Gravitational waves detected from second pair of colliding black holes
Gravitational waves second pair colliding black holes
2016/6/22
On Dec. 26, 2015 at 03:38:53 UTC, scientists observed gravitational waves -- ripples in the fabric of spacetime -- for the second time.
The gravitational waves were detected by both of the twinLaser ...
Pair creation of dilaton black holes
Theory of gravity time and space dimensions coupling a black hole magnetism
2014/12/23
We consider dilaton gravity theories in four spacetime dimensions parametrized by a constant a, which controls the dilaton coupling, and construct new exact solutions. We first generalize the C metric...
Non-extreme Calabi-Yau black holes
4 d black holes supergravity theory independent module and scalar function coupling matrix
2014/12/22
Non-extreme black hole solutions of four dimensional, N = 2 supergravity theories with Calabi-Yau prepotentials are presented, which generalize certain known double-extreme and extreme solutions. The ...
From wrapped M-branes to Calabi-Yau black holes and strings
Time and space time and space movement equation the black hole black string
2014/12/20
We study a class of D = 11 BPS spacetimes that describe M-branes wrapping supersymmetric 2 and 4-cycles of Calabi-Yau 3-folds. We analyze the geometrical significance of the supersymmetry constraints ...
Stresses and strains in the first law for Kaluza-Klein black holes
Both black hole kaluza-klein thermodynamics first law static black holes
2014/12/20
We consider how variations in the moduli of the compactification manifold contribute `pdV' type work terms to the first law for Kaluza-Klein black holes. We give a new proof for the S1 case, based on ...
The first law for boosted Kaluza-Klein black holes
Both black hole kaluza-klein thermodynamics time and space
2014/12/20
We study the thermodynamics of Kaluza-Klein black holes with momentum along the compact dimension, but vanishing angular momentum. These black holes are stationary, but non-rotating. We derive the fir...
Enthalpy and the mechanics of AdS black holes
Geometric Smarr formula of static black hole the first law the cosmological constant
2014/12/19
We present geometric derivations of the Smarr formula for static AdS black holes and an expanded first law that includes variations in the cosmological constant. These two results are further related ...
A Nonsingular Brans Wormhole: An Analogue to Naked Black Holes
Nonsingular Brans Wormhole Black Holes Analogue
2011/10/10
Abstract: In a recent paper, we showed the Jordan frame vacuum Brans Class I solution provided a wormhole analogue to Horowitz-Ross naked black hole in the wormhole range -3/2<{\omega}<-4/3. Thereafte...

Abstract: This is a concise review, addressed to undergraduate students, of S. Chandrasekhar's oeuvre in astrophysics, ranging from his early studies on white dwarfs using relativistic quantum statist...
Hidden Symmetries for Ellipsoid-Solitonic Deformations of Kerr-Sen Black Holes and Quantum Anomalies
Hidden symmetries in general relativity gravitational anomalies nonholonomic deformations
2011/7/25
Abstract: We prove the existence of hidden symmetries in the general relativity theory defined by exact solutions with generic off-diagonal metrics, nonholonomic (non-integrable) constraints, and defo...

Superkicks ultrarelativistic encounters spinning black holes
2010/12/20
We study ultrarelativistic encounters of two spinning, equal-mass black holes through simulations in full numerical relativity. Two initial data sequences are studied in detail: one that leads to scat...
