Description
Last year, multiple pulsar timing array collaborations across the globe announced the first evidence of a stochastic background of nHz-frequency gravitational waves. A population of inspiraling supermassive black hole binaries can generate a stochastic background, but there may also be contributions from exotic cosmological sources that formed around the time of the Big Bang. In this talk, I will provide an overview of pulsar timing, present the analyses of the latest 15-year NANOGrav data, and discuss new-physics interpretations.
