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.

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.

Could acceleration of a pulsar affect braking index?

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
In the coming era of multi-messenger astrophysics, pulsars might be one of the most possible electromagnetic counterparts of the gravitational wave. The braking indices, which are related closely to the electromagnetic radiation of pulsars, are shown to ...

Recent H-alpha Results on Pulsar B2224+65’s Bow-Shock Nebula, the “Guitar” [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2016
We used the 4 m Discovery Channel Telescope (DCT) at Lowell observatory in 2014 to observe the Guitar Nebula, an Hα bow-shock nebula around the high-velocity radio pulsar B2224+65.

Recycled Pulsars [PDF]

open access: yes, 2005
We present the results of a large-area survey for millisecond pulsars (MSPs) at moderately high galactic latitudes with the 64 m Parkes radio telescope, along with follow-up timing and optical studies of the newly-discovered pulsars and several others ...

Understanding the diffuse gamma ray emission of the milky way - from supernova remnants to dark matter [PDF]

open access: yesZbornik Matice Srpske za Prirodne Nauke, 2019
Diffuse gamma ray emission from the Galactic center at 2-3 GeV, as well as the 12 TeV gamma ray excess in the Galactic disk, remain open for debate and represent the missing puzzles in the complete picture of the high-energy Milky Way sky.

Relativistic Effects of Rotation in γ-ray Pulsars—Invited Review

open access: yesGalaxies, 2021
In this paper, we consider the relativistic effects of rotation in the magnetospheres of γ-ray pulsars. The paper reviews the progress achieved in this field during the last three decades.

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 resonantly accelerating electrons [PDF]

open access: yes, 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 (

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
