Low-Frequency Spectral Energy Distributions of Radio Pulsars Detected with the Murchison Widefield Array [PDF]
Publications Astronomical Society of Australia, 2017 We present low-frequency spectral energy distributions of 60 known radio pulsars observed with the Murchison Widefield Array telescope. We searched the GaLactic and Extragalactic All-sky Murchison Widefield Array survey images for 200-MHz continuum radio

Radio emission of the Crab and Crab-like pulsars [PDF]
Monthly notices of the Royal Astronomical Society, 2018 The pulsar radio emission is commonly associated with the plasma outflow in the open field line tube; then a pencil beam is emitted along the pulsar magnetic axis.

LUMINOSITIES OF RADIO PULSARS [PDF]
International Journal of Modern Physics D, 2013 Luminosity is an intrinsic property of radio pulsars related to the properties of the magnetospheric plasma and the beam geometry, and inversely proportional to the observing frequency. In traditional models, luminosity has been considered as a function of the spin parameters of pulsars.

Radio Pulsars in the Magellanic Clouds [PDF]
The Astrophysical Journal, 2001 We report the results of a survey of the Small Magellanic Cloud (SMC) for radio pulsars conducted with the 20-cm multibeam receiver of the Parkes 64-meter telescope. This survey targeted a more complete region of the SMC than a previous pulsar search and had an improvement in sensitivity by a factor of about two for most pulsar periods.

Bunching Coherent Curvature Radiation in Three-dimensional Magnetic Field Geometry: Application to Pulsars and Fast Radio Bursts [PDF]
Astrophysical Journal, 2017 The extremely high brightness temperatures of pulsars and fast radio bursts (FRBs) require their radiation mechanisms to be coherent. Coherent curvature radiation from bunches has been long discussed as the mechanism for radio pulsars and recently for ...

Estimating the Evolution of Sparks in the Partially Screened Gap of Pulsars from Subpulse Drifting
The Astrophysical Journal, 2023 A novel scheme has been developed to show that the observed phase behavior associated with subpulse drifting from two pulsars, J1034−3224 and J1720−2933, can be used to obtain the magnetic field configuration in the partially screened gap (PSG).

Mode Changing in PSR B0844-35 and PSR B1758-29 with Enhanced Emission at the Profile Centers
The Astrophysical Journal, 2023 We have studied the single pulse emission from two pulsars, PSR B0844-35 and PSR B1758-29, over a wide frequency range of 300–750 MHz using the upgraded Giant Metrewave Radio Telescope.

Giant pulses of pulsar radio emission [PDF]
Astrophys.SpaceSci.308:563-567,2007, 2007 Review report of giant pulses of pulsar radio emission, based on our detections of four new pulsars with giant pulses, and the comparative analysis of the previously known pulsars with giant pulses, including the Crab pulsar and millisecond pulsar PSR B1937+21.
