Constraining the early universe with primordial black holes

13 May 2015

Time: 9:41am
Venue: G. O. Jones 516
Series: 
The London Relativity and Cosmology Seminar
Speaker: 
Sam Young (Sussex)
 
Abstract: 

Primordial black holes (PBHs) could have formed very early on in the history of the universe after inflation ended. They are a viable dark matter candidate and represent a unique probe to study the small scales of the early universe, not visible by other means. I will discuss how PBHs have been used to constrain the small scales, and how this depends strongly on the non-Gaussianity parameters, as well as how PBHs can be used to constrain the large scales in the early universe.
