On the galactic distributions of radio pulsars and plasma density

Abstract: A brief review of distance measurement methods for some astronomical sources is presented. Galactic plasma density distribution as related to the distribution of radio pulsars is discussed and a method for constructing relations between dispersion measure and distance for Galactic radio pulsars in small solid angle intervals is described. Dispersion measure-distance relations for radio pulsars based on this approach in the Galactic longitude and latitude intervals of ∆l = 0 • ± 2 • and ∆b = 0 • ± 2 • are displ… Show more

“…The number of radio pulsars in the longitude interval Δℓ = 78-90 degrees with b = 0±2 degrees is only three, therefore, we have only checked the possible distances of these pulsars without making a fit. Some basic criteria based on observational results are listed below to construct distance versus DM relations (Ankay et al 2016). We assume that the main contribution to the measured DM values is mainly due to the plasma in the HII regions, SNRs and probably the Galactic central region.…”

“…In this work, we present an improved version of a basic and reliable method to determine distances of all radio pulsars with known dispersion measure (DM) values based on constructing distance -DM relations (Yazgan et al 2007;Ankay et al 2016). It is possible ★ E-mail: pinarkutukcu@gmail.com to derive average free electron densities in the line of sight (LOS) of the radio pulsars from these relations to constrain the distributions of the plasma as well as the radio pulsars in the Galaxy.…”
