On the soft emission mechanism in X-ray pulsars

open access: yesJournal of Theoretical and Applied Physics, 2019
We propose a mechanism responsible for the soft emission in X-ray pulsars. We discuss the origin of the soft emission for isolated X-ray pulsars as well as for soft gamma-ray repeaters and anomalous X-ray pulsars.

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 (

Pulsar [PDF]

open access: yesProceedings of the 11th ACM Conference on Emerging Networking Experiments and Technologies, 2015
With the great success of LTE(-A) outdoor, LTE-based small cell technology has become popular and is penetrating indoor enterprise environment, co-existing with WiFi networks, to provide better user experience or Quality-of-Experience (QoE). However, accurate estimation of LTE links is challenging and critical to continue providing QoE for many ...

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

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.

Radio pulsar binaries in globular clusters: their orbital eccentricities and stellar interactions

open access: yes, 2009
High sensitivity searches of globular clusters (GC) for radio pulsars by improved pulsar search algorithms and sustained pulsar timing observations have so far yielded some 140 pulsars in more than two dozen GCs.

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
