LIGO. Laser Inferometer Gravity Wave Observatory. In future; may have them in multiple places on earth; Nothing stops GW; pass thru earth. Joe Weber designed & built first GWD in 1964. Vladimer Breginski lives in Moscow; led this group out of theoretical and into experimental study of gravity waves. Made the first gravity wave detector in 1980

The current proposed setup for the Laser Interferometric Gravitational Wave Observatory (LIGO) consists of a Michelson interferometer with Fabry-Perot cavities in each arm as well as a power recycling mirror between the input beam and the beam splitter and, in an advanced configuration, a …

Finally, of course, LIGO may register this background, and it is important that this signal be distinguished from noise. Quantization: The spectrum of the gravity wave background is computed by treating the waves as excitations of a field in some background curved spacetime and quantizing that field.

Many extensions are possible by more closely inspecting the data for this single gravity wave event. The LIGO-VIRGO collaboration offers data for many other published events and raw data for inventive searches. This exercise can be a jumping off point for student projects or further exercises which explore other data and could lead to an actual ...
The Effect of Transverse Shifts on the LIGO interferometer
The Laser Interferometer Gravitational-Wave Observatory (LIGO) is an ongoing project to measure the gravitational radiation predicted by general relativity. According to Albert Einstein’s theory of general relativity, gravity can be thought of as a curvature of space-time. Einstein’s theory predicts that when massive stellar objects are ...

(P3, C1&C2) Each Advanced LIGO experiment consists of “a modified Michelson interferometer that measures gravitational-wave strain as a difference in length of its orthogonal arms”. Using the diagram in Figure 3, explain this in simple terms.

Since the position of the center of the HR surface relative to the test mass center of gravity varies with the flexure, any noise in the ring heater power that can vary the flexure will create displacement noise. The details of this analysis are found in LIGO document T060224-00-D. ... Laser Interferometer Gravitational Wave Observatory ...

LIGO had not yet started their formal observing run, and with only two gravity wave detectors, one in Hanford, Washington, and one in Livingston, Louisiana, they could not pinpoint where in the sky, amongst billions and billions of galaxies, the source of this disturbance had occurred.

LIGO uses laser interferometers to detect the gravitational wave by measuring the interference of two laser beans whose length is changed when the gravitational wave passes by. LIGO has two observatory sites (H and L) in the United States with a total of three laser interferometers (H1, H2 and L1).
