9th Seminar on Gravitational Waves and Numerical Relativity
Information
- Date: Jan. 10 (Fri.), 2020, 2 pm - 5 pm
- Venue: Room B106, Science Building D, Ewha Womans University
- Title: Gravitational Wave Data Analysis
- Speaker: Hyung Won Lee (Inje University)
- Abstract: After the first detection of gravitational wave on September 14, 2015 by LIGO and Virgo collaboration, there has been, and still are, a lot of interest on gravitational waves. The fact that gravitational waves not only open a new window for observing the Universe but also the technical breakthroughs we had to make to detect the weakest signal in nature is what makes gravitational wave so interesting. The gravitational wave is very weak by nature, and it is enormously difficult to detect. Actually it took more than 20 years of development since the conceptual design to make the first observation. In this talk I want to introduce basics of gravitational wave detection principle using large optical interferometer and how one can extract relevant signal from noisy data for general audience. This talk is based on the two LIGO documents for data extraction (arXiv:1908.11170) and parameter estimation (PRD91042003).
