Detection of 16 Gamma-Ray Pulsars Through Blind Frequency Searches Using the Fermi LAT

open access: yesScience, 2009
Pulsars are rapidly-rotating, highly-magnetized neutron stars emitting radiation across the electromagnetic spectrum. Although there are more than 1800 known radio pulsars, until recently, only seven were observed to pulse in gamma rays and these were ...

The origin of single radio pulsars [PDF]

open access: yes, 1999
By comparing relative rates of supernovae versus formation rates of single radio pulsars, recycled pulsars, binary pulsars and X-ray binaries we put strong limits on the progenitors of radio pulsars and on the requirement of an asymmetry in the supernova.

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.

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.

Classification of unassociated fermi-LAT sources [PDF]

open access: yesITM Web of Conferences, 2022
The Large Area Telescope (LAT) on board NASA’s Fermi Gamma-ray Space telescope has detected 5788 sources in the 4FGL catalogue. Among them, 271 have been associated to pulsars, 3436 to blazars, and 1782 remain unassociated sources.

Multi-Messenger Astrophysics of a Millisecond Pulsar Orbiting around a Massive Black Hole

open access: yesUniverse, 2022
Extreme-mass-ratio and intermediate-mass-ratio binaries with a millisecond pulsar are gravitational-wave sources that emit also electromagnetic radiation.

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 ...

Observations of the gamma-ray pulsar J1836+5925 at 111 MHz

open access: yesOpen Astronomy, 2021
We describe the 10-day radio observations of the gamma-ray pulsar J1836+5925. Observations were carried out in the Pushchino Radio Astronomical Observatory at the frequency of 111 MHz using the Large Phased Array of the Lebedev Physical Institute.

Young Radio Pulsars in Galactic Globular Clusters [PDF]

open access: yes, 2011
Currently three isolated radio pulsars and one binary radio pulsar with no evidence of any previous recycling are known in 97 surveyed Galactic globular clusters.

Gravity Tests with Radio Pulsars

open access: yesUniverse, 2020
The discovery of the first binary pulsar in 1974 has opened up a completely new field of experimental gravity. In numerous important ways, pulsars have taken precision gravity tests quantitatively and qualitatively beyond the weak-field slow-motion ...
