The Center for Gravitational Wave Astronomy (CGWA), a NASA University Research Center athe the University of Texas, will sponsor the third summer school program in Gravitational Wave Astronomy. This program will encompass two weeks of intensive courses in four different areas of Gravitational Wave Astronomy including astrowhysics of gravitational wave sources, modeling of gravitational wave sources, analysis of gravitational wave data, and gravitational wave detector instrumentation. The school is oriented to senior undergraduates and junior graduate students with the scope of providing them necessary background to begin research programs in Gravitational Wave Astronomy. The school will be held in South Padre Island (TX) June 5-16, 2006. The deadline for the application is March 15, 2006.
