Unveiling Low-frequency Eclipses in Spider Millisecond Pulsars Using Wideband GMRT Observations

The Astrophysical Journal
Eclipses of radio emission have been reported for ∼58 spider millisecond pulsars (MSPs), of which only around 19% have been extensively studied. Such studies at low frequencies are crucial for probing the properties of the eclipse medium.

Probing neutron star physics using accreting neutron stars

EPJ Web of Conferences, 2010
We give an obervational overview of the accreting neutron stars systems as probes of neutron star physics. In particular we focus on the results obtained from the periodic timing of accreting millisecond X-ray pulsars in outburst and from the ...

Gamma rays from hidden millisecond pulsars [PDF]

, 1992
The properties were studied of a new class of gamma ray sources consisting of millisecond pulsars totally or partially surrounded by evaporating material from irradiated companion stars.

Single Millisecond Pulsars from Dynamical Interaction Processes in Dense Star Clusters

The Astrophysical Journal
Globular clusters (GCs) are particularly efficient at forming millisecond pulsars. Among these pulsars, about half lack a companion star, a significantly higher fraction than in the Galactic field.

Multiwavelength Evidence for Two New Candidate Transitional Millisecond Pulsars in the Subluminous Disk State: 4FGL J0639.1-8009 and 4FGL J1824.2+1231

The Astrophysical Journal
We report the discovery of two new Galactic accreting compact objects consistent with the respective positions of the unassociated Fermi-LAT γ -ray sources 4FGL J0639.1-8009 and 4FGL J1824.2+1231. A combination of new and archival X-ray data from Chandra,

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.

Follow-up Timing of Two Binary Pulsars with Massive White Dwarfs Discovered in Commensal Radio Astronomy FAST Survey

The Astrophysical Journal
We present phase-connected timing solutions, total-intensity and polarized profiles for two newly discovered pulsars, PSRs J1929+4105 and J2359+4239, identified by the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in the Commensal Radio ...
