Turn-over in pulsar spectra above 1 GHz
J. Kijak, Y. Gupta, K. Krzeszowski
We present the first direct evidence for turn-over in pulsar radio spectra at high frequencies. Two pulsars are now shown to have a turn-over frequency > 1GHz. We also find some ev…

Emission altitude in radio pulsars
J. Kijak
This paper presents a method of estimation of emission altitudes using observational data - precise measurements of pulse profile widths at low intensity level. The analysis of emi…

On the high frequency polarization of pulsar radio emission
A. von Hoensbroech, J. Kijak, A. Krawczyk
We have analyzed the polarization properties of pulsars at an observing frequency of 4.9 GHz. Together with low frequency data, we are able to trace polarization profiles over more…
