 1, January 2025.
ABSTRACT The discovery of several ultraluminous X‐ray sources exhibiting fast and rapidly evolving X‐ray pulsations unequivocally associates these sources with accreting neutron stars orbiting relatively massive companion stars (> 8M ⊙$$ {}_{\odot } $$).

Decade-long Timing Study of the Black Widow Millisecond Pulsar J1544+4937

open access: yesThe Astrophysical Journal, 2023
Results from 11 yr of radio timing for the eclipsing black widow millisecond pulsar (MSP) binary J1544+4937 is presented in this paper. We report a phase-connected timing model for this MSP, using observations with the Giant Metrewave Radio Telescope ...

Modulated Gamma-ray emission from compact millisecond pulsar binary systems

open access: yes, 2013
A significant amount of the millisecond pulsars has been discovered within binary systems. In several such binary systems the masses of the companion stars have been derived allowing to distinguish two classes of objects, called the Black Widow and the ...

The Origin of Millisecond Pulsars [PDF]

open access: yesInternational Astronomical Union Colloquium, 1996
AbstractAccording to the standard model, millisecond pulsars are the descendants of low-mass X-ray binaries (LMXB). The importance of this formation route has, however, been questioned by several authors on different grounds. This paper critically reviews the arguments and assumptions underlying the standard model.

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 ...

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.

PSR J1453+1902 and the radio luminosities of solitary versus binary millisecond pulsars [PDF]

open access: yes, 2007
We present 3 yr of timing observations for PSR J1453+1902, a 5.79-ms pulsar discovered during a 430-MHz drift-scan survey with the Arecibo telescope. Our observations show that PSR J1453+1902 is solitary and has a proper motion of 8(2) mas/yr.

THE NANOGRAV NINE-YEAR DATA SET: EXCESS NOISE IN MILLISECOND PULSAR ARRIVAL TIMES [PDF]

open access: yes, 2016
Gravitational wave (GW) astronomy using a pulsar timing array requires high-quality millisecond pulsars (MSPs), correctable interstellar propagation delays, and high-precision measurements of pulse times of arrival.

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
