Non-Expanding horizons: Multipoles and the Symmetry Group
Abhay Ashtekar, Neev Khera, Maciej Kolanowski +1
It is well-known that blackhole and cosmological horizons in equilibrium situations are well-modeled by non-expanding horizons (NEHs). In the first part of the paper we introduce m…

Towards the black hole uniqueness: transverse deformations of the extremal Reissner-Nordström-(A)dS horizon
Maciej Kolanowski
We study all transverse deformations of the extremal Reissner-Nordström-(A)dS horizon in the Einstein-Maxwell theory. No symmetry assumptions are needed. It is shown that for the g…

Hamiltonian charges in the asymptotically de Sitter spacetimes
Maciej Kolanowski, Jerzy Lewandowski
We generalize a notion of 'conserved' charges given by Wald and Zoupas to the asymptotically de Sitter spacetimes. Surprisingly, our construction is less ambiguous than the one enc…
