A Search for Pulsars around Sgr A* in the First Event Horizon Telescope Data Set

open access: yesThe Astrophysical Journal, 2023
In 2017 the Event Horizon Telescope (EHT) observed the supermassive black hole at the center of the Milky Way, Sagittarius A* (Sgr A*), at a frequency of 228.1 GHz ( λ = 1.3 mm).

Pulsar Electrodynamics — Pulsars and Puzzlers — [PDF]

open access: yesInternational Astronomical Union Colloquium, 1996
Abstract A gedanken experiment presented here provides basic understanding of how the pulsar magnetosphere operates. We discuss current issues about the electric-field acceleration along magnetic field lines and subsequent pair creation, and also about the pulsar wind problem.

REPEATING FAST RADIO BURSTS FROM HIGHLY MAGNETIZED PULSARS TRAVELING THROUGH ASTEROID BELTS [PDF]

open access: yes, 2016
Very recently, Spitler et al. and Scholz et al. reported their detections of 16 additional bright bursts in the direction of the fast radio burst (FRB) 121102.

Polarimetric Evidence of the First White Dwarf Pulsar: The Binary System AR Scorpii

open access: yesGalaxies, 2018
The binary star AR Scorpii was recently discovered to exhibit high amplitude coherent variability across the electromagnetic spectrum (ultraviolet to radio) at two closely spaced ∼2 min periods, attributed to the spin period of a white dwarf and the beat

Discovery of Four Pulsars in a Pilot Survey at Intermediate Galactic Latitudes with FAST

open access: yesThe Astrophysical Journal, 2023
We present the discovery and timing results of four pulsars discovered in a pilot survey at intermediate Galactic latitudes with the Five-hundred Aperture Spherical Telescope (FAST). Among these pulsars, two belong to the category of millisecond pulsars (

Fast radio bursts as giant pulses from young rapidly rotating pulsars [PDF]

open access: yes, 2016
We discuss possible association of fast radio bursts (FRBs) with supergiant pulses emitted by young pulsars (ages $\sim$ tens to hundreds of years) born with regular magnetic field but very short -- few milliseconds -- spin periods.

Born to be recycled: A comprehensive population synthesis of the Galactic millisecond pulsars

open access: yesAstronomy & Astrophysics
Context. Millisecond pulsars (MSPs) are the oldest and fastest pulsars known to date. The first MSP to be discovered was PSR B1937+21 in 1982. To explain how these pulsars could be formed, a new hypothesis was formulated: the recycling of pulsars, i.e ...

New long-term braking index measurements for glitching pulsars using a glitch-template method [PDF]

open access: yes, 2016
Braking index measurements offer the opportunity to explore the processes affecting the long-term spin evolution of pulsars and possible evolutionary connections between the various pulsar populations. For young pulsars the long-term trends are generally

Two Candidate Pulsar TeV Halos Identified from Property-similarity Studies

open access: yesThe Astrophysical Journal, 2023
Teraelectronvolt halos have been suggested to be a common phenomenon associated with middle-aged pulsars. Based on our recent work on the middle-aged pulsar J0631+1036, which is the only known source positionally coincident with a hard teraelectronvolt γ
