Title: Gravitational Echoes from Primordial Black Holes
Abstract: Primordial black holes are a fascinating family of black holes that may have formed in the early universe and are considered a potential candidate for the dark matter. After briefly reviewing their formation mechanism, we examine their evolution throughout cosmic history and their possible role in explaining the nature of high-redshift compact sources known as Little Red Dots. Then, we explore their detectability via gravitational waves, by focusing on signals emitted both during their formation and from the merger of associated primordial binaries. Finally, we highlight potential smoking-gun signatures that could probe their existence in future gravitational wave observatories, such as the Einstein Telescope and LISA.
