The International community of Gravitational Wave scientists are a few steps closer to detect a new source of gravitational waves that has never been detected.

Distinguished Prof. Susan Scott, Dr Karl Wette and Dr Lilli Sun from CGA along with the LIGO Scientific Collaboration (LSC) and Virgo Collaboration are focusing their reasech on 'continuous gravitational waves' that are a steady constant stream or "hum" of gravitational waves that are caused by spinning of neutron stars. The researchers say continuous gravitational waves can be the result of single spinning neutron stars with a bulge or "mountain" only a few millimetres high. 

If successful, it would be the first detection of a gravitational wave event that didn't involve the collision of massive objects like black holes or neutron stars.
