Title: Charting the Universe with Primordial Black Holes: From Sub-solar to Supermassive
Abstract: The detection of compact binary mergers with sub-solar masses at gravitational wave observatories would mark a groundbreaking discovery of primordial black holes (PBHs). Concurrently, evidence for a nano-Hz stochastic gravitational wave background observed by pulsar timing arrays could suggest a non-astrophysical origin, potentially arising from scalar-induced gravitational waves. First, I will explore the interplay between these phenomena, focusing on sub-solar PBH populations within reach of upcoming experiments. In the second part, I will shift the focus to supermassive PBHs, presenting novel constraints derived from large-scale structure observations.
