Kerroll black holes

Alfredo P\'erez, Daniel Grumiller, Florian Ecker, Lucas H\"orl, Matt\'eo Leturcq--Daligaux

Carroll gravity admits rotating black hole solutions, one intrinsically Carrollian with no Lorentzian analog and another as a Kerr analog from an odd-power expansion in the speed of light.

Claims

C1strongest claim

We construct rotating black holes in Carroll gravity... This solution is intrinsically Carrollian and has no Lorentzian analog... We show that this theory admits a Carroll analog of the Kerr black hole as a solution, which we refer to as the 'Kerroll black hole'.

C2weakest assumption

The assumption that the freedom in the Carroll-compatible connection can be used to encode a rotational charge without introducing inconsistencies or reducing to a Lorentzian solution (first approach), and that the odd-power expansion in the speed of light yields a consistent extension containing magnetic Carroll gravity as a subsector (second approach).

C3one line summary

Rotating black holes are constructed in Carroll gravity via connection freedom and an odd-power GR expansion, yielding an intrinsically Carrollian rotating solution and the Kerroll black hole analog.
