Highly sensitive studies of interstellar medium in direction towards a given sample of pulsars will be performed. The characteristics of diffuse interstellar gas such as dispersion measures, emission measures, electron densities, electron temperatures will be obtained by processing the obtained data sets. A cross-correlation analysis of characteristics of the same medium, which manifest themselves differently in different types of radio emission, will allow us to clarify the physical parameters of this medium, to estimate the contribution of cold plasma to the total electron density on the line of sight. A method for clarifying the physical parameters of galactic HII regions lying on the line of sight in direction of pulsars, using the dispersion measure delays inside the HII regions, will also be proposed and investigated. popup.nrat_date 2025-07-07 Close
