Gravitational wave detector prepares to peer into bizarre stars

Prepare for a big wave - a wave of gravitational waves. A mass of predictions from the latest meeting of the American Physical Society in Washington DC is shedding light on what's next for the massive LIGO collaboration.
With two sets of colliding black holes in its net and another possible pair in its second run, LIGO, the world's first successful gravitational wave detector is finally ready to see the unexpected.
LIGO's second run began on 30 November 2016. On 28 January, the team announced that it had seen two event candidates so far, which matches the expected rate of about one per month.

Advanced Ligo gravitational wave hunt is green lit

One of the great physics experiments of our age looks ready to begin its quest.
Scientists have held a dedication ceremony to inaugurate the Advanced Ligo facilities in the US.
This pair of widely separated laboratories will be hunting for gravitational waves.

Newly dedicated observatory to search for gravitational waves

Seeking to expand how we observe and understand the universe where we live, the National Science Foundation today helped dedicate the Advanced Laser Gravitational Wave Observatories (Advanced LIGO) at the LIGO Hanford facility in Richland, Wash.

Echoes of the birth of the universe
Results of cosmic analysis set new limits on gravitational waves that could have come from the Big Bang, and begin to constrain current theories about universe formation

An investigation by the LIGO (Laser Interferometer Gravitational-Wave Observatory) Scientific Collaboration, designed and operated by Caltech and MIT, and the Virgo Collaboration, has significantly advanced our understanding of the early evolution of the universe.

Gravitational Wave Observatory listens for echoes of universe's birth
An investigation by a major scientific group headed by a University of Florida professor has advanced understanding of the early evolution of the universe. An analysis of data from the Laser Interferometer Gravitational-Wave Observatory Scientific Collaboration, or LIGO, and the Virgo Collaboration has set the most stringent limits yet on the amount of gravitational waves that could have come from the Big Bang in the gravitational wave frequency band where LIGO can observe. In doing so, scientists have put new constraints on the details of how the universe looked in its earliest moments.

British-made technology will boost the search for elusive gravitational waves
UK scientists are helping us edge ever closer to finding the mysterious, theorised ripples in the fabric of spacetime (known as gravitational waves) with the production of 25 new assemblies for the LIGO facility - a network of detectors designed to search for these elusive waves.
Funded by the US National Science Foundation (NSF), LIGO also allows us to look inside the most violent events in the Universe and traces its exotic phenomena in great detail. By increasing the sensitivity of the LIGO detectors by a factor of ten, the upgrades will greatly increase our chances of finding gravitational waves and open a new observational window on the Universe to test our current theories and models.

LIGO observatory to offer tour, astronomy talk
New to the observatory is an Advanced LIGO Controls Prototype Quadruple Suspension, or in more simple terms, a roughly 1000 pound four-level steel pendulum. LIGO is located west of Richland on Highway 10.
There is no fee.
For more information call 372-8181 or e-mail outreach@ligo-wa.Caltech.edu.

Title: First LIGO search for gravitational wave bursts from cosmic (super)strings
Authors: LIGO Scientific Collaboration: B. Abbott, et al

We report on a matched-filter search for gravitational wave bursts from cosmic string cusps using LIGO data from the fourth science run (S4) which took place in February and March 2005. No gravitational waves were detected in 14.9 days of data from times when all three LIGO detectors were operating. We interpret the result in terms of a frequentist upper limit on the rate of gravitational wave bursts and use the limits on the rate to constrain the parameter space (string tension, reconnection probability, and loop sizes) of cosmic string models.
