Scientists have tried to validate the presence of gravitational waves that has evaded them for long. However a new research has recommended that addition of one of the planned detectors in India, Japan and Australia will enhance the detection rate.
In a study, Bernard Schutz, a professor of the Albert Einstein Institute in Germany, has showed that an additional detector would increase the rate of detection of gravitational waves.
Gravitational Waves
It was predicted that the present network having four detectors can detect 40 neutron-star combined events per year by 2016, through detecting the gravitational waves. This study demonstrates that the network can detect 160 events per year hypothetically by executing optimal coherent data analysis, using the computer analysis.
There is a huge increase in the detection rate by positioning the present network. But, the use of any of the three added spots would modify this significantly. Adding three new detectors would allow the detection of approximately 370 events a year and may increase to 500 events following the operation after a few years.
These detectors will probably detect the short spurts of gravitational waves, which occur from the two black holes or two stars orbiting each other. The complete acceleration of these events brings an alteration in space time called gravitational wave, which scatters out like ripples.
It is very hard to detect the space-time distortion, which is caused through accelerating objects and reduce slowly in strength when the waves reach the Earth.
Schutz expects that regular detections of gravitational waves from black holes would bear an unambiguous signature and have great penetrating power.
Japan’s detector is receiving grants for an additional detector while there are plans for developing detectors in India and Australia. GEO600, a British-German detector, will commence examinations for gravitational waves, till the VIRGO and LIGO detectors become completely functional.
