Pulsar Radio Spectra—High Frequency Turnover

J. Kijak, Y. Gupta, K. Krzeszowski

Abstract


We present the first direct evidence for turnover in pulsar radio spectra at high frequencies. New data for some pulsars, taken with the GMRT, show the maximum flux in the spectrum to be ~ 1 GHz. We also find some evidence that this peak frequency of turnover in pulsar spectra appears to depend on dispersion measure and pulsar age.
