Search for an Isotropic Gravitational-wave Background with the Parkes Pulsar Timing Array
Astrophysical Journal Letters, 2023 Pulsar timing arrays aim to detect nanohertz-frequency gravitational waves (GWs). A background of GWs modulates pulsar arrival times and manifests as a stochastic process, common to all pulsars, with a signature spatial correlation.

Multi-Messenger Astrophysics of a Millisecond Pulsar Orbiting around a Massive Black Hole
Universe, 2022 Extreme-mass-ratio and intermediate-mass-ratio binaries with a millisecond pulsar are gravitational-wave sources that emit also electromagnetic radiation.

Auroras on Planets around Pulsars
The Astrophysical Journal Letters, 2023 The first extrasolar planets were discovered serendipitously, by finding the slight variation in otherwise highly regular timing of the pulses, caused by the planets orbiting a millisecond pulsar.

Millisecond pulsar velocities [PDF]
Monthly Notices of the Royal Astronomical Society, 1999 We present improved timing parameters for 13 millisecond pulsars (MSPs), including nine new proper motion measurements. These new proper motions bring to 23 the number of MSPs with measured transverse velocities. In light of these new results we present and compare the kinematic properties of MSPs with those of ordinary pulsars.

The Astrophysical Journal Letters, 2023 The most distant globular cluster (GC) with known pulsars is NGC 5024 (M53). In this paper, we report the discovery of a new binary millisecond pulsar, PSR J1312+1810E (M53E), and present the new timing solutions for M53B–E based on 22 observations from ...

A Light Redback Companion of PSR J1622–0315 and Irradiation Power in Spider Systems
The Astrophysical Journal, 2023 We report optical observations of the millisecond pulsar binary system PSR J1622–0315 with the Lulin 1 m telescope in Taiwan and the Lijiang 2.4 m telescope in China between 2019 and 2021.

Transitional Millisecond Pulsars
, 2021 Millisecond pulsars in tight binaries have recently opened new challenges in our understanding of physical processes governing the evolution of binaries and the interaction between astrophysical plasma and electromagnetic fields. Transitional systems that showed changes from rotation-powered to accretion powered states and vice versa have bridged the ...

Research Notes of the AAS, 2023 Abstract Millisecond pulsars (MSP) are an important subclass of rotation powered pulsars (RPP), traditionally defined as those with P s < 20–30 ms and B s ≲ 1010 G.

PSR J1953+1844 Probably Being the Descendant of an Ultracompact X-Ray Binary
The Astrophysical Journal Letters, 2023 PSR J1953+1844 (i.e., M71E) is a millisecond pulsar in a 53 minute binary orbit discovered by the Five-hundred-meter Aperture Spherical radio Telescope. The mass function from pulsar timing is 2.3 × 10 ^−7 M _⊙ .
