Dark energy, exotic matter and properties of horizons in black hole physics and cosmology
K. A. Bronnikov, E. Elizalde, O. B. Zaslavskii
We summarize recent results on the properties of near-horizon metrics in different spherically symmetric space-times, including Kantowski-Sachs cosmological models whose evolution…
Horizons vs. singularities in spherically symmetric space-times
K. A. Bronnikov, E. Elizalde, S. D. Odintsov +1
We discuss different kinds of Killing horizons possible in static, spherically symmetric configurations and recently classified as "usual", "naked" and "truly naked" ones depending…
Cosmologies from nonlinear multidimensional gravity with acceleration and slowly varying G
K. A. Bronnikov, S. A. Kononogov, V. N. Melnikov +1
We consider multidimensional gravity with a Lagrangian containing the Ricci tensor squared and the Kretschmann invariant. In a Kaluza-Klein approach with a single compact extra spa…
Black holes can have curly hair
K. A. Bronnikov, O. B. Zaslavskii
We study equilibrium conditions between a static, spherically symmetric black hole and classical matter in terms of the radial pressure to density ratio p_r/ρ= w(u), where u is the…
