The detection of gravitational waves by LIGO signified the realisation of a decades long goal for more than a thousand researchers and heralded the beginning of a new age of astronomy and astrophysics. Three and a half years since first detection, LIGO has observed multiple black hole mergers and recently detected the merger of neutron stars that was subsequently observed across the electromagnetic spectrum.
This talk will discuss the future of gravitational wave detection including how LIGO sensitivity will be improved using advanced techniques such as squeezed light, and planned space-based interferometers such as LISA. Next month, the GRACE Follow-on mission will launch with a goal of mapping the Earth’s water using gravity measurements from space. With major contributions from Australia, including Lindfield CSIRO researchers, GRACE Follow-on will serve as the first test bed of LISA’s inter-spacecraft laser interferometry. The ANU team that worked on these projects are now sharing their measurement technology with the world through the Canberra startup company Liquid Instruments and their first product, Moku:Lab. This talk will tell the genesis story of Liquid Instruments and present their approach to next generation test and measurement instrumentation. |

Daniel Shaddock is a Professor in Physics at the Australian National University in Canberra. After completing his PhD at the ANU in 2001, he moved to NASA's Jet Propulsion Laboratory to work on the Laser Interferometer Space Antenna Mission where he served as NASA’s LISA Interferometer Architect. Now back at ANU, his research focusses on techniques for precision measurements using lasers and advanced signal processing. The applications of his research include ground and space-based gravitational wave detection, mapping the Earth’s gravity with satellites, tracking space debris in the Earth’s orbit, and free-space laser communications. Daniel is also the CEO and founder of Liquid Inst |
