Fast radio bursts as giant pulses from young rapidly rotating pulsars [PDF]
, 2016 We discuss possible association of fast radio bursts (FRBs) with supergiant pulses emitted by young pulsars (ages $\sim$ tens to hundreds of years) born with regular magnetic field but very short -- few milliseconds -- spin periods.

Observations of the gamma-ray pulsar J1836+5925 at 111 MHz
Open Astronomy, 2021 We describe the 10-day radio observations of the gamma-ray pulsar J1836+5925. Observations were carried out in the Pushchino Radio Astronomical Observatory at the frequency of 111 MHz using the Large Phased Array of the Lebedev Physical Institute.

Multi-Messenger Astrophysics of a Millisecond Pulsar Orbiting around a Massive Black Hole
Universe, 2022 Extreme-mass-ratio and intermediate-mass-ratio binaries with a millisecond pulsar are gravitational-wave sources that emit also electromagnetic radiation.

Polarimetry of 600 pulsars from observations at 1.4 GHz with the Parkes radio telescope [PDF]
, 2017 Over the past 13 years, the Parkes radio telescope has observed a large number of pulsars using digital filterbank backends with high time and frequency resolution and the capability for Stokes recording.

Pulsar wind nebulae created by fast-moving pulsars [PDF]
Journal of Plasma Physics, 2017 We review multiwavelength properties of pulsar wind nebulae created by supersonically moving pulsars and the effects of pulsar motion on the pulsar wind nebulae morphologies and the ambient medium.

Gravitational waves from pulsars in the context of magnetic ellipticity
European Physical Journal C: Particles and Fields, 2017 In one of our previous articles we have considered the role of a time dependent magnetic ellipticity on the pulsars’ braking indices and on the putative gravitational waves these objects can emit.

Post-main-sequence planetary system evolution [PDF]
Royal Society Open Science, 2016 The fates of planetary systems provide unassailable insights into their formation and represent rich cross-disciplinary dynamical laboratories. Mounting observations of post-main-sequence planetary systems necessitate a complementary level of theoretical

Dealing with the data imbalance problem on pulsar candidates sifting based on feature selection [PDF]
Research in Astronomy and Astrophysics, 2024, 2023 Pulsar detection has become an active research topic in radio astronomy recently. One of the essential procedures for pulsar detection is pulsar candidate sifting (PCS), a procedure of finding out the potential pulsar signals in a survey. However, pulsar candidates are always class-imbalanced, as most candidates are non-pulsars such as RFI and only a ...

Timing analysis for 20 millisecond pulsars in the Parkes Pulsar Timing Array [PDF]
, 2015 We present timing models for 20 millisecond pulsars in the Parkes Pulsar Timing Array. The precision of the parameter measurements in these models has been improved over earlier results by using longer data sets and modelling the non-stationary noise. We
