LECTURE – “Gravitational waves from the early Universe”

Who: Kari Rummukainen
When: Wednesday, February 7, 2018 at 12:15-13:15
Where: Danish IAS conference room

Professor of theoretical particle physics, University of Helsinki, Division of elementary particle physics

Violent events in the very early Universe, when its age was less than 10 picoseconds, may have
produced gravitational waves which can be observed in future space-based gravitational wave
observatories, like the LISA satellite constellation scheduled for launch in 2034. I discuss how
strong first order phase transitions produce gravitational waves, and how the signal can be used
to obtain information about beyond the Standard Model particle physics.
