Early growth of massive black holes in dynamical dark energy models with negative cosmological constant
N. Menci, M. Castellano, P. Mukherjee +4
Recent results from combined cosmological probes indicate that the Dark Energy component of the Universe could be dynamical. The simplest explanation envisages the presence of a qu…

Supersymmetric Index for Half BPS Black Holes in N=2 Supergravity with Higher Curvature Corrections
Subramanya Hegde, Ashoke Sen, P Shanmugapriya +1
We compute the supersymmetric index of half BPS black holes in N=2 supergravity with higher curvature corrections and show that the result agrees with the degeneracy of supersymmet…

Supersymmetric Index for Small Black Holes
Chandramouli Chowdhury, Ashoke Sen, P. Shanmugapriya +1
Supersymmetric elementary string states in the compactified heterotic string theory are described by small black holes that have zero area event horizon. In this paper we compute t…
