LOW-LEVEL RADIO EMISSION FROM RADIO GALAXIES AND IMPLICATIONS FOR THE LARGE SCALE STRUCTURE

摘要: We present an update on our proposal that during the 'quasar era' (1:5 ≲ z 3), powerful radio galaxies could have played a major role in enhanced global star-formation, and widespread magnetization metal pollution of universe. A key ingredient this is estimate true cosmological evolution galaxy population likely to be even steeper than what has been inferred from flux-limited samples sources with redshift data, when allowance made for inverse Compton losses cosmic microwave background which were much greater at higher redshifts. thus large fraction clumps proto-galactic material within web laments was probably impacted by expanding lobes quasar era. Some recently published observational evidence simulations provide support picture are pointed out. also show x-ray emission era, we largely missing derived luminosity function, still only small observed soft background (XRB) hence limit imposed scenario XRB not violated.
