Nergis Mavalvala on the upcoming Advanced LIGO run


By Louise Mayor in Waterloo, Canada

The search for ripples in space–time known as gravitational waves is one of my favourite scientific endeavours. So here at the Perimeter Institute’s Convergence conference, I couldn’t miss the opportunity to talk to Nergis Mavalvala, one of the speakers here.

A physicist at MIT, Mavalvala works on the Laser Interferometer Gravitational-Wave Observatory (LIGO) in the US. LIGO’s first six observing runs took place from 2002 to 2010 and yielded no detection of a gravitational wave. Since then, LIGO physicists have been working on increasing the instrument’s sensitivity – they needed to make it even better at measuring the stretching and compressing of the interferometers’ 4 km-long arms thought to occur if a gravitational wave passes through them.

Five years on, LIGO’s $200m upgrade is now complete.
