Seminar:- Testing fundamental physics with gravitational wave propagations
The detection of gravitational waves from the LIGO/Virgo collaboration provides an excellent probe for the fundamental physics of gravity with interferometer detectors, and the recent Pulsar Timing Arrays(PTA) detections of
Stochastic Gravitational Wave Background(SGWB) open a new window due to their different frequency sensitivity (nHz band).
The speaker and his team explore the possibility of testing gravity theory using both interferometers and PTA detectors by studying the impacts of modified propagation of gravitational waves.
On the other hand, astrometry also holds the potential to detect SGWB by precisely measuring the stellar positions. The research team explores the feasibility of using astrometry for the identification of parity-violating signals which is hard in PTA measurements.
