Born to be recycled: A comprehensive population synthesis of the Galactic millisecond pulsars

open access: yesAstronomy & Astrophysics
Context. Millisecond pulsars (MSPs) are the oldest and fastest pulsars known to date. The first MSP to be discovered was PSR B1937+21 in 1982. To explain how these pulsars could be formed, a new hypothesis was formulated: the recycling of pulsars, i.e ...

A time-variable, phase-dependent emission line in the X-ray spectrum of the isolated neutron star RXJ0822–4300 [PDF]

open access: yes, 2012
RX J0822−4300 is the central compact object associated with the Puppis A supernova remnant. Previous X-ray observations suggested RX J0822−4300 to be a young neutron star with a weak dipole field and a peculiar surface temperature distribution dominated ...

The search for statistical anisotropy in the gravitational-wave background with pulsar timing arrays

open access: yesThe Open Journal of Astrophysics, 2019
Pulsar-timing arrays (PTAs) are seeking gravitational waves from supermassive-black-hole binaries, and there are prospects to complement these searches with stellar-astrometry measurements.

Optical and Infrared Lightcurve Modeling of the Gamma-ray Millisecond Pulsar 2FGL J2339.6-0532 [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2013
We report the detection of a quasi-sinusoidally modulated optical flux with a period of 4.6343 hour in the optical and infrared band of the Fermi source 2FGL J2339.7-0531.

A Preliminary Study of Large Scale Pulsar Candidate Sifting Based on Parallel Hybrid Clustering

open access: yesUniverse, 2022
Pulsar candidate sifting is an essential part of pulsar analysis pipelines for discovering new pulsars. To solve the problem of data mining of a large number of pulsar data using a Five-hundred-meter Aperture Spherical radio Telescope (FAST), a parallel ...

Pulsar Electrodynamics — Pulsars and Puzzlers — [PDF]

open access: yesInternational Astronomical Union Colloquium, 1996
Abstract A gedanken experiment presented here provides basic understanding of how the pulsar magnetosphere operates. We discuss current issues about the electric-field acceleration along magnetic field lines and subsequent pair creation, and also about the pulsar wind problem.

Particle acceleration in Pulsars and Pulsar Wind Nebulae

open access: yesFoundations of Cosmic Ray Astrophysics, 2022
These notes summarise the contents of the lectures I delivered at the International School of Physics "Enrico Fermi" on "Foundations of Cosmic Ray Astrophysics". The lectures were dealing with the physics of Pulsars and Pulsar Wind Nebulae (PWNe) in the Cosmic Ray (CR) perspective.

Pulsed γ-ray emission from magnetar 1E 2259+586 [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2013
Anomalous X-ray pulsars (AXPs) are thought to be magnetars which are young isolated neutron stars with extremely strong magnetic fields of >1014 Gauss.

On the aberration–retardation effects in pulsars

open access: yes, 2009
The magnetospheric locations of pulsar radio emission region are not well known. The actual form of the so-called radius-to-frequency mapping should be reflected in the aberration-retardation (A/R) effects that shift and/or delay the photons depending on
