The Laser Interferometer Gravitational-Wave Observatory (LIGO) is a large-scale physics experiment and observatory designed to detect cosmic gravitational waves and to develop gravitational-wave observations as an astronomical tool. [1]
It was published in 2020 that a gamma-ray burst was detected ~0.5 seconds after the LIGO trigger, lasting 6 seconds and bearing similarities to GRB170817 (such as weakness [most power in sub-100 keV, or soft X-rays) bands], elevated energetic photon background levels [signal exceeding background by less than a factor of 2], and similar ...
Livingston Parish is home of one of two installations for the gravitational wave observatory (LIGO) which is a facility dedicated to the detection of cosmic gravitational waves for scientific research. [16] As of January 2015, Livingston Parish was Louisiana's fastest-growing parish. [17]
LSC members have access to the US-based Advanced LIGO detectors in Hanford, Washington and in Livingston, Louisiana, as well as the GEO 600 detector in Sarstedt, Germany. Under an agreement with the European Gravitational Observatory (EGO), LSC members also have access to data from the Virgo detector in Pisa , Italy.
LIGO measurement of the gravitational waves at the Hanford (left) and Livingston (right) detectors, compared to the theoretical predicted values. On 11 February 2016, the LIGO collaboration announced the first observation of gravitational waves , from a signal detected at 09:50:45 GMT on 14 September 2015 [ 39 ] of two black holes with masses ...
Livingston is the parish seat of Livingston Parish, Louisiana, United States. [2] The population was 1,769 at the 2010 census . Livingston hosts one of the two LIGO gravitational wave detector sites, the other one being located in Hanford, Washington .
The first direct observation of gravitational waves was made on 14 September 2015 and was announced by the LIGO and Virgo collaborations on 11 February 2016. [3] [4] [5] Previously, gravitational waves had been inferred only indirectly, via their effect on the timing of pulsars in binary star systems.
English: First observation of gravitational waves by LIGO (signal GW150914). Shows the gravitational wave signals received by the LIGO instruments at Hanford, Washington (left) and Livingston, Louisiana (right) and comparisons of these signals to the signals expected due to a black hole merger event.
