A proposed site for measuring these events in India would join existing ones in (*) Hanford, Washington and Livingston, Louisiana.
When analyzing these events, one typically applies a 35 to 350 hertz bandpass filter to suppress shot noise and power grid harmonics. These events are analyzed using both a generic transient search and a binary coalescence search. They are detected using a 1064Â­nanometer Nd:YAG laser and 40Â­kilogram blocks of fused silica. A proposed site for measuring these events in India would join existing ones in (*) Hanford, Washington and Livingston, Louisiana. A recent one of these events exhibited a frequency sweep up to 250 hertz that was consistent with the inspiralÂ­mergerÂ­ringdown sequence of its binary black hole source. That event resulted in the radiation of three solar masses of energy. For 10 points, name these relativistic warpings of spacetime, which were first recorded by LIGO in September 2015.
