Modeling the radio background from the first black holes at cosmic dawn: Implications for the 21 cm absorption amplitude
We estimate the 21 cm radio background from accretion onto the first intermediate-mass black holes between z ≈ 30 and z ≈ 16. Combining potentially optimistic, but plausible, scenarios for black hole formation and growth with empirical correlations between luminosity and radio emission observed in l...
