Spectral properties of 441 radio pulsars |
by Simon Johnston (CASS) |
Swinburne student Fabian Jankowski and collaborators have presented the spectral properties of 441 pulsars using observations made with the Parkes radio telescope. They show that most (80%) pulsars have power-law spectra with a mean spectral index of -1.6. The remaining 20% show a variety of behaviour with some examples shown in the Figure. Reference: F.
