Joint LIGO and TAMA300 Search for Gravitational Waves from Inspiralling Neutron Star Binaries
LIGO Scientific Collaboration, TAMA Collaboration
We search for coincident gravitational wave signals from inspiralling neutron star binaries using LIGO and TAMA300 data taken during early 2003. Using a simple trigger exchange met…
Correspondence between Loop-inspired and Braneworld Cosmology
Edmund J. Copeland, James E. Lidsey, Shuntaro Mizuno
Braneworld scenarios are motivated by string/M-theory and can be characterized by the way in which they modify the conventional Friedmann equations of Einstein gravity. An alternat…
Effects of Lovelock terms on the final fate of gravitational collapse: analysis in dimensionally continued gravity
Masato Nozawa, Hideki Maeda
We find an exact solution in dimensionally continued gravity in arbitrary dimensions which describes the gravitational collapse of a null dust fluid. Considering the situation that…
Cosmological Co-evolution of Yang-Mills Fields and Perfect Fluids
John D. Barrow, Yoshida Jin, Kei-ichi Maeda
We study the co-evolution of Yang-Mills fields and perfect fluids in Bianchi type I universes. We investigate numerically the evolution of the universe and the Yang-Mills fields du…
Close-limit analysis for head-on collision of two black holes in higher dimensions: Brill-Lindquist initial data
Hirotaka Yoshino, Tetsuya Shiromizu, Masaru Shibata
Motivated by the TeV-scale gravity scenarios, we study gravitational radiation in the head-on collision of two black holes in higher dimensional spacetimes using a close-limit appr…
Upper limits from the LIGO and TAMA detectors on the rate of gravitational-wave bursts
LIGO Scientific Collaboration, TAMA Collaboration
We report on the first joint search for gravitational waves by the TAMA and LIGO collaborations. We looked for millisecond-duration unmodelled gravitational-wave bursts in 473 hr o…
