New Research Project Of China In The Field Of Gravitational Waves
China's domestic gravitational wave research project started by Sun Yat-sen University of China in July 2015 is waiting from a long time for government’s approval.
The triumph of directly identifying the gravitational wave has gone to make it possible for all the human beings to look deepest into space when Us based Laser Interferometer Gravitational-Wave Observatory (LIGO) finally with success sensed the ripples in the fabric of space-time causing by the merger of two black holes 1.3 billion years ago.
This research is due to the full efforts of more than 1,000 scientists from different universities around all the United States same as in 14 different nations. Among all of them-they was a team of five different Chinese scientists from one of the great Tsinghua University who have worked on gravitational wave data analyst.
"It is really a great thrilling research, and their team dealing with data," said Prof. Cao Junwei, senior head of LIGO Scientific Collaboration research group at Tsinghua University. As it is the only member from mainland China in LIGO scientific collaboration (LSC), Cao's group focusing on same gravitational wave data analysis using their latest computing technologies to help "purify" the received signals.
In the search for the original gravitational wave signals, scientists had to dump out unnecessary vibrations causing by noise sources, which is not so easier than identifying a Morse code tapped on a beer glass at a grand celebration party bustling with a crowd.
The team applied a procedure of "machine learning" to the analysis, which is started in the field of their artificial intelligence. It is comparing the signs in the gravitational wave channel with the different channels, and a couple of signals helped them to rule out unnecessary signals. That convert the signal identification and detection into the same problems of data analysis and processing, which is going to be a tough point of the Tsinghua group, Cao said Xinhua.
"In the time of long period, LIGO was not so sensitive enough to see a passed gravitational wave. What we have observed and started are all crowd. But it was not a time waste. The past experiences helped LIGO to upgrade and improve the sensitivity," Cao said.
He noticed that the observation of a gravitational wave filled by the prediction of Einstein's normal theory of relativity and opened the newest window on exploring of space. It will also be a cutting-edge improvement of optics, computer science, engineering and many more different important subjects.
The US-based Laser Interferometer Gravitational-wave Observatory (LIGO) declared that ground-breaking discovery of gravitational waves on Thursday, which completed the imagination of Albert Einstein's normal theory of relativity 100 years ago.
The latest discovery has encouraged further research into gravitational waves all over the world, with China accelerating its domestic research, Xinhua news organization Li Miao, Head of the College of Astronomy and Space Science of a university in China, as telling.
As per Li, Tianqin has already made progress on some of the key technologies and these all will be carried out in four different stages over the coming 15 to 20 years, it includes the last step of starting the three high-orbit satellites to identify the gravitational waves.
The university is planning to build a 5,000-square-metre observatory and a very newly lab. It will cover more than 10,000 square meters in Zhuhai city on Fenghuang Mountain in Guangdong area.
The Sun Yat-sen University can cooperate with different institutions in the China same as around the world to carry out its project.
