Giant laser observatory makes progress

By Maria Dasi Espuig

The Advanced Ligo instrument, a laser “ruler” built to measure the traces of gravitational waves, is progressing at amazing speed, scientists say. 770 more words


Gravitational Waves (Art Illustration)

Binary Spiral Wave
x = t*cos(s)
y = t*sin(s)
z = 2*cos(2*s+1*t)
with parameters s = (0,2*pi), t = (0,20)
Quadrupole Spiral Wave
x = v*cos(u) 18 more words

After two decades and more than half a billion dollars, LIGO, the world’s largest gravitational-wave observatory, is on the verge of a detection. Maybe. 3,520 more words

Why are complete compact-binary-coalescence waveforms so important for compact-object astrophysics?

The numerical relativity breakthrough in 2005 has provided waveforms of the gravitational wave signal emitted by a compact binary sources that describe the coalescence, the merger of the two compact objects and the ring-down of the newborn object. 273 more words
