Astronomers in the next year will be able to detect hundreds of black holes thanks to the brand new detectors of the Laser Interferometer Gravitational-Wave Observatory or LIGO, which is a new research by scientists from Cardiff University.
Their sole hope is that the research would aid scientists to have a look at data and pick out accurately which piece of the data displays gravitational ways and which are the ripples in the fabirc of spacetime that are generated by black holes during collision.
Learning more about black holes has always been one of the tedious things for researchers since ages, but the detectors by LIGO might be able to change that. This is due to the following reasons:
Scientists hunt for gravitational ways because black holes capture light and every other matter inside them and instead of illuminating light, they are not visible, which is why they are called black holes. Detectors by LIGO will find for these gravitational waves which depict where are the remnants of the black holes after their collision. The spinning of black holes is so fast that they wobble their orbits, and this wobbling generates the gravitational waves.
Dr. Mark Hannam, from the School of Physics and Astronomy at the university, says:“Our model aims to predict this behavior and help scientists find the signals in the detector data. Sometimes the orbits of these spinning black holes look completely tangled up, like a ball of string. But if you imagine whirling around with the black holes, then it all looks much clearer, and we can write down equations to describe what is happening.”
The detectors of LIGO is a project between the scientists at CalTech, MIT and other big universities around the world. While the search of gravitational waves has been going on as early as 2002, they didn’t find any and hence stopped the search at 2010. But now, researchers are attempting to bring back the search and the older detectors are being replaced by newer ones which have higher sensitivity than their predecessors.
