    • Evaporating primordial black holes as varying dark energy 
      Nesseris, Savvas; Sapone, Domenico; Sypsas, Spyros (Elsevier, 2020)
      If light enough primordial black holes (PBH) account for dark matter, then its density decreases with time as they lose mass via Hawking radiation. We show that this time-dependence of the matter density can be formulated ...
