AP 483 Seminar

Organized by Stanford OSA/SPIE Student Chapter

Refreshments at 4 PM


Abstract: What might the future of the LIGO detectors look like? Although the interferometers are not yet at design sensitivity, Advanced LIGO has already detected gravitational waves from merging black holes and from merging neutron stars. And the future looks bright - many improvements are now underway as we push the detectors towards design sensitivity. Exotic plans for squeezed light, new optical coatings, low temperature silicon optics, and even new facilities are now being discussed in the community. I will discuss some of the ideas being pursued, and highlight the work Stanford is doing to open up this new field of astronomy.


 Biography: Dr. Brian Lantz is a Senior Research Scientist in the Byer/Fejer group. He started working on LIGO in 1991 as an undergraduate in Rai Weiss's lab at MIT, and stayed there for his Ph.D. He was the lead scientist for the Advanced LIGO seismic isolation system and now serves as the Advanced Detector Chair for the LIGO Scientific Collaboration.
