Astronomy: February 2016 Archives

GW150914: First results from the search for binary black hole coalescence with Advanced LIGO, The LIGO Scientific Collaboration, the Virgo Collaboration

"In addition to possible gravitational-wave signals, the detector strain contains a stationary noise background that primarily arises from photon shot noise at high frequencies and seismic noise at low frequencies."

Gravitational Waves Detected

"For the first time, scientists have observed ripples in the fabric of spacetime called gravitational waves, arriving at Earth from a cataclysmic event in the distant universe. This confirms a major prediction of Albert Einstein's 1915 general theory of relativity and opens an unprecedented new window to the cosmos."

Hanford's scientists finally spill gravitational-wave secrets - but they still can't tell all, Geekwire

"Meanwhile, there are already rumors that LIGO registered more readings that aren't yet ready to be reported."

Keith's note: Taxpayers have seen more than $600 million spent on LIGO yet NSF purposefully shut off their live webcast from their LIGO event well before it was completed. Why would taxpayers want to hear what the scientists have to say?
