Welcome to RGZ, Maksimen!

I see two faint radio sources in this field, one in the center and one to the right, somewhat above center. Both are approximately circular in shape. That usually means they are radio emission from the center of a host galaxy (the "core"), or the hotspots of a (pair of) lobe(s). In either case, any jets are invisible.

If a much "deeper" radio image were taken of this field - one which could show much fainter radio emission - it might show one or more jets. However, it's also possible that any jets associated with either radio source have long since 'switched off', particularly if these two sources are lobe hotspots. Also, if the radio sources are cores, it's possible the jets are very short, too short to show up in a radio image with this resolution.

Hope this helps, and happy hunting! 😃
