Timing of Millisecond Pulsars in NGC 6752. III. On the Presence of Nonluminous Matter in the Cluster’s Core

The Astrophysical Journal
Millisecond pulsars are subject to accelerations in globular clusters (GCs) that manifest themselves in both the first and second spin period time derivatives, and can be used to explore the mass distribution of the potentials they inhabit.

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.

Investigating Unassociated Fermi-LAT sources for the search of Gamma ray pulsars including Millisecond pulsars using semicoherent approch [PDF]

EPJ Web of Conferences
The search for gamma-ray pulsars including millisecond pulsars (MSPs) among unassociated Fermi-Large Area Telescope (LAT) sources offers an opportunity to study these rapidly rotating, highly magnetized neutron stars.

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.

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.

Full polar cap cascade scenario: $\gamma$-ray and X-ray luminosities from spin-powered pulsars

, 1999
We modify polar cap cascade picture to include the ICS of the higher generation pairs. In such a ``full-cascade'' scenario, not only the perpendicular portion of the energy of the pairs goes to high energy radiation via SR, but the parallel portion of ...
