The analysis of the largest sample of multifrequency pulsar scatter time estimates.

LEWANDOWSKI W., KOWALINSKA M. and KIJAK J.

Abstract (from CDS):

We present our results of pulse broadening time estimates and the study of the frequency scaling of this quantity for 60 pulsars based on actual multifrequency scattering estimates. This research was based on our own measurements, performed on the observational data and the profiles from various pulsar profile data bases, as well as the scatter time measurements that were found in the literature. We were able to construct a data base of over 60 pulsars with true multifrequency α measurements, which allowed us to revise the previously proposed relations between the scatter time spectral slope and the dispersion measure (DM). We found that the deviations from theoretical predictions of the value of α appear for pulsars regardless of their DM, however, the DM-averaged value of the scaling index is almost constant except for pulsars with very high DMs. Based on the obtained slopes we were also able to estimate the amount of scattering at the standard frequency of 1 GHz. We found that while the estimated standardized pulse broadening time increases with DM the relation seems to be much flatter than it was previously proposed, which suggests higher values of the scatter time for mid-DM pulsars, and lower values of expected pulse broadening for highly dispersed sources.
