Nonthermal nature of extremal Kerr black holes
Liberati, Rothman and Sonego have recently showed that objects collapsing into extremal Reissner-Nordström black holes do not behave as thermal objects at any time in their history. In particular, a temperature, and hence thermodynamic entropy, are undefined for them. I demonstrate that the analysis goes through essentially unchanged for bodies collapsing into extremal Kerr black holes. PACS: 0...

where is the problem? health scientists are constantly trying to support people by diagnosing, managing the diseases, and improving health in all possible dimensions. attention has been drawn to all aspects of health including biological, psychological, social and spiritual. the problem may lay in behavior, clinical issues, organ cites, genome and epigenome. thus it falls on us, the medical soc...
متن کاملConservative corrections to the innermost stable circular orbit (ISCO) of a Kerr black hole: A new gauge-invariant post-Newtonian ISCO condition, and the ISCO shift due to test-particle spin and the gravitational self-force
The innermost stable circular orbit (ISCO) delimits the transition from circular orbits to those that plunge into a black hole. In the test-mass limit, well-defined ISCO conditions exist for the Kerr and Schwarzschild spacetimes. In the finite-mass case, there are a large variety of ways to define an ISCO in a post-Newtonian (PN) context. Here I generalize the gauge-invariant ISCO condition of ...
متن کاملNear Extremal Kerr Entropy from AdS2 Quantum Gravity
We analyze the asymptotic symmetries of near extremal Kerr black holes in four dimensions using the AdS2/CFT1 correspondence. We find a Virasoro algebra with central charge cR = 12J that is independent from the Virasoro algebra (with the same central charge) that acts on the degenerate ground state. The energy of the excitations is computed as well, and we can use Cardy’s formula to determine t...
متن کاملwhere is the happy ending of shāhnāma?
the renowned proverb “shāhnāma axarash xoš ast” has implicit question which its answer may change our understanding of the nature and function of shāhnāma. the end of shāhnāma contains numerous tragic events in sassanid age. also it does not seem to be normal if the iranians have deemed the bitter adventure of the shahs and pahlavāns as a happy ending like what firdausi narrates at the end of h...
