Superradiance in String Theory

Viraf M. Mehta, Mehmet Demirtas, Cody Long +3

We perform an extensive analysis of the statistics of axion masses and interactions in compactifications of type IIB string theory, and we show that black hole superradiance exclud…

Superradiance Exclusions in the Landscape of Type IIB String Theory

Viraf M. Mehta, Mehmet Demirtas, Cody Long +3

We obtain constraints from black hole superradiance in an ensemble of compactifications of type IIB string theory. The constraints require knowing only the axion masses and self-in…

Ultralight Bosonic Field Mass Bounds from Astrophysical Black Hole Spin

Matthew J. Stott

Black Hole measurements have grown significantly in the new age of gravitation wave astronomy from LIGO observations of binary black hole mergers. As yet unobserved massive ultrali…

The Spectrum of the Axion Dark Sector, Cosmological Observable and Black Hole Superradiance Constraints

Matthew J. Stott

Consistent frameworks of quantum gravity often predict the existence of large numbers of ultralight pseudoscalar degrees of freedom, forming the phenomenological landscape of the S…

Black Hole Spin Constraints on the Mass Spectrum and Number of Axion-like Fields

Matthew J. Stott, David J. E. Marsh

Astrophysical observations of spinning BHs, which span , can be used to exclude the existence of certain massive bosons v…

The Spectrum of the Axion Dark Sector

Matthew J. Stott, David J. E. Marsh, Chakrit Pongkitivanichkul +2

Axions arise in many theoretical extensions of the Standard Model of particle physics, in particular the "string axiverse". If the axion masses, , and (effective) decay consta…
