LISA spin measurements could exclude scalar and vector ultralight bosons over roughly four orders of magnitude in mass, while post-merger follow-up searches offer a narrower, model-dependent window for detecting vector boson clouds.

abstract
We construct Super-Eddington Slim Disks models around both stellar and super-massive black holes by allowing the formation of a porous layer with a reduced effective opacity. We show that at high accretion rates, the inner part of the disks become radiation pressure dominated. However, unlike the standard scenario in which the disks become thick, super-Eddington disks remain slim. In addition, they accelerate a significant wind with a "thick disk" geometry. We show that above about 1.5 times the standard critical mass accretion rate (needed to release the Eddington luminosity), the net luminosity released is above Eddington. At above about 5 times the standard critical rate, the central BH accretes more than the Eddington accretion rate. Above about 20 m-dot_crit, the disk remains slim but the wind becomes spherical, and the present model breaks down.

Probing ultralight bosons with LISA observations of spinning black hole mergers and follow-up searches of merger remnants
LISA spin measurements could exclude scalar and vector ultralight bosons over roughly four orders of magnitude in mass, while post-merger follow-up searches offer a narrower, model-dependent window for detecting vector boson clouds.
