Radio Pulsars Resonantly Accelerating Electrons

open access: yesAstronomy, 2023
Based on the recently demonstrated resonant wave–wave process, it is shown that electrons can be accelerated to ultra-relativistic energies in the magnetospheres of radio pulsars. The energization occurs via the resonant interaction of the electron wave (

Identifying Pulsar Candidates in Interferometric Radio Images Using Scintillation

open access: goldThe Astrophysical Journal
Pulsars have been primarily detected by their narrow pulses or periodicity in time domain data. Interferometric surveys for pulsars are challenging due to the trade-off between beam sensitivity and beam size and the corresponding tradeoff between survey ...

Gamma Ray Pulsars and Opportunities for the MACE Telescope

open access: yesGalaxies, 2023
Rapidly rotating neutron stars with very strong surface magnetic fields are observed to emit pulsed emission in the whole range of electromagnetic spectrum from radio to high-energy gamma rays.

FIRST DETECTION AT THE DECAMETER WAVELENGTHS AND CLARIFICATION OF RADIATION PARAMETERS OF PSR J2325-0530, PSR J0613+3731, AND PSR J1426+52 RADIO PULSARS [PDF]

open access: yesRadio Physics and Radio Astronomy, 2020
Purpose: Due to the significant increase of a number of pulsars discovered with high-frequency radio telescopes over the last ten years and the necessity to obtain accurate parameters of their decameter radiation (as well as to identify single pulses ...

Radio-quiet Gamma-ray Pulsars [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2016
A radio-quiet γ-ray pulsar is a neutron star that has significant γ-ray pulsation but without observed radio emission or only limited emission detected by high sensitivity radio surveys.

On the galactic distributions of radio pulsars and plasma density [PDF]

open access: yesSerbian Astronomical Journal, 2016
A brief review of distance measurement methods for some astronomical sources is presented. Galactic plasma density distribution as related to the distribution of radio pulsars is discussed and a method for constructing relations between ...

The Third Fermi Large Area Telescope Catalog of Gamma-Ray Pulsars

open access: yesThe Astrophysical Journal, 2023
We present 294 pulsars found in GeV data from the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope. Another 33 millisecond pulsars (MSPs) discovered in deep radio searches of LAT sources will likely reveal pulsations once phase-connected

On the Spectral Shape of Non-recycled γ-ray Pulsars [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2016
More than 100 γ−ray pulsars have been discovered by the Fermi Gamma-ray Space Telescope. With a significantly enlarged sample size, it is possible to compare the properties of different classes. Radio-quiet (RQ) γ−ray pulsars form a distinct population,

Galactic populations of radio and gamma-ray pulsars in the polar cap model [PDF]

open access: yes, 2001
We simulate the characteristics of the Galactic population of radio and $\gamma$-ray pulsars using Monte Carlo techniques. At birth, neutron stars are spatially distributed in the Galactic disk, with supernova-kick velocities, and randomly dispersed in ...

Investigation of Emission States of PSR J1722–3207

open access: yesThe Astrophysical Journal, 2023
We have conducted a detailed study of single-pulse emission from PSR J1722−3207, which was observed at 1369 MHz using the Parkes 64 m radio telescope. PSR J1722−3207 has an asymmetric two-component mean pulse profile.
