  • Speaker: Prof. Kin-Wang Ng (Academia Sinica)  /  Host: Prof. Pai-hsien Jennifer Hsu (NTHU)
    Place: R521, 5F, 2nd General Building, Nat'l Tsing Hua Univ.

We may live in an axiverse - an universe of a plenitude of axions, possibly populating each decade of mass scale down to the Hubble scale. Inflaton, dark matter, and dark energy may be axions. We discuss possible signatures of these axions in cosmic microwave background polarization and gravity-wave observations.
