A radiometer for stochastic gravitational waves
The LIGO Scientific Collaboration recently reported a new upper limit on an isotropic stochastic background of gravitational waves obtained based on the data from the 3rd LIGO science Run (S3). Now I present a new method for obtaining directional upper limits that the LIGO Scientific Collaboration intends to use for future LIGO science runs and that essentially implements a gravitational wave r...
متن کاملStochastic backgrounds of gravitational waves
We review the motivations for the search of stochastic backgrounds of gravitational waves and we compare the experimental sensitivities that can be reached in the near future with the existing bounds and with the theoretical predictions.
متن کاملUpper limits on a stochastic background of gravitational waves.
The Laser Interferometer Gravitational-Wave Observatory has performed a third science run with much improved sensitivities of all three interferometers. We present an analysis of approximately 200 hours of data acquired during this run, used to search for a stochastic background of gravitational radiation. We place upper bounds on the energy density stored as gravitational radiation for three d...
متن کاملDetecting a stochastic background of scalar gravitational waves with LIGO
With the “bouncing photon” treatment, the gauge invariance of the response function of interferometers to scalar gravitational waves (SGWs) has been recently demonstrated in its full frequency dependence in three different gauges well known in literature, while in previous works such invariance was only proved in the low frequencies approximation. After a review of scalar tensor theories of gra...
متن کاملLimits on the Stochastic Gravitational Wave Background from the North American Nanohertz Observatory for Gravitational Waves
Here we present an analysis of high-precision pulsar timing data taken as part of the North American Nanohertz Observatory for Gravitational waves (NANOGrav) project. We have observed 17 pulsars for a span of roughly five years using the Green Bank and Arecibo radio telescopes. We analyze these data using standard pulsar timing models, with the addition of time-variable dispersion measure and f...
