Constraining the magnetic field geometry of the millisecond pulsar PSR~J0030+0451 from joint radio, thermal X-ray and -ray emission
J. Pétri, S. Guillot, L. Guillemot +13
With the advent of multi-wavelength electromagnetic observations of neutron stars, spanning many decades in photon energies, from radio wavelengths up to X-rays and -rays, it be…
Pulsar Scintillation Studies with LOFAR: II. Dual-frequency scattering study of PSR J0826+2637 with LOFAR and NenuFAR
Ziwei Wu, William A. Coles, Joris P. W. Verbiest +28
Interstellar scattering (ISS) of radio pulsar emission can be used as a probe of the ionised interstellar medium (IISM) and causes corruptions in pulsar timing experiments. Two typ…
Free-free absorption parameters of Cassiopeia A from low-frequency interferometric observations
Lev A. Stanislavsky, Igor N. Bubnov, Aleksander A. Konovalenko +2
Context. Cassiopeia A is one of the most extensively studied supernova remnants (SNRs) in our Galaxy. The analysis of its spectral features with the help of low frequency observati…
Radio Pulsar Beam Geometry at Lower Frequencies: Bright Sources Outside the Arecibo Sky
Joanna M. Rankin
We present pulsar emission beam analyses and models in an effort to examine pulsar geometry and physics at the lowest frequencies scattering permits. We consider two populations of…
The second decametre pulsar census at UTR-2 radio telescope
Ihor P. Kravtsov, Vyacheslav V. Zakharenko, Oleg M. Ulyanov +3
Our paper presents the results of the second census of pulsars in decametre wave range at UTR-2 radio telescope. Over the past ten years, the number of discovered nearby pulsars in…
Dual-frequency single-pulse study of PSR B0950+08
A. V. Bilous, J. M. Griessmeier, T. Pennucci +33
PSR B0950+08 is a bright non-recycled pulsar whose single-pulse fluence variability is reportedly large. Based on observations at two widely separated frequencies, 55 MHz (NenuFAR)…
Super-Eddington accretion in the Q2237+0305 quasar?
L. A. Berdina, V. S. Tsvetkova, V. M. Shulga
The interband time lags between the flux variations of the Q2237+0305 quasar have been determined from light curves in the Johnson-Cousins V, R, and I spectral bands. The values of…
Resonance nonlinear reflection from neutron star and additional radiation components of Crab pulsar
V. M. Kontorovich, I. S. Spevak, V. K. Gavrikov
Additional high-frequency components of the pulsar radiation in Crab Nebula are considered as a result of the resonance with the surface electromagnetic wave at nonlinear reflectio…
Nonlinear reflection from the surface of neutron stars and puzzles of radio emission from the pulsar in the Crab nebula
Victor M. Kontorovich
Having no any explanations the radiation of high-frequency components of the pulsar in the Crab Nebula can be a manifestation of instability in the nonlinear reflection from the ne…
Two-fluid model of the pulsar magnetosphere represented as an axisymmetric force-free dipole
S. A. Petrova
Based on the exact dipolar solution of the pulsar equation the self-consistent two-fluid model of the pulsar magnetosphere is developed. We concentrate on the low-mass limit of the…
A novel look at the pulsar force-free magnetosphere
S. A. Petrova
The stationary axisymmetric force-free magnetosphere of a pulsar is considered. We present an exact dipolar solution of the pulsar equation, construct the magnetospheric model on i…
Physics of radio emission in gamma-ray pulsars
S. A. Petrova
Propagation of radio emission in pulsar magnetosphere is reviewed. The effects of polarization transfer, induced scattering and reprocessing to high energies are analysed with an e…
Detection of the fine structure of the pulsar J0953+0755 radio emission in the decametre wave range
O. M. Ulyanov, A. O. Skoryk, A. I. Shevtsova +2
In this paper the anomalous intense pulse of the PSR J0953+0755 was studied in decametre wavelength range. For this pulse two scales of fine structure were discovered. The long-sca…
Axisymmetric force-free magnetosphere of a pulsar. II. Transition from the self-consistent two-fluid model
S. A. Petrova
The self-consistent two-fluid model of the pulsar magnetosphere is considered. We concentrate on the case of vanishingly small inertia of the particles. Our approach allows to obta…
Global structure of the pulsar force-free magnetosphere revisited
S. A. Petrova
A new model of the pulsar force-free magnetosphere is suggested, which includes the presence of the polar, outer and slot gaps. It is based on a new exact solution of the pulsar eq…
On the Global Structure of Pulsar Force-free Magnetosphere
S. A. Petrova
The dipolar magnetic field structure of the neutron star is modified by the plasma originating in the pulsar magnetopshere. In the simplest case of a stationary axisymmetric force-…
Axisymmetric force-free magnetosphere of a pulsar. I. The structure close to the magnetic axis
S. A. Petrova
The stationary axisymmetric force-free magnetosphere of a pulsar is studied analytically. The pulsar equation is solved in the region close to the magnetic axis. Proceeding from li…
A new interpretation of Giant radio pulses from the Crab pulsar
N. Lewandowska, C. Wendel, V. Kondratiev +2
The Crab pulsar experienced a major flare in 2010 as observed by Fermi LAT. Observations by the Hubble Space Telescope indicate that the flare was accompanied by a structural chang…
