How far back in time is this image? Is it in the early stages of the universe and this is why the large concentration of black hole?

If we assume that the host galaxy of these 2 radio lobes lies in between the lobes (SDSS J102035.50+221415.9), then the photometric redshift is approximately 0.73. This translates to roughly 6.5 billion years ago. You can check out the SDSS observations of this subject by clicking on the SDSS link beneath the image in Radio Talk.
