Applied Physics/Physics Colloquium

Topic: 
On the Measurement of Gravitational Waves from the Merger of two Black Holes

Venue: 
Hewlett 200
Speaker:

Abstract / Description: 

Over a billion years ago, a binary black hole system enjoyed its last few orbits and collided, releasing three solar masses worth of energy into vibrations of spacetime: gravitational waves.

​Towards the end of the summer of 2015, the ​LIGO team was wrapping up the final touches on the recent upgrades to their interferometers and getting it ready to run. Early in the morning on September 14th, those waves from a billion years ago rippled through the earth and were recorded by the LIGO detectors.

This is the story of those waves and detectors.


 

Held Tuesdays at 4:30 pm in the William R. Hewlett Teaching Center.

Refreshments in the lobby of Varian Physics at 4:15 pm.
