Aspect angle for interstellar magnetic field in SN 1006
O. Petruk, G. Dubner, G. Castelletti +6
A number of important processes taking place around strong shocks in supernova remnants (SNRs) depend on the shock obliquity. The measured synchrotron flux is a function of the asp…
The low frequency radio emission and spectrum of the extended SNR W44: new VLA observations at 74 and 324 MHz
G. Castelletti, G. Dubner, C. Brogan +1
We present new Very Large Array (VLA) radio images at 74 and 324 MHz of the SNR W44. The VLA images, obtained with unprecedented angular resolution and sensitivity for such low fre…
New VLA observations of the SNR Puppis A: the radio properties and the correlatoin withe the X-ray emission
G. Castelletti, G. Dubner, K. Golap +1
In this paper we report on a new study of the SNR Puppis A based on VLA observations at 1425 MHz; the improvement represents a factor of two in angular resolution and almost ten ti…
A multi-frequency study of the spectral index distribution in the SNR CTB 80
G. Castelletti, G. Dubner
We have conducted a study at radio wavelengths of the spectral behaviour of the supernova remnant (SNR) CTB 80. Based on an homogenised data set of integrated flux densities, we ca…
