The Radio-FIR Correlation in the Context of Deep Radio Source Counts
The episode discusses a paper titled "The Radio-FIR Correlation in the Context of Deep Radio Source Counts." The hosts explore how this work investigates the tension between radio source counts and infrared measurements of star formation rate density at high redshifts. They conclude that an evolving radio-FIR correlation parameter q(z), driven by changing cosmic ray losses due to magnetic field strengthening, is a strong physical mechanism to resolve this discrepancy.
