The eXtreme Digital Request Allocation Committee (XRAC) recommended an extension of our NSF Grant PHY-090003 (High energy grazing collisions of black holes, PI: Ulrich Sperhake, Co-Is: Emanuele Berti, Vitor Cardoso, Frans Pretorius). This grant will provide us with 2,000,000 core hours from XSEDE (formerly known as TeraGrid) to study black hole collisions.
