Race to Detect Gravitational Waves Advances w/ NANOGrav Physics Frontiers Center

Mostly American, but also includes folks form UBC and McGill

The NANOGrav PFC will address a transformational challenge in astrophysics: the detection of low-frequency gravitational waves. Gravitational waves are elusive ripples in the fabric of space-time, which theories predict should arise from extremely energetic and large-scale cosmic events, such as orbiting pairs of massive black holes found at the centers of merging galaxies, phase transitions in the very early Universe, or as relics from cosmic inflation, the period just after the Big Bang when all of the Universe that we can see expanded rapidly from a minuscule volume in a tiny fraction of a second.
