Pulsar Wind Nebulae Created by Fast-Moving Pulsars

, 2017
We review multiwavelength properties of pulsar wind nebulae (PWNe) created by supersonically moving pulsars and the effects of pulsar motion on the PWN morphologies and the ambient medium.

A new nearby pulsar wind nebula overlapping the RX J0852.0-4622 supernova remnant [PDF]

, 2012
Energetic pulsars can be embedded in a nebula of relativistic leptons which is powered by the dissipation of the rotational energy of the pulsar.

The specifics of pulsar radio emission

Open Astronomy, 2022
A characteristic property of pulsars is pulsed periodic radio emission, which has a high stability of periods. Despite the high stability of the emission periods of pulsars, monitoring the time of arrival of pulses (timing) shows the presence of ...

Comparing Recent Pulsar Timing Array Results on the Nanohertz Stochastic Gravitational-wave Background

Astrophysical Journal
The Australian, Chinese, European, Indian, and North American pulsar timing array (PTA) collaborations recently reported, at varying levels, evidence for the presence of a nanohertz gravitational-wave background (GWB).

Realistic sensitivity curves for pulsar timing arrays [PDF]

Physical Review D, 2019
We construct realistic sensitivity curves for pulsar timing array searches for gravitational waves, incorporating both red and white noise contributions to individual pulsar noise spectra, as well as the effect of fitting to a pulsar timing model.

Glitches in Southern Pulsars [PDF]

International Astronomical Union Colloquium, 2000
AbstractParkes timing observations of 31 mostly young pulsars over nearly nine years are described. A total of 29 glitches were detected, of which 19 are previously unreported. Twelve glitches were seen in PSR J1341–6220, making this the most frequently glitching pulsar known, and the largest known glitch was detected in PSR J1614–5047.

Bow-shock Pulsar Wind Nebulae Passing Through Density Discontinuities

, 2016
Bow-shock pulsar wind nebulae are a subset of pulsar wind nebulae that form when the pulsar has high velocity due to the natal kick during the supernova explosion.

Quark Deconfinement in Rotating Neutron Stars

Universe, 2017
In this paper, we use a three flavor non-local Nambu–Jona-Lasinio (NJL) model, an improved effective model of Quantum Chromodynamics (QCD) at low energies, to investigate the existence of deconfined quarks in the cores of neutron stars.

LOFAR Discovery of a 23.5 s Radio Pulsar [PDF]

Astrophysical Journal, 2018
We present the discovery of PSR J0250+5854, a radio pulsar with a spin period of 23.5 s. This is the slowest-spinning radio pulsar known. PSR J0250+5854 was discovered by the LOFAR Tied-Array All-Sky Survey (LOTAAS), an all-northern-sky survey for ...

Millisecond pulsar velocities [PDF]

Monthly Notices of the Royal Astronomical Society, 1999
We present improved timing parameters for 13 millisecond pulsars (MSPs), including nine new proper motion measurements. These new proper motions bring to 23 the number of MSPs with measured transverse velocities. In light of these new results we present and compare the kinematic properties of MSPs with those of ordinary pulsars.
