Physics and Astronomy Colloquium
=93Gravitational Waves from Cosmological Sources=94
Xavier Siemens University of Wisconsin-Milwaukee
In this talk I will discuss gravitational wave production by early universe sources. I will give an introduction to gravitational waves and describe how we may detect them using laser interferometers. I will also describe how we may detect gravitational waves using pulsars as very stable clocks--a technique known as pulsar timing. I will then discuss the gravitational waves produced by a network of cosmic strings, and other mechanisms for gravitational wave generation in the early universe.
Refreshments at 2:30 PM in Burden Lounge, Anderson 108
