On searches for gravitational waves from mini-creation events by laser interferometric detectors

چکیده
As an alternative view to the standard big bang cosmology, the quasi-steady-state cosmology argues that the Universe was not created in a single great explosion: it did not have a beginning, nor will it ever come to an end. The creation of new matter in the Universe is a regular feature occurring through finite explosive events. Each creation event is called a mini-bang, or a minicreation event. Gravitational waves are expected to be generated as a result of any anisotropy present in this process of creation. A mini-creation event that ejects matter in two oppositely directed jets is thus a source of gravitational waves, which can in principle be detected by laser interferometric detectors. In the present work we consider the gravitational waveforms propagated by linear jets and then estimate the response of laser interferometric detectors such as LIGO and LISA.

Laser interferometric detectors of gravitational waves
A laser interferometric detector of gravitational waves is studied and a complete solution (to first order in the metric perturbation) of the coupled Einstein-Maxwell equations with appropriate boundary conditions for the light beams is determined. The phase shift, the light deflection and the rotation of the polarization axis induced by gravitational waves are computed. The results are compare...
متن کاملA common misconception about LIGO detectors of gravitational waves
A common misconception about laser interferometric detectors of gravitational waves purports that, because the wavelength of laser light and the length of an interferometer’s arm are both stretched by a gravitational wave, no effect should be visible, invoking an analogy with cosmological redshift in an expanding universe. The issue is clarified with the help of a direct calculation.
متن کاملThe status of laser interferometer gravitational-wave detectors
There has been a rapid advance in the sensitivity of broadband searches for gravitational waves, using an international network of kilometer-scale laser interferometers. The LIGO detectors in North America, the GEO600 detector in Germany and the TAMA300 detector in Japan have conducted searches for gravitational waves covering a frequency range from below 100 Hz up to many kHz. These detectors ...
متن کاملSearching for gravitational waves with LIGO
The Laser Interferometer Gravitational-wave Observatory (LIGO) detectors have reached their design sensitivity, and searches for gravitational waves are ongoing. We highlight current attempts to detect various classes of signals. These include unmodelled sub-second bursts of gravitational radiation, such as from core-collapse supernovae and gamma-ray burst engines. Gravitational waves from isol...

The detection of gravitational waves from astrophysical sources of gravitational waves is a realistic goal for the current generation of interferometric gravitational-wave detectors. Short duration bursts of gravitational waves from core-collapse supernovae or mergers of binary black holes may bring a wealth of astronomical and astrophysical information. The weakness of the waves and the rarity...
