  1. Statements of the interest in LCGT data analysis Ping Xi Shanghai United Center for Astrophysics (SUCA), Shanghai Normal University 2011-2-5

  2. Outline ► Interests in data analysisof LCGT ► Research experience ►Preparation for data analysis of LCGT 2011-2-5

  3. Prompted by Prof. Wei-Tou Ni, we are discussing possible participation in the LCGT project and what we will do for LCGT. 1. Interests in data analysisof LCGT Sources of Gravitational waves ♦ NS-NS ♦BH-BH ♦NS-BH Three stages for the evolution of a binary ♦inspiral ♦merger ♦ ringdown ‘Complete’ binary waveforms template ♦ Combining the results from analytical and numerical calculations, complete binary waveforms can be parametrized to produce analytical waveform templates. ♦ They can be used to estimate the efficiency of different searches in detecting signals from the binary coalescences. 2011-2-5
