Constraining Primordial Black Holes with the EDGES 21-cm Absorption Signal

The EDGES experiment has recently measured an anomalous global 21-cm spectrum due to hydrogen absorptions at redshifts of about z∼17. Model independently, the unusually low temperature of baryons probed by this observable sets strong constraints on any physical process that transfers energy into the...
