Predictions on the abundance of primordial black holes: results from the SMILE VLBI milli-lensing sample
Xinyue Jiang, Shuo Cao, Marek Biesiada +4
Primordial black holes (PBHs) formed in the early universe represent a well-motivated dark matter candidate. However, their abundance in the intermediate-to-high mass range (…
