Avneet Singh is a new PhD research fellow at BCCR (GFI, Nansen Centre) working on data assimilation methods in strongly coupled earth systems. Avneet obtained his doctorate in Astrophysics from the Max Planck Institute for Gravitational Physics in 2017 where he continued as a postdoctoral fellow before joining GFI in Jan 2019. In his previous life as an astrophysicist, he worked for the Einstein@Home project and the LIGO Scientific Collaboration, searching for Neutron stars in deep space by observing their gravitational spectrum.
In 1915, Albert Einstein postulated the existence of Gravitational Waves (GW), ripples in the fabric of spacetime traveling at the speed of light, long thought to be emitted at detectable magnitudes only by some of the most violent events in the universe. On Sept 14 2015, precisely 100 years after Einstein's prediction, the world of astrophysics was pushed into a new era with the first direct observation of gravitational waves (GW150914, Nobel Prize in Physics 2017) by the twin aLIGO detectors. In this talk, we'll walk through the past and present of gravitational waves, and their incredible importance in humanity's quest for deep space exploration, as deep and far back in time as the very birth of cosmos.
