Speaker

Dr Ryusuke Jinno (DESY)

Description

In the upcoming decades, gravitational waves (GWs) will be an important tool in probing the early Universe and in testing high energy physics. In this lecture I will review GW production in cosmological first-order phase transitions, putting more emphasis on analytic understanding of the process. The structure of the lecture will be:
- Basics of GW production in the early Universe
- GW production in first-order phase transitions: conditions for producing large amount GWs & particle models satisfying these conditions
- Three GW sources in first-order phase transitions: bubble collisions, sound waves, turbulence
- Towards better prediction of the signal: analytic vs. numerical
- Recent hot topic(s)
