| Abstract: | Results of observations of the five candidate GPS sources J0626+8202, J0726+7911, J1044+8054, J1823+7938, and J1935+8130 are
presented. GPS sources are extragalactic sources whose spectral peaks are near several GHz. These objects were observed on
the RATAN-600 radio telescope from 1999 through 2010 at 1.1, 2.3, 4.8, 7.7, 11.2, and 21.7 GHz. These radio sources were selected
from a complete sample (S
v
≥ 200 mJy at 1.4 GHz) in the vicinity of the North Celestial Pole (+75° ≤ δ ≤ +88°); four are considered as GPS candidates for the first time here. Their spectral properties, variability and morphology
are analyzed, and confirms that these can be classified as GPS sources. These four to five GPS sources probably comprise a
complete sample of this class of object in this region of the celestial sphere. |
