Binary Pulsar Shock Emissions as Galactic Gamma-Ray Sources [PDF]
arXiv, 1995 We address several issues regarding the interpretation of galactic \ggg-ray sources. We consider powerful pulsars in binaries producing X-ray and gamma-ray {\it unpulsed} emission from the shock interaction of relativistic pulsar winds with circumbinary material.

Change of Rotation Measure during the Eclipse of a Black Widow PSR J2051−0827
The Astrophysical Journal, 2023 Black widows are millisecond pulsars ablating their companions. The material blown from the companion blocks the radio emission, resulting in radio eclipses. The properties of the eclipse medium are poorly understood.

X-ray Pulsars in the Small Magellanic Cloud
, 2004 XMM-Newton archival data for the Small Magellanic Cloud have been examined for the presence of previously undetected X-ray pulsars. One such pulsar, with a period of 202 s, is detected.

A characteristic observable signature of preferred-frame effects in relativistic binary pulsars [PDF]
, 2007 In this paper, we develop a consistent, phenomenological methodology to measure preferred-frame effects (PFEs) in binary pulsars that exhibit a high rate of periastron advance.

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 ...

Optical and X-ray variability of two Small Magellanic Cloud X-ray binary pulsars – SXP46.6 and SXP6.85 [PDF]
, 2007 We present long-term optical and RXTE data of two X-ray binary pulsars in the Small Magellanic Cloud, SXP46.6 and SXP6.85. The optical light curves of both sources show substantial (?0.5-0.8 mag) changes over the time-span of the observations.

Navigating the Sotatercept landscape: A meta‐analysis of clinical outcomes
Clinical Cardiology, Volume 47, Issue 1, January 2024.In this study, we performed a meta‐analysis on two randomized clinical trials to assess the impact of Sotatercept on PAH patients. The included papulation were 429 patients with PAH, of which 237 received Sotatercept and 192 received placebo. They were followed for 6 months.

Exploring Unusual High-frequency Eclipses in MSP J1908+2105
The Astrophysical JournalThis paper presents a comprehensive study of the eclipse properties of the spider millisecond pulsar (MSP) J1908+2105, using wide-band observations from the uGMRT and Parkes UWL. For the first time, we observed that this pulsar exhibits extended eclipses
