Cosmic Strings and Primordial Black Holes in the Era of Gravitational - Wave Astronomy
Presented by Dr. Mairi SAKELLARIADOU
Description
In the first part, I will present the most recent constraints on cosmic strings using the O3 LIGO/Virgo/KAGRA data. I will then briefly discuss gravitational memory and its consequences for the obtained constraints on the string tension. In the second part, I will address the question whether the LIGO/Virgo detected GWs from binary back hole coalescences are of PBH instead of astrophysical origin. I will conclude with a novel mechanism leading to PBH formation from collapsing cusps on cosmic string loops.
