The LOFAR pilot surveys for pulsars and fast radio transients [PDF]

open access: yes, 2014
We have conducted two pilot surveys for radio pulsars and fasttransients with the Low-Frequency Array (LOFAR) around 140 MHz and herereport on the first low-frequency fast-radio burst limit and thediscovery of two new pulsars. The first survey, the LOFAR

Wide-bandwidth Observations of PSR J0941–39 and PSR J1107–5907

open access: yesThe Astrophysical Journal, 2023
We present a polarization analysis of PSR J0941–39 and PSR J1107–5907, which exhibit transitions between being pulsars and rotating radio transients (RRATs), using the ultrawide-bandwidth low-frequency receiver on Murriyang, the Parkes 64 m radio ...

Are radio pulsars strange stars ? [PDF]

open access: yesAstronomy & Astrophysics, 2001
A remarkably precise observational relation for pulse core component widths of radio pulsars is used to derive stringent limits on pulsar radii, strongly indicating that pulsars are strange stars rather than neutron stars. This is achieved by inclusion of general relativistic effects due to the pulsar mass on the size of the emission region needed to ...

Magnetic fields of radio pulsars [PDF]

open access: yesAstronomy Reports, 2017
We used the magneto-dipole radiation mechanism for the braking of radio pulsars to calculate the new values of magnetic inductions at the surfaces of neutron stars. For this aim we estimated the angles ? between the rotation axis and the magnetic moment of the neutron star for 376 radio pulsars using three different methods. It was shown that there was

Gravitoastronomy with neutron stars [PDF]

open access: yes, 2004
Recent advances in gravitational wave detectors mean that we can start to make astrophysically important statements about the physics of neutron stars based on observed upper limits to their gravitational luminosity.

Radio pulsars with expected gamma radiation and gamma-ray pulsars as pulsating radio emitters [PDF]

open access: yesResearch in Astronomy and Astrophysics, 2018
Abstract Pulsars play a crucial astrophysical role as highly energetic compact radio, X-ray and gamma-ray sources. Our previous works show that radio pulsars identified as pulsing gamma-ray sources by the Large Area Telescope (LAT) on board the Fermi Gamma-Ray Space Telescope

The specifics of pulsar radio emission

open access: yesOpen 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 ...
