Pulse broadening analysis for several new pulsars and anomalous scattering.

LEWANDOWSKI W., DEMBSKA M., KIJAK J. and KOWALINSKA M.

Abstract (from CDS):

We show the results of our analysis of the pulse broadening phenomenon in 25 pulsars at several frequencies using the data gathered with Giant Meterwave Radio Telescope and Effelsberg radiotelescopes. Twenty-two of these pulsars were not studied in that regard before and our work has increased the total number of pulsars with multi-frequency scattering measurements to almost 50, basically doubling the amount available so far. The majority of the pulsars we observed have high to very high dispersion measures (DM > 200) and our results confirm the suggestion of Löhmer et al. that the scatter time spectral indices for high-DM pulsars deviate from the value predicted by a single thin screen model with Kolmogorov's distribution of the density fluctuations. In this paper we discuss the possible explanations for such deviations.
