Single Millisecond Pulsars from Dynamical Interaction Processes in Dense Star Clusters [PDF]

open access: goldThe Astrophysical Journal
Globular clusters (GCs) are particularly efficient at forming millisecond pulsars. Among these pulsars, about half lack a companion star, a significantly higher fraction than in the Galactic field.

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.

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 ...

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.

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.

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 ...

Post-main-sequence planetary system evolution [PDF]

open access: yesRoyal Society Open Science, 2016
The fates of planetary systems provide unassailable insights into their formation and represent rich cross-disciplinary dynamical laboratories. Mounting observations of post-main-sequence planetary systems necessitate a complementary level of theoretical
