Abstract: | The traces of a radio jet from the NGC 1275 galaxy nucleus are revealed in position angle (PA) +45° using the data of published observations at 18, 20, and 73 cm wavelengths. The jet has a distorted form and is seen at 6–7 distance from the nucleus where its PA=+20°. It is shown that the optical detail situated 7 north-east from the nucleus of the galaxy is projected exactly on the trace of the radio jet. It is supposed that the radio jet is connected with this optical detail, a group of stars. One may compare theree radio jets in the circumstellar region of the NGC 1275 galaxy: the youngest in PA=149°, the older in PA=–15° and +145° with the centres of star formations in a 6 circumnuclear region. Their ages differ as the ages of corresponding radio jets. |
