The Black Hole Spin Puzzle
12:00 pm – 1:00 pm EST/GMT-5
The way in which stars form nearly always leads them to spin. It is widely believed that all black holes form out of these stars, and hence should also be spinning. However, the incredible gravitational wave measurements of the last five years suggest that there could be many black holes that do not spin. How do you create such black holes? Where do they come from? Are they qualitatively different aside from their low spins? These and related questions make up the black hole spin puzzle. I will explain how the birth of black holes in the early universe may provide a resolution to the black hole spin puzzle. My collaborators and I recently won a Buchalter Cosmology Prize for this work.
