A small-size (less than 1 min of ARC) decametric radio source in the Perseus cluster

Results of observations of decametric radio emission from the Perseus cluster with the aid of URAN-1 interferometer are presented. The 42.2 km baseline of the interferometer is oriented along the parallel. The object is shown to contain a radio source with dimensions which do not exceed 60 sec and w...

Description
Summary:Results of observations of decametric radio emission from the Perseus cluster with the aid of URAN-1 interferometer are presented. The 42.2 km baseline of the interferometer is oriented along the parallel. The object is shown to contain a radio source with dimensions which do not exceed 60 sec and whose flux is not less than 95 Jy over the frequency range from 16.7 to 25 MHz. Several source models are considered and a comparison with higher-frequency measurements is carried out. It seems possible that the source is a component of 3C84A which was reportedly observed earlier by the interferometry technique at 408 and 1415 MHz.
