A decade of transitional millisecond pulsars [PDF]

, 2018
Transitional millisecond pulsars (tMSPs), which are systems that harbor a pulsar in the throes of the recycling process, have emerged as a new source class since the discovery of the first such system a decade ago.

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.

On the aberration–retardation effects in pulsars [PDF]

, 2009
The magnetospheric locations of pulsar radio emission region are not well known. The actual form of the so-called radius-to-frequency mapping should be reflected in the aberration-retardation (A/R) effects that shift and/or delay the photons depending on

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

Growth of magnetic fields in accreting millisecond pulsars [PDF]

, 2013
R-modes can generate strong magnetic fields in the core of accreting millisecond neutron stars. The diffusion of these fields outside the core causes the growth of the external magnetic field and thus it affects the evolution of the spin-down rates dot{P}

Discovery of four binary millisecond pulsars [PDF]

, 1996
We present detailed parameters for four binary millisecond pulsars discovered during a survey of the southern sky with the Parkes radio telescope. Subsequent observations using the Parkes and Jodrell Bank radio telescopes have determined that the 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.

Millisecond pulsars cannot account for the inner Galaxy’s GeV excess [PDF]

, 2013
Using data from the Fermi Gamma-Ray Space Telescope, a spatially extended component of gamma rays has been identified from the direction of the Galactic center, peaking at energies of ∼2–3  GeV.

Observations of millisecond pulsars at 8.35 GHz [PDF]

, 2003
New pulsar observations at 8.35 GHz with the newly built highly sensitive receiver of the Effelsberg 100-m Radio Telescope are reported. They resulted in the first detection of 3 millisecond pulsars J1713+0747, B1855+09 and J2145-0750 at this high ...
