Talk Title: 
"Did LIGO Detect Dark Matter?"
Event description: 
I will discuss the possibility that the black-hole binary detected by LIGO may be a signature of primordial black hole dark matter.  There remains a small window where primordial black hole dark matter is not yet ruled out, which happens to overlap with the LIGO detection. If two BHs in a galactic halo pass sufficiently close, they radiate enough energy in gravitational waves to become gravitationally bound. Curiously, the expected merger rate from these objects overlaps with that predicted by LIGO.
