Estimating the Evolution of Sparks in the Partially Screened Gap of Pulsars from Subpulse Drifting
The Astrophysical Journal, 2023 A novel scheme has been developed to show that the observed phase behavior associated with subpulse drifting from two pulsars, J1034−3224 and J1720−2933, can be used to obtain the magnetic field configuration in the partially screened gap (PSG).

New limits on the photon mass with radio pulsars in the Magellanic clouds [PDF]
, 2016 A conservative constraint on the rest mass of the photon can be estimated under the assumption that the frequency dependence of dispersion from astronomical sources is mainly contributed by the nonzero photon mass effect. Photon mass limits have been set

Mode Changing in PSR B0844-35 and PSR B1758-29 with Enhanced Emission at the Profile Centers
The Astrophysical Journal, 2023 We have studied the single pulse emission from two pulsars, PSR B0844-35 and PSR B1758-29, over a wide frequency range of 300–750 MHz using the upgraded Giant Metrewave Radio Telescope.

Radio pulsar variability [PDF]
Proceedings of the International Astronomical Union, 2012 AbstractPulsars are potentially the most remarkable physical laboratories we will ever use. Although in many senses they are extremely clean systems there are a large number of instabilities and variabilities seen in the emission and rotation of pulsars.

X-RAY AND ROTATIONAL LUMINOSITY CORRELATION AND MAGNETIC HEATING OF RADIO PULSARS [PDF]
, 2016 Previous works have suggested a correlation between the X-ray luminosity and the rotational luminosity of radio pulsars. However, none of the obtained regression lines is statistically acceptable due to large scatter.

Radio pulsars in the Magellanic Clouds [PDF]
Symposium - International Astronomical Union, 1991 The Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC) have been searched for radio pulsars using the 64-m Parkes radiotelescope. The search has resulted in the discovery of four pulsars. Observed dispersion measures to each suggest that three lie in the Clouds (two in the LMC, one in the SMC) and that the fourth, which was found in the ...

The SUrvey for Pulsars and Extragalactic Radio Bursts – II. New FRB discoveries and their follow-up. [PDF]
, 2017 We report the discovery of four Fast Radio Bursts (FRBs) in the ongoing SUrvey for Pulsars and Extragalactic Radio Bursts at the Parkes Radio Telescope: FRBs 150610, 151206, 151230 and 160102.

New Mechanism of Pulsar Radio Emission [PDF]
Physical Review Letters, 2002 It is shown that pulsar radio emission can be generated effectively through a streaming motion in the polar-cap regions of a pulsar magnetosphere causing nonresonant growth of waves that can escape directly. As in other beam models, a relatively low-energy high-density beam is required. The instability generates quasi-transverse waves in a beam mode at

The specifics of pulsar radio emission
Open Astronomy, 2022 A characteristic property of pulsars is pulsed periodic radio emission, which has a high stability of periods. Despite the high stability of the emission periods of pulsars, monitoring the time of arrival of pulses (timing) shows the presence of ...
