Frequency-dependent Emission of the Millisecond Pulsar B1937+21 with the Parkes Ultrawideband Receiver

The Astrophysical Journal
In this study, we report on the broadband polarization behavior of the millisecond pulsar B1937+21 (J1939+2134), using high-quality observations made with the ultrawideband low receiver on Murriyang, the Parkes radio telescope.

The Anomalous Acceleration of PSR J2043+1711: Long-period Orbital Companion or Stellar Flyby?

The Astrophysical Journal
Based on the rate of change of its orbital period, PSR J2043+1711 has a substantial peculiar acceleration of 3.5 ± 0.8 mm s ^–1 yr ^–1 , which deviates from the acceleration predicted by equilibrium Milky Way (MW) models at a 4 σ level.

Exploring Unusual High-frequency Eclipses in MSP J1908+2105

The Astrophysical Journal
This 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

Are millisecond pulsars different than “Normal” pulsars? [PDF]

International Astronomical Union Colloquium, 1992
AbstractWhile millisecond pulsars have very different period parameters and a different evolutionary history compared to “normal” pulsars, the properties of their pulsed emission are remarkably similar to those of normal pulsars.

Pulse Jitter and Single-pulse Variability in Millisecond Pulsars

The Astrophysical Journal
Understanding the jitter noise resulting from single-pulse phase and shape variations is important for the detection of gravitational waves using pulsar timing arrays.

GRAVITATIONAL RADIATION FROM ACCRETING MILLISECOND PULSARS

The Eleventh Marcel Grossmann Meeting, 2008
It is widely assumed that the observed reduction of the magnetic field of millisecond pulsars can be connected to the accretion phase during which the pulsar is spun up by mass accretion from a companion. A wide variety of reduction mechanisms have been proposed, including the burial of the field by a magnetic mountain, formed when the accreted matter ...
