COURSE TOPICS:
Grid applications in gravitational wave data analysis (PART II): A UTB graduate student, Santiago Pena, who is currently under M. Campanelli supervision, has been working on gravitational wave data analysis of signals from extreme mass-ratio inspirals, which are important potential sources for the future space-based detector LISA (Laser Interferometer Space Antenna), a NASA-ESA mission scheduled for launch around 2011. LISA will detect GWs from a variety of sources. One of the important sources will be inspirals of compact objects (white dwarfs, neutron stars, or stellar-mass black holes) into Super-massive black holes residing in the cores of galaxies. The parameter space for such capture events is enormous. Each inspiral is characterized by 17 unknown parameters. Consequently, we will need a huge bank of templates (perhaps ~10^50!) to dig GW signal out of the noise of the LISA detector. Since parameter space is so huge one needs to use Monte-Carlo methods, based on random sampling. This is most efficiently done using some VDT software, like Condor, allowing to sample many points in parameter space simultaneously.
