Abstract:
S147 is a large faint shell-type supernova remnant (SNR) known for its
remarkable spectral break at cm-wavelength, which is an important
physical property to characterize SNR evolution. However, the spectral
break is based on radio observations with limited precision.
New sensitive observations at high frequencies are required for a
detailed study of the spectral properties and the magnetic field
structure of S147.
Description:
We conducted new radio continuum and polarization observations of S147
at λ11cm and at λ6cm with the Effelsberg 100-m telescope
and the Urumqi 25-m telescope, respectively. We combined these new
data with published lower-frequency data from the Effelsberg 100-m
telescope, and with very high-frequency data from WMAP to investigate
the spectral turnover and polarization properties of S147.
