DETERMINATION OF THE ROTATION MEASURE VALUE SIGN WHEN RECEIVING A SINGLE LINEAR POLARIZATION OF THE PULSAR RADIO EMISSION [PDF]
Radio Physics and Radio Astronomy, 2020 Purpose: The studies of pulsars allow enriching our knowledge in determination of parameters of both the exotic electron-positron plasma in the pulsar magnetosphere with strong magnetic field and the ordinary ion-electron plasma of the interstellar ...

Constraints on the Helium Abundance from Fast Radio Bursts
Universe, 2022 Through the relationship between dispersion measures (DM) and redshifts, fast radio bursts (FRBs) are considered to be very promising cosmological probes. In this paper, we attempted to use the DM-z relationship of FRBs to study the helium abundance (YHe)

Dispersion measures and dispersive orderings [PDF]
Statistics & Probability Letters, 2003 In this paper, the comparison of random variables according to the functionals of a general class of dispersion measures is characterized in terms of the dilation order. The Gini's mean difference is a particular member of this general class. In addition, a new and weaker order, called the second-order absolute Lorenz ordering, is introduced, and we ...

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 ...

Measures Minimizing Regularized Dispersion [PDF]
Journal of Scientific Computing, 2018 We consider a continuous extension of a regularized version of the minimax, or dispersion , criterion widely used in space-filling design for computer experiments and quasi-Monte Carlo methods. We show that the criterion is convex for a certain range of the regularization parameter (depending on space dimension) and give a necessary and sufficient ...

Bounding the photon mass with cosmological propagation of fast radio bursts
Physics Letters B, 2021 Photon is the fundamental quantum of electromagnetic fields, whose mass, mγ, should be strictly zero in Maxwell's theory. But not all theories adopt this hypothesis.

Dispersion Measurement with Optical Computing Optical Coherence Tomography
Photonics, 2022 We propose a novel technique to measure fiber dispersion without any derivative operation and index measurement. Based on the relationship between the dispersion and the signal in optical computing optical coherence tomography, dispersion can be deduced ...
