Sheila
Rowan explains the nature of gravitational waves, where they come from,
how we detected them, and what the future of this new era in astronomy
might look like.

A
century ago, Albert Einstein realised that in his new model for space
and time in our Universe (his 'General Theory of Relativity'), space
could be stretching and squashing in response to the motion of objects.
These ripples in space-time - 'Gravitational waves' - are produced by
some of the most energetic and dramatic phenomena in our universe,
including black holes, neutron stars and supernovae.
Close to 100
years after the prediction of the existence of gravitational waves, the
advanced detectors of the Laser Interferometer Gravitational-wave
Observatory (LIGO) recently detected such signals for the first time,
starting a new era in astronomy. Sheila Rowan explains the nature of
gravitational waves, describes what sources out in the Universe can
produce them, explains how they are detected and what the future of this
new era in astronomy might look like.
Sheila Rowan is a
professor in the School of Physics and Astronomy at University of
Glasgow. Her research focusses on gravitational wave detection on the
ground and in space. Her programme currently includes studies of ultra
sensitive mechanical systems; investigation of materials of ultra-low
mechanical loss and construction of mechanically-stable optical systems
for interferometric applications.
