WASHINGTON, February 12. / Corr. Tass Shitov /. Gravitational waves, the detection of which has now become a full-fledged scientific sensation, were originally identified and analyzed the algorithm of Russian scientist Sergey Klimenko. He now works at Florida University in the US and is involved in the project LIGO (Laser Interferometer Gravitational-wave Observatory), which officially belongs to celebrate the opening.
“For a change” …
As he told the Tass Klimenko, who arrived in Washington for the presentation of the results of the overall work on this project, he came in 1997 to try his hand in the new case. A graduate of Novosibirsk State University, he previously worked at the Russian Institute of Nuclear Physics, then in the American National Laboratory behalf of Enrico Fermi, he said, “all my life doing particle detectors,” but the search for the relationship had no gravitational waves. “At that time, the experiment (LIGO) was just beginning, the detectors just been built, and it was possible to sit, think – shared memories of a scientist -. Again, for a change decided to do data processing”
The fruit of reflection became algorithm. – sophisticated computer program that helps to isolate the desired information in the stream of extraneous noise. “The gist of it is that it looks at the data, finds a signal, assesses whether it is authentic, and the parameters of the signal reports and its conclusions,” – said the expert
“The main thing the program does not write, the main thing -. To come up – he said -. I invented it and developed together with my colleague from the University of Florida professor of genes Mitselmaherom and in 2004 it started to use “in the LIGO
it is still on the old detectors, which were insufficient.. sensitivity. In 2010-15 they upgraded. The total cost of the project at the same time has increased, according to the data from public sources, to $ 620 million. At the same time improved algorithm Klimenko.
Cherished Day
Date September 14, 2015 Now go down in history of science . According to the announcement of the National Science Foundation, the funding for the project work that day at 5:51 am US time East Coast while two observatories of the LIGO – in Louisiana and Washington – has been received, which eventually became the proof of the existence of gravitational waves. The fact that he was adopted and properly understood -. Klimenko merit and his offspring
The scientist himself was at that time at home in Florida. Around 6:30 he began to check e-mail box, where there was a notice on its program that something interesting happened. “I began to understand what it is, and very quickly realized that it was a phenomenal signal – the same thing that we’ve been looking for,” – said the expert
In fact, according to him, the incident even surpassed. expectations. “It was supposed to be two neutron stars, – said Klimenko -. But it turned out that the two” black hole
Here it should be noted that, as mentioned in the presentation, the discovery of such “binary” black holes “in itself was an important scientific discovery. With the help of gravitational waves, this phenomenon was observed and analyzed for the first time in history.
three minutes
Assessing the situation, Klimenko immediately warned about happened colleagues who worked on the detector in this case it was particularly important since the device is at the moment not even in normal operating mode, and in the trial, actually. – . in a state of adjustment that is, the system could be modified, after which the signal thorough check would be impossible
and it clearly highlights another advantage Klimenko program -.. performance Already at that time she was able to find and estimate the desired signal, including the criterion of reliability, for a total of three minutes. “This is one of the few algorithms that can do it” – now says the author. His own note on “unique event” – with an explanation of such an assessment – went to the objects already in the region of 7:15 am
Other -. Is history
The rest, including a thorough examination of the whole and whole – is history. The correctness of the initial assessment is confirmed and enshrined in the publication, which is now publicly available. For our learned it – is the main result
“The article in fact a landmark, -. Said Klimenko -. She summed up the research, which lasted a hundred years, it solved one of the most difficult problems in physics and in this paper there.. two references to my work. Of course, I’m not the only one working, I have co-authors. But it’s nice that in such an important discovery, and there is my contribution. “
