Populating the Galaxy with pulsars I: stellar & binary evolution

, 2008
The computation of theoretical pulsar populations has been a major component of pulsar studies since the 1970s. However, the majority of pulsar population synthesis has only regarded isolated pulsar evolution.

Microarcsecond VLBI Pulsar Astrometry with PSRπ II. Parallax Distances for 57 Pulsars [PDF]

Astrophysical Journal, 2018
We present the results of PSRπ, a large astrometric project targeting radio pulsars using the Very Long Baseline Array (VLBA). From our astrometric database of 60 pulsars, we have obtained parallax-based distance measurements for all but 3, with a ...

Hydrodynamic Interaction between the Be Star and the Pulsar in the TeV Binary PSR B1259-63/LS 2883

, 2011
We study the interaction between the Be star and the pulsar in the TeV binary PSR B1259-63/LS 2883, using 3-D SPH simulations of the tidal and wind interactions in this Be-pulsar system.

GMRT Discovery of A Millisecond Pulsar in a Very Eccentric Binary System [PDF]

, 2004
We report the discovery of the binary millisecond pulsar J0514-4002A, which is the first known pulsar in the globular cluster NGC 1851 and the first pulsar discovered using the Giant Metrewave Radio Telescope (GMRT). The pulsar has a rotational period of

A pulsar-based time-scale from the International Pulsar Timing Array [PDF]

Monthly notices of the Royal Astronomical Society, 2019
We have constructed a new time-scale, TT(IPTA16), based on observations of radio pulsars presented in the first data release from the International Pulsar Timing Array (IPTA).

The distance to the Vela pulsar gauged with HST parallax oservations [PDF]

, 2001
The distance to the Vela pulsar (PSR B0833-45) has been traditionally assumed to be 500 pc. Although affected by a significant uncertainty, this value stuck to both the pulsar and the SNR. In an effort to obtain a model free distance measurement, we have

POLAR GAP IN THE PULSAR FORCE-FREE MAGNETOSPHERE STRUCTURE

Radio Physics and Radio Astronomy, 2015
The stationary axisymmetric force-free magnetosphere of a pulsar is considered by accounting for the polar gap and current circuit. Adjustment of the vacuum polar gap and the closing current sheet with the force-free magnetosphere of a monopolar ...

Furnishing the Galaxy with Pulsars

, 2007
The majority of pulsar population synthesis studies performed to date have focused on isolated pulsar evolution. Those that have incorporated pulsar evolution within binary systems have tended to either treat binary evolution poorly of evolve the pulsar ...

Searching for gravitational waves from the Crab pulsar - the problem of timing noise [PDF]

, 2003
Of the current known pulsars, the Crab pulsar (B0531+21) is one of the most promising sources of gravitational waves. The relatively large timing noise of the Crab causes its phase evolution to depart from a simple spin-down model.
