We study the field millisecond pulsar (MSP) population to infer its intrinsic distribution in spin period and luminosity and to determine its spatial distribution within the Galaxy. Our likelihood analysis on data from extant surveys (22 pulsars with periods less than 20 ms) accounts for the following important selection effects: (1) the survey sensitivity as a function of direction, spin period, and sky coverage; (2) interstellar scintillation, which modulates the pulsed flux and causes a net… 

Neutron Star Population Dynamics. II. Three-dimensional Space Velocities of Young Pulsars

We use astrometric, distance, and spindown data on pulsars to (1) estimate three-dimensional velocity components, birth distances from the Galactic plane, and ages of individual objects; (2)

Detecting pulsars in the Galactic Centre

Although high-sensitivity surveys have revealed a number of highly dispersed pulsars in the inner Galaxy, none have so far been found in the Galactic centre (GC) region, which we define to be within

The pulsar contribution to the gamma-ray background

We estimate the contribution of Galactic pulsars, both ordinary and millisecond pulsars (MSPs), to the high-energy ( > 100 MeV) γ−ray background. We pay particular attention to the high-latitude part

A new method for estimates of binary pulsar coalescence rates

Estimates of the Galactic coalescence rate (R) of close binaries with two neutron stars (NS–NS) are known to be uncertain by large factors (about two orders of magnitude) mainly due to the small

Bayesian model comparison and analysis of the Galactic disc population of gamma-ray millisecond pulsars

Pulsed emission from almost one hundred millisecond pulsars (MSPs) has been detected in γ-rays by the Fermi Large-Area Telescope. The global properties of this population remain relatively

A new method for estimating binary pulsar coalescence rates

Estimates of the Galactic coalescence rate (R) of close binaries with two neutron stars (NS-NS) are known to be uncertain by large factors (about two orders of magnitude) mainly due to the small

DYNAMICAL FORMATION OF MILLISECOND PULSARS IN GLOBULAR CLUSTERS

The cumulative luminosity distribution functions (CLFs) of radio millisecond pulsars (MSPs) in globular clusters (GCs) and in the Galactic field at a frequency of 1.4 GHz have been examined. Assuming

The Galactic halo pulsar population

Most population studies of pulsars have hitherto focused on the disc of the Galaxy, the Galactic centre, globular clusters, and nearby galaxies. It is expected that pulsars, by virtue of their natal

Population statistics study of radio and gamma-ray pulsars in the Galactic plane

Abstract We present results of our pulsar population synthesis of normal and millisecond pulsars in the Galactic plane. Over the past several years, a program has been developed to simulate pulsar

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

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

The magnetic fields, ages, and original spin periods of millisecond pulsars

Accurate determination of the spin-down rates of millisecond pulsars requires consideration of the apparent acceleration of the pulsars due to their high transverse velocities. We show that for

A Very Luminous Binary Millisecond Pulsar

We report the discovery of a field binary millisecond pulsar, J0218+4232, with a period of 2.3 ms and in a 2.0 day binary orbit with a ≳0.16 M☉ companion. The new pulsar was serendipitously

WITH very few exceptions1, high Galactic latitudes have not been surveyed with sufficient sensitivity to detect millisecond pulsars. Accordingly we have conducted a preliminary sensitive survey at

STATISTICS OF PULSARS IN GLOBULAR CLUSTERS

More than eighty globular clusters have now been surveyed for pulsars; nearly thirty cluster pulsars have so far been discovered. We review the current status of cluster pulsar searches and their

A new class of radio pulsars

Sufficiently low magnetic field neutron stars which accrete for long times from a surrounding keplerian disk can be spun up to millisecond periods. After accretion ceases, such stars could become

High birth velocities of radio pulsars

NEUTRON stars are usually born during the supernova explosion of a massive star. Any small asymmetry during the explosion can result in a substantial ‘kick’ velocity1 to the neutron star. Pulsars

Pulsar statistics: the birthrate and initial spin periods of radio pulsars

We investigate the birthrate and initial spin periods of radio pulsars using the recently revised pulsar distance scale of Cordes et al. Our technique is based upon the model-free approach originally
