On the detectability of eccentric binary pulsars [PDF]
Monthly Notices of the Royal Astronomical Society, 2013 By generalizing earlier work of Johnston & Kulkarni, we present a detailed description of the reduction in the signal-to-noise ratio for observations of binary pulsars. We present analytical expressions, and provide software, to calculate the sensitivity

Vainshtein Mechanism in Binary Pulsars [PDF]
Physical Review D, 2012 We compute the scalar gravitational radiation from a binary pulsar system in the simplest model that exhibits the Vainshtein mechanism. The mechanism is successful in screening the effect from scalar fields conformally coupled to matter, although ...

Binary pulsars as dark-matter probes [PDF]
Physical Review D, 2015 During the motion of a binary pulsar around the Galactic center, the pulsar and its companion experience a wind of dark-matter particles that can affect the orbital motion through dynamical friction.

Long-term observations of the pulsars in 47 Tucanae. I. A study of four elusive binary systems [PDF]
, 2016 For the past couple of decades, the Parkes radio telescope has been regularly observing the millisecond pulsars in 47 Tucanae (47 Tuc). This long-term timing program was designed to address a wide range of scientific issues related to these pulsars and ...

Discovery of Five Binary Radio Pulsars [PDF]
The Astrophysical Journal, 2000 We report on five binary pulsars discovered in the Parkes multibeam Galactic plane survey. All of the pulsars are old, with characteristic ages 1-11 Gyr, and have relatively small inferred magnetic fields, 5-90e8 G.

Periodicity search for Pulsar Binaries with TESS [PDF]
ApJL 895 L36 (2020), 2020 Pulsar binaries, in particular redback systems, provide good sources to study the pulsar wind flow and its interaction with the companion stars. {\it Fermi}-LAT have proposed probable pulsar binary candidates in its catalogs. To identify pulsar binary sources from the catalog, orbital modulation search of binary candidates is an effective way.

Algorithmic Pulsar Timer for Binaries
The Astrophysical JournalPulsar timing is a powerful tool that, by accounting for every rotation of a pulsar, precisely measures the spin frequency, spin frequency derivatives, astrometric position, binary parameters when applicable, properties of the interstellar medium, and ...

Relativistic Gravity and Binary Radio Pulsars [PDF]
1999, AIP Conf. Proc, Eds. C. P. Burgess, R. C. Myers, 493, pp
3-14, 1999 Following a summary of the basic principles of pulsar timing, we present a review of recent results from timing observations of relativistic binary pulsars. In particular, we summarize the status of timing observations of the much celebrated original binary pulsar PSR B1913+16, draw attention to the recent confirmation of strong evidence for geodetic ...

Eclipsing Binary Pulsars [PDF]
arXiv, 2004 The first eclipsing binary pulsar, PSR B1957+20, was discovered in 1987. Since then, 13 other eclipsing low-mass binary pulsars have been found, 12 of these are in globular clusters. In this paper we list the known eclipsing binary pulsars and their properties, with special attention to the eclipsing systems in 47 Tuc.

The Third Fermi Large Area Telescope Catalog of Gamma-Ray Pulsars
The Astrophysical Journal, 2023 We present 294 pulsars found in GeV data from the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope. Another 33 millisecond pulsars (MSPs) discovered in deep radio searches of LAT sources will likely reveal pulsations once phase-connected
