Description: Author(s): B. P. Abbott et al. (LIGO Scientific Collaboration and Virgo Collaboration) We present an archival search for transient gravitational-wave bursts in coincidence with 27 single-pulse triggers from Green Bank Telescope pulsar surveys, using the LIGO, Virgo, and GEO interferometer network. We also discuss a check for gravitational-wave signals in coincidence with Parkes fast r… [Phys. Rev. D 93, 122008] Published Mon Jun 20, 2016

Description: Author(s): B. P. Abbott et al. (LIGO Scientific Collaboration and Virgo Collaboration) LIGO has detected a second burst of gravitational waves from merging black holes, suggesting that such detections will soon become routine and part of a new kind of astronomy.

Description: Author(s): B. P. Abbott et al. (LIGO Scientific Collaboration and Virgo Collaboration) The recent announcement by LIGO of the detection of the gravitational-wave signal GW150914 has ignited tremendous interest. The two manuscripts highlighted here detail the impressive analysis performed by LIGO to identify a specific black hole binary merger as the source of GW150914. The papers describe two independent methods of analysis: the matching of the signal to numerical-relativity-generated templates and unmodeled burst analyses. The two papers together provide detailed and virtually incontrovertible evidence, by the standards of experimental physics, of the detection of gravitational waves generated by a merger of a black hole binary system consisting initially of black holes of approximately 36 and 29 solar masses.

Description: A stochastic background of gravitational waves is expected to arise from a superposition of a large number of unresolved gravitational-wave sources of astrophysical and cosmological origin. It should carry unique signatures from the earliest epochs in the evolution of the Universe, inaccessible to standard astrophysical observations. Direct measurements of the amplitude of this background are therefore of fundamental importance for understanding the evolution of the Universe when it was younger than one minute. Here we report limits on the amplitude of the stochastic gravitational-wave background using the data from a two-year science run of the Laser Interferometer Gravitational-wave Observatory (LIGO). Our result constrains the energy density of the stochastic gravitational-wave background normalized by the critical energy density of the Universe, in the frequency band around 100 Hz, to be 〈6.9 x 10(-6) at 95% confidence. The data rule out models of early Universe evolution with relatively large equation-of-state parameter, as well as cosmic (super)string models with relatively small string tension that are favoured in some string theory models. This search for the stochastic background improves on the indirect limits from Big Bang nucleosynthesis and cosmic microwave background at 100 Hz.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉LIGO
