The Astrophysical JournalWhile the precise mechanism of generating pulsed coherent radio emission from pulsars remains elusive, certain gap-invoking models (especially, the inner gap model) offer a comprehensive and plausible explanation for the genesis and termination of such ...

RADIO-QUIET AND RADIO-LOUD PULSARS: SIMILAR IN GAMMA-RAYS BUT DIFFERENT IN X-RAYS [PDF]
, 2015 We present new Chandra and XMM-Newton observations of a sample of eight radio-quiet (RQ) γ-ray pulsars detected by the Fermi Large Area Telescope. For all eight pulsars we identify the X-ray counterpart, based on the X-ray source localization and the ...

Constraint‐Aware Operating‐Point Selection for FAST Pulsar Candidate Screening
Advances in Astronomy, Volume 2026, Issue 1, 2026.FAST pulsar surveys generate candidate volumes that make manual review a practical bottleneck, so fixed‐threshold classification is often mismatched to deployment under limited review budgets. We formulate candidate screening as a constrained operating‐point selection problem: given model scores, the decision threshold is chosen to maximise recall ...

Unveiling the Emission Properties of Three Long-period Pulsars Using FAST
The Astrophysical Journal Supplement SeriesWe detail the emission behaviors of three long-period pulsars detected using the Five-hundred-meter Aperture Spherical radio Telescope (FAST) during the Commensal Radio Astronomy FAST survey.

Testing Relativistic Gravity with Radio Pulsars [PDF]
, 2014 Before the 1970s, precision tests for gravity theories were constrained to the weak gravitational fields of the Solar system. Hence, only the weak-field slow-motion aspects of relativistic celestial mechanics could be investigated. Testing gravity beyond

Journal of Chemistry, Volume 2026, Issue 1, 2026.The development of efficient and scalable catalysts for polyether amine (PEA) synthesis via reductive amination remains an enduring industrial challenge. In this study, bimetallic NiCu alloys supported on amorphous alumina were rationally designed for the amination of low‐molecular‐weight polyether (PPG‐230).

The MeerKAT Pulsar Timing Array: the first search for gravitational waves with the MeerKAT radio telescope [PDF]
Monthly notices of the Royal Astronomical SocietyPulsar timing arrays search for nanohertz-frequency gravitational waves by regularly observing ensembles of millisecond pulsars over many years to look for correlated timing residuals.
