Abstract
In this paper, the integrated continuum radio spectrum of supernova remnant
(SNR) W44 was analyzed up to 70 GHz, testing the different emission models
that can be responsible for its particular shape. The observations by the
Planck space telescope made it possible to analyze the high frequency part of
radio emission from SNRs. Although the quality of radio continuum spectrum (a
high scatter of data points at same frequencies) prevents us to make definite
conclusions, the possibility of spinning dust emission detection towards this
remnant is emphasized. In addition, a concave-down feature, due to
synchrotron losses, can not be definitely dismissed by the present knowledge
of the integrated radio continuum spectrum of this SNR.
