Discovery of an Isolated Compact Object at High Galactic Latitude
, 2007 We report discovery of a compact object at high Galactic latitude. The object was initially identified as a ROSAT All-Sky Survey Bright Source Catalog X-ray source, 1RXS J141256.0+792204, statistically likely to possess a high X-ray to optical flux ratio.

On an Autonomous Pulsar Observation–Based Timekeeping Method for Deep Space
International Journal of Aerospace Engineering, Volume 2025, Issue 1, 2025.To provide autonomous and accurate time service for deep space missions, a pulsar observation–based timekeeping method is documented in this paper, which utilizes pulsars as the time information source. Firstly, the pulsar observation noise is remodeled as the combination of the Gaussian noise and colored noise, and the detailed expression of the ...

Discovery of an X-ray Nebula associated with PSR J2124-3358 [PDF]
, 2006 We report the discovery of an X-ray nebula associated with the nearby millisecond pulsar PSR J2124-3358. This is the first time that extended emission from a solitary millisecond pulsar is detected.

Discovery of Two Relativistic Neutron Star-White Dwarf Binaries [PDF]
, 2000 We have discovered two recycled pulsars in relativistic orbits as part of the first high-frequency survey of intermediate Galactic latitudes. PSR J1157-5112 is a 44 ms pulsar and the first recycled pulsar with an ultra-massive (M > 1.14 Mo) white dwarf ...

Search for Short‐Duration Transient Gravitational Waves Emitted by Neutron Star Glitches
Annalen der Physik, Volume 536, Issue 2, February 2024.The observation rate of pulsar glitches is limited by their electromagnetic observations. There could be a population of the isolated neutron stars in the galaxy for which there is no electromagnetic observations, but they can produce gravitational waves. The all‐sky search for gravitational waves provides better localization of the source sky position

Identifying Companions in Pulsar Binary Systems via Gaia Data
UniverseIn the optical band, very few pulsars can be directly detected, but some of the pulsar binary companions can be observed. This study leverages high-precision astrometric data from Gaia Data Release 3 (DR3) to identify pulsar companions in binary systems.

Physics of radio emission in gamma-ray pulsars [PDF]
, 2016 Propagation of radio emission in pulsar magnetosphere is reviewed. The effects of polarization transfer, induced scattering and reprocessing to high energies are analysed with an especial emphasis on the implications for the gamma-ray pulsars.

Heavy Elements and Electromagnetic Transients from Neutron Star Mergers
Annalen der Physik, Volume 536, Issue 2, February 2024.Astro‐(physics) has made major leaps forward through the combined information provided by both gravitational waves and electromagnetic emission from the first detected neutron star merger event. This review provides an up‐to‐date overview of today's understanding of neutron star mergers and their electromagnetic emission and it discusses possible ...
