A turn-up in pulsar spectra at mm-wavelengths?

KRAMER M., XILOURIS K.M., JESSNER A., WIELEBINSKI R. and TIMOFEEV M.

Abstract (from CDS):

We present the results of recent pulsar observations at frequencies between 27.9GHz and 34.8GHz, i.e. in a wavelength range of λ10.75mm to λ8.61mm, made with the Effelsberg radiotelescope. The measured flux densities of two out of eight detected pulsars suggest that the spectrum flattens out at high frequencies or even shows a turn-up. Moreover, we report variations in the measured flux densities on time scales of ten to thirty minutes.
