Tests of gravitational symmetries with pulsar binary J1713+0747 [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Symmetries play a fundamental role in modern theories of gravity. The strong equivalence principle (SEP) constitutes a collection of gravitational symmetries which are all implemented by general relativity.

2S 1553-542: a Be/X-ray binary pulsar on the far side of the Galaxy [PDF]
, 2016 We report the results of a comprehensive analysis of X-ray (Chandra and Swift observatories), optical (Southern African Large Telescope, SALT) and near-infrared (the VVV survey) observations of the Be/X-ray binary pulsar 2S1553-542.

Pulsar emission amplified and resolved by plasma lensing in an eclipsing binary [PDF]
Nature, 2018 Radio pulsars scintillate because their emission travels through the ionized interstellar medium along multiple paths, which interfere with each other.

Trompe L'Oeil 'binary' pulsars
The Astrophysical Journal, 1990 A freely precessing pulsar produces pulse phase residuals which can mimic those of a pulsar in a binary orbit. In particular, discrete sets of phase residuals due to precessional motion of an isolated pulsar are sampled; it is shown that this data is well fit by residuals from a binary pulsar in a sufficiently tight orbit.

Binary system delays and timing noise in searches for gravitational waves from known pulsars [PDF]
, 2007 The majority of fast millisecond pulsars are in binary systems, so that any periodic signal they emit is modulated by both Doppler and relativistic effects.

Relativistic Binary Pulsars with Black Hole Companions [PDF]
The Astrophysical Journal, 2005 Binaries containing a stellar-mass black hole and a recycled radio pulsar have so far eluded detection. We present a focused investigation of the formation and evolution of these systems in the Galactic disk, highlighting the factors that limit their numbers and the reasons why they may be extremely rare.

Physical Review X, 2017 Pulsar timing and laser-interferometer gravitational-wave (GW) detectors are superb laboratories to study gravity theories in the strong-field regime. Here, we combine these tools to test the mono-scalar-tensor theory of Damour and Esposito-Farèse (DEF),

The Effect of Irradiation on the Spin of Millisecond Pulsars
The Astrophysical Journal Letters, 2023 A millisecond pulsar (MSP) is an old neutron star (NS) that has accreted material from its companion star, causing it to spin up, which is known as the recycling scenario.

Probing the properties of the pulsar wind via studying the dispersive effects in the pulses from the pulsar companion in a double neutron-star binary system [PDF]
, 2017 The velocity and density distribution of $e^\pm$ in the pulsar wind are crucial distinction among magnetosphere models, and contains key parameters determining the high energy emission of pulsar binaries.

A Radio Pulsar/X-ray Binary Link [PDF]
Science, 2009 From X-ray Binary to Pulsar Pulsars with millisecond rotational periods are thought to originate from neutron stars in low-mass x-ray binaries that had their spin frequencies increased by long-lasting mass transfer from their companion stars.
