Modelling of radio supernovae: Including the effects of inhomogeneities and radiative cooling
Claes-I. Bjornsson
The presence of inhomogeneities in a spatially unresolved source is often hard to establish. This limits the accuracy with which the source properties can be determined. It is show…
The radio spectra of SN 2020oi: Effects of radiative cooling on the deduced source properties
C. -I. Bjornsson
Observations of radiative cooling in a synchrotron source offer a possibility to further constrain its properties. Inverse Compton cooling is indicated in the radio spectra during…
Implications of the low frequency turn-over in the spectrum of radio knot C in DG Tau
Claes-I. Bjornsson
The synchrotron spectrum of radio knot C in the protostellar object DG Tau has a low frequency turn-over. This is used to show that its magnetic field strength is likely to be at l…
Joining radio with X-rays: A revised model for SN 1993J
Claes-I. Bjornsson
A joint analysis is done of the radio and X-ray observations of SN 1993J. It is argued that neither synchrotron cooling behind the forward shock nor thermal cooling behind the reve…
The location of the Crab pulsar emission region: Restrictions on synchrotron emission models
C. -I. Björnsson, A. Sandberg, J. Sollerman
Recent observations of the Crab pulsar show no evidence for a spectral break in the infrared regime. It is argued that the observations are consistent with a power-law spectrum in…
GRB 060218: The nature of the optical-UV component
C. -I. Björnsson
The optical-UV component in GRB 060218 is assumed to be due to optically thick cyclotron emission. The key aspect of this model is the high temperature of the absorbing electrons.…
