Polarimetric profiles of 27 millisecond pulsars

, 2004
We present high time resolution polarimetric profiles of 27 predominantly southern hemisphere millisecond pulsars, 15 of which have no previously published polarimetry.

A Systematic Search for Redback and Black Widow Candidates Based on the 4FGL-DR3 Unassociated Sources and the Zwicky Transient Facility Data

The Astrophysical Journal
Spider pulsars represent a unique subclass of radio millisecond pulsars in binaries, and are further categorized into black widows and redbacks according to the mass of the low-mass companion.

The first NenuFAR pulsar catalogue

Astronomy & Astrophysics
Context. The radio frequency range below 100 MHz has been unexplored until recently for extended pulsar population studies. We present the first low-frequency pulsar census of the northern sky with the NenuFAR radio telescope (10–85 MHz), performed ...

Deciphering Profile Stability in Millisecond Pulsars: Timescales, Frequency Evolution, and Implications on Emission Mechanisms

The Astrophysical Journal
Pulse profile stability in millisecond pulsars (MSPs) is a key factor in achieving high-precision timing essential for detecting nanohertz gravitational waves with pulsar timing arrays (PTAs).

Can Slow Pulsars in Milky Way Globular Clusters Form via Partial Recycling?

The Astrophysical Journal Letters
Alongside the population of several hundred radio millisecond pulsars currently known in Milky Way globular clusters, a subset of six slowly spinning pulsars (spin periods 0.3–4 s) are also observed.

Spin-orbit alignment hypothesis in millisecond pulsars

Astronomy & Astrophysics
Context. Millisecond pulsars (MSPs) are spun up during their accretion phase in a binary system. The exchange of angular momentum between the accretion disk and the star tends to align the spin and orbital angular momenta on a very short timescale ...

First Systematic Study Reporting the Changes in Eclipse Cutoff Frequency for Pulsar J1544+4937

The Astrophysical Journal
We present results from long-term monitoring of frequency-dependent eclipses of the radio emission from PSR J1544+4937, which is a black widow spider millisecond pulsar (MSP) in a compact binary system.

Transient Emission Phenomena in Millisecond Pulsars [PDF]

Millisecond pulsars are rapidly rotating neutron stars, with rotational periods on the order of milliseconds. The radio emission of millisecond pulsars exhibit a variety of interesting features such as bright transient bursts and rapid state changes ...

The GMRT High-resolution Southern Sky Survey for Pulsars and Transients. VIII. Orbital Variability and the Evolution of a 1 day He-WD Millisecond Pulsar J2101–4802

The Astrophysical Journal
We present timing and orbital phase-resolved polarimetry of the millisecond pulsar (MSP) J2101−4802, having a spin period of 9.48 ms and dispersion measure (DM) 25.05 pc cm ^−3 discovered with the Giant Meter Radio Telescope (GMRT).
