Physics Colloquium: Satoshi Tanioka

NOTICE: This event has been cancelled.

The Syracuse University Physics Department is pleased to present their very own Dr. Satoshi Tanioka, Post-Doctoral Researcher in the Gravitational Waves group.

Satoshi Tanioka is a postdoctoral researcher at Syracuse University. His research interests include precision laser interferometry, gravitational wave detection, experimental astrophysics, and low noise coatings. He completed his Ph.D. on cryogenic optical coatings at the Department of Astronomical Science, SOKENDAI in Toyko in 2021. He completed his BSc at the University of Toyko in 2016.

“Future Gravitational Wave Detectors or: How I Learned to Stop Worrying and Love the Coating”

Abstract:

The sensitivity of current gravitational wave detector (GWD) such as advanced LIGO (aLIGO) is partially limited by thermal noise arising from amorphous silica and titania-doped tantala coatings at their most sensitive frequency band. Future GWDs are planned to employ low thermal noise coatings so that one can explore further into the Universe with improved sensitivity. On the other hand, KAGRA, the gravitational wave detector in JAPAN, is going to reduce coating thermal noise by cooling down the mirrors. In his talk, Dr. Tanioka will introduce how we are trying to improve the coating, hence the GWDs.
