Researchers develop Technology to Allow LIGO Detectors to observe Weaker Gravitational Waves

Researchers at the Laser Interferometer Gravitational-Wave Observatory (LIGO) have detected gravitational waves two times until now, but they are planning to explore deeper in the space. A team of researchers from the Massachusetts Institute of Technology (MIT) and Australian National University claimed it has invented a technology that may help the LIGO in the mission.

The technology will make LIGO more sensitive to gravitational waves, ripples in the fabric of space-time resulted by the most violent and energetic processes in the cosmos, as per the MIT and Australian National University researchers.

The researchers said that a new squeezed vacuum source could be introduced in the LIGO detector that may double the detector’s sensitivity. It will allow LIGO to detect even those gravitational waves that are weaker and are from a source distant in the universe.

The team wants that the Advanced LIGO detectors should be used to detect farthest gravitational waves, or those waves that are weakest, said Nergis Mavalvala, lead researcher of the team from the MIT. “This is limited by the quantum fluctuations of the laser light, which create a certain level of noise. If a gravitational wave is weaker than that level of noise, then we can't detect it”, Mavalvala continued. Now, there’s an impetus that can decrease that noise, the researcher added.
