[闲聊] 重力波的发现和[email protected]计划

楼主: frankc (我要积极!)   2016-02-13 16:02:15
这几天的新闻一直报导证实重力波的存在,就心想是不是 [email protected] 的成果,
上去官网查了一下:
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.
意思应该是发现的重力波和[email protected]计划搜寻的目的不太相同,不过之后会开始
运算低频讯号,所以还是准备好机器来参与吧 :D
