Clustered Primordial Black Holes and Stellar Bubbles from the Primordial Universenal waves

Webinar:- The speaker and his team explore the possibility of strongly clustered primordial black holes (PBHs). Such clustered PBHs may be produced by multi-stream inflation. Those PBH bubbles may produce gravitational waves possibly detectable by LISA, or themselves shine with optical signals like stars. Similar clustering mechanisms may be used to study bubbles with other exotic matter such as unstable particles, domain walls, cosmic strings or monopoles.

“Copernicus Webinar and Colloquium Series”: To promote scientific discussions during this pandemic, they are organizing an online seminar series, i.e. Copernicus Webinar Series, seeking the most outstanding speakers to introduce innovative ideas and important progress in the field of gravity and cosmology. This series is named after the famous Polish Astronomer, Nicolaus Copernicus, whose discovery eventually marked the dawn of modern science.
