Trosolwyg

I am an experimental physicist in gravitational-wave detector science. Since the monumental first detection of gravitational waves from a binary black hole merger in 2015, followed by a neutron star merger in 2017, it has been a golden age of gravitational-wave astrophysics. The gravitational wave detectors are laser interferometers to detect distortions of space-time caused by gravitational waves, coming from somewhere in the universe. Because the distortions of space-time are extremely small, typically an order of 10^(-21) m (0.000...21 zeros... 001 m, one-millionth of a proton diameter), the gravitational-wave detectors are extremely sensitive, as precise as Heisenberg’s uncertainty limit allows. I worked on the two large-scale detectors, LIGO Livingston detector and KAGRA detector to make the detector work and improve the sensitivity to run the astrophysical observations. Because the instruments must be very sensitive, many state-of-the-art technologies are being developed and implemented. Currently, at Cardiff, I work on new technologies to make future detectors more sensitive. We want to observe more numbers of black hole or neutron star mergers from even the father universe.
