[閒聊] 重力波的發現和[email protected]計劃

作者: frankc (我要積極!)   2016-02-13 16:02:15
這幾天的新聞一直報導證實重力波的存在,就心想是不是 [email protected] 的成果,
上去官網查了一下:
Exciting news: Gravitational Waves detected!
We want to share our excitement about the first-ever direct detection of
gravitational waves! The event happened right before the beginning of the
first observing run of the advanced LIGO detectors, on 14 September 2015. The
waves were generated as two black holes merged into a single black hole about
1.3 billion light years from Earth. In astronomy units this is 410 Mpc,
approximately 10% of the way across the visible Universe!
Just as exciting: this is also the first-ever observation of binary black
holes. In fact, since black holes are black, and emit no light or
electromagnetic radiation, this is the only way we can see them.
Did [email protected] play any role in this? No, it didn't. The signal in the
instrument lasted only about 1/4 of a second. It’s not a continuous-wave
signal like the type that [email protected] has been searching for. But since the
observing run ended in mid January, we have been preparing the data to start
a new low-frequency all-sky search for continuous gravitational waves. We are
now starting to run this on [email protected], so please sign up your computers
and disable their sleep mode! In the next months we will extend the frequency
range of the continuous waves all-sky searches, target interesting point
sources and we are also gearing up to perform broader surveys for binary
black hole mergers.
意思應該是發現的重力波和[email protected]計劃搜尋的目的不太相同,不過之後會開始
運算低頻訊號,所以還是準備好機器來參與吧 :D
