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. [Projekat

期刊介绍：
Serbian Astronomical Journal publishes original observations and researches in all branches of astronomy. The journal publishes:
Invited Reviews - review article on some up-to-date topic in astronomy, astrophysics and related fields (written upon invitation only),
Original Scientific Papers - article in which are presented previously unpublished author''s own scientific results,
Preliminary Reports - original scientific paper, but shorter in length and of preliminary nature,
Professional Papers - articles offering experience useful for the improvement of professional practice i.e. article describing methods and techniques, software, presenting observational data, etc.
In some cases the journal may publish other contributions, such as In Memoriam notes, Obituaries, Book Reviews, as well as Editorials, Addenda, Errata, Corrigenda, Retraction notes, etc.
