Primordial Black Hole Mass Function's Cosmological Impact Investigated in New Study

A recent preprint explores the cosmological implications of primordial black holes (PBHs) using an extended mass function. The research examines how early Universe thermal history could shape this function, potentially leaving observable imprints on cosmic structure formation and gravitational-wave astronomy. This work, though not yet peer-reviewed, contributes to understanding the universe's early evolution and dark matter candidates.
