Cosmic Ray production in SNRs of Pulsar Wind Nebulae type at different ages [PDF]
EPJ Web of Conferences, 2022 The overall observations of plerions from radio to the very high energy gamma-rays could provide information about the evolution of PWN from the young Crab-like to the older stages. The extended MeV-TeV emission from Geminga middle-aged pulsar of ~ 3.4 ×

What Makes the Crab Pulsar Shine? [PDF]
AIP Conference Proceedings, 2008 Our high time resolution observations of individual pulses from the Crab pulsar show that the main pulse and interpulse differ in temporal behavior, spectral behavior, polarization and dispersion. The main pulse properties are consistent with one current model of pulsar radio emission, namely, soliton collapse in strong plasma turbulence.

Insight-HXMT observations of the Crab pulsar [PDF]
Research in Astronomy and Astrophysics, 2019 We report on X-ray emission properties of the Crab pulsar (PSR B0531+21) using observations by insight-HXMT during its first year after launch. We obtained high signal-to-noise profiles in the X-ray energy band 11–250 keV.

On the Escape of Low-frequency Waves from Magnetospheres of Neutron Stars
The Astrophysical Journal, 2023 We study the nonlinear decay of the fast magnetosonic (fms) into the Alfvén waves in relativistic force-free magnetohydrodynamics. The work has been motivated by models of pulsar radio emission and fast radio bursts (FRBs), in which the emission is ...

Proper Motion of the Crab Pulsar Revisited [PDF]
The Astrophysical Journal, 2006 It has been suggested that the Crab pulsar's proper motion is well aligned with the symmetry axis of the pulsar wind nebula. We have re-visited this question, examining over 6 years of F547M WFPC2 chip 3 images to obtain a best-fit value of $ _\ast = 14.9 \pm 0.8$mas/yr at PA $278\arcdeg \pm 3\arcdeg$.

Characterization of the timing noise of the Crab pulsar [PDF]
Monthly Notices of the Royal Astronomical Society, 2003 We present a power spectral analysis of the Crab pulsar's timing noise, mainly using radio measurements from Jodrell Bank taken over the period 1982-1989. The power spectral analysis is complicated by nonuniform data sampling and the presence of a steep red power spectrum that can distort power spectra measurement by causing severe power ``leakage ...

Did the Crab Pulsar Undergo a Small Glitch in 2006 late March/early April? [PDF]
ApJ, Vol 826, Page 187, 2016, 2016 On 2006 August 23 the Crab Pulsar underwent a glitch, that was reported by the Jodrell Bank and the Xinjiang radio observatories. Neither data are available to the public. However, the Jodrell group publishes monthly arrival times of the Crab Pulsar pulse (their actual observations are done daily), using which it is shown that about five months earlier,

Observations of Radio Magnetars with the Deep Space Network
Advances in Astronomy, Volume 2019, Issue 1, 2019., 2019 The Deep Space Network (DSN) is a worldwide array of radio telescopes which supports NASA’s interplanetary spacecraft missions. When the DSN antennas are not communicating with spacecraft, they provide a valuable resource for performing observations of radio magnetars, searches for new pulsars at the Galactic Center, and additional pulsar‐related ...

CONNECTION OF ADDITIONAL PULSAR EMISSION COMPONENTS IN THE CRAB WITH THE RESONANCE REFLECTION FROM A NEUTRON STAR [PDF]
Radio Physics and Radio Astronomy, 2018 Purpose: The subject of the paper is discussion of reflected radiation from the neutron star surface. Such radiation, as was shown earlier by S. V. Trofymenko and one of the authors, occurs when reflects the radiation of relativistic positrons flying ...
