Description

Primordial black holes (PBHs) constitute an attractive candidate for dark matter. I will describe a new generic mechanism for PBH formation from fragmentation of scalar fields. Then, I will revisit PBH formation from vacuum bubbles during inflation and show how resulting broad PBH mass-spectrum can simultaneously account for dark matter, reported HSC candidate, LIGO events as well as seeds of supermassive black holes. Finally, I will discuss how interactions with compact stars can shed light on small PBHs of "sublunar" mass that can compose all of the dark matter.
