Radio emission of the group of stars in the Aquarius and Cetus constellations

Abstract

In the present work, the optical identification of a group of radio sources located in the Aquarius and Cetus constellations in a field with the size of 1.2 square degrees has been carried out. Ten radio sources under investigation were identified with stars and one object was identified with a diffuse image (ESO-538-10). It should be stressed that eight radio objects were found to have a non-thermal radio spectrum. This fact is likely to indicate the presence of the significant magnetic field in the atmosphere of the sources. Precise radio and optical coordinates of the identified objects were suggested. Significant radio refraction in the interstellar medium in the tested space direction was revealed.
