报告题目:The promise and the prospects of gravitational wave astronomy
报 告 人:Prof. David Blair
( School of Physics, University of Western Australia, Australia)

报告时间: 2013年10月28日(周一) 9:30-10:30
报告地点:力学所5号楼会议中心207会议室

报告内容:Gravitational waves offer astronomers a means of probing extreme states of matter beyond the reach of electromagnetic astronomy, from the earliest moments of the big bang to the vibrating event horizons of black holes. Through 40 years of effort, the flux sensitivity of gravitational wave detectors has been improved by a factor of 1016. Gravitational waves have not yet been detected but the latest generation of detectors now under construction promise certain detections of known sources.
The development of gravitational wave detectors is technologically very significant. “Of all the large scientific projects out there, this one is pushing the greatest number of technologies the hardest.”
The world requires a southern hemisphere detector to obtain accurate direction information on sources that can allow X-ray telescopes and optical telescopes to follow up the signal sources. An international detector in Australia would be a pivotal element in a world array of detectors, enabling all sky imaging of sources with adequate angular resolution.

报告人简历:Prof. David Blair was educated in Australia and the UK. He worked on large scale cryogenic resonant mass gravitational wave detectors first in the USA and then in Australia. He used a large bar of superconducting niobium to build the gravitational wave detector NIOBE, which operated in a world wide network from 1993-2000. He now works in the area of laser interferometer gravitational wave detectors, spin-off technologies and Einsteinian physics education. He leads the Australian International Gravitational Research Centre at Gingin, Western Australia, site of the planned southern hemisphere gravitational wave detector.
