Binary inspiral, gravitational radiation, and cosmology.
Observations of binary inspiral in a single interferometric gravitational wave detector can be cataloged according to signal-to-noise ratio ρ and chirp mass M. The distribution of events in a catalog composed of observations with ρ greater than a threshold ρ0 depends on the Hubble expansion, deceleration parameter, and cosmological constant, as well as the distribution of component masses in bi...
متن کاملObserving binary inspiral in gravitational radiation: One interferometer.
Close binary systems of compact objects with less than ten minutes remaining before coalescence are readily identifiable sources of gravitational radiation for the United States Laser Interferometer Gravitational-wave Observatory (LIGO) and the French-Italian VIRGO gravitational-wave observatory. As a start toward assessing the full capabilities of the LIGO/VIRGO detector network, we investigat...
متن کاملBinary neutron star inspiral, LIGO, and cosmology
The most promising anticipated source for the United States Laser Interferometer Gravitational-wave Observatory (LIGO) or its French/Italian counterpart VIRGO is the radiation emitted during the final moments of inspiral before the coalescence of a neutron star neutron star (ns-ns) binary system. The instruments that will operate in the LIGO facility will evolve over time, and the often-discuss...
متن کاملRadiation-balanced simulations for binary inspiral
The late stage of the inspiral of two black holes may have important non-Newtonian effects that are unrelated to radiation reaction. To understand these effects we approximate a slowly inspiralling binary by a stationary solution to Einstein’s equations in which the holes orbit eternally. Radiation reaction is nullified by specifying a boundary condition at infinity containing equal amounts of ...
متن کاملGravitational radiation reaction and inspiral waveforms in the adiabatic limit.
We describe progress evolving an important limit of binaries in general relativity: stellar mass compact objects spiraling into much larger black holes. Such systems are of great observational interest. We have developed tools to compute for the first time the radiation from generic orbits. Using global conservation laws, we find the orbital evolution and waveforms for special cases. For generi...
