Black holes: fundamentals and controversies
(Asociación Argentina de Astronomía, 2016)
Los agujeros negros son objetos totalmente colapsados en su campo gravitacional. Han sido estudia- dos teóricamente durante mas de cuarenta años utilizando la teoría de la relatividad general. Más recientemente, se los ha ...
Dynamics of an acoustic black hole as an open quantum system
(American Physical Society, 2013-04-11)
We study the process of decoherence induced by the presence of an environment in acoustic black holes, using the open quantum system approach, thus extending previous work. We focus on the ion trap model but the formalism ...
An OpenFOAM Application for Solving the Black Oil Problem
(Pleiades, 2021-09)
An OpenFOAM application to address black oil problems using the finite volume technique is presented, along with the first results of the new solver. The black oil formulation is well known in petroleum reservoir engineering ...
Chemical potential driven phase transition of black holes in anti-de Sitter space
(American Physical Society, 2015-11)
Einstein-Maxwell theory conformally coupled to a scalar field in D dimensions may exhibit a phase transition at low temperature whose end point is an asymptotically anti-de Sitter black hole with a scalar field profile ...
The infalling photon, the infalling particle, and the observer at rest near the horizon of a black hole
(IOP Publishing, 2020-11)
When a massive test particle or a photon fall radially into a black hole, their energy, as measured by a static observer located very close to the horizon, diverges. In introductory courses on general relativity, this fact ...
Holographic excited states in AdS black holes
(Springer, 2019-04-03)
We have recently presented a geometry dual to a Schwinger-Keldysh closed time contour, with two equal β/2 length Euclidean sections, which can be thought of as dual to the Thermo Field Dynamics formulation of the boundary ...
Intermediate scalings for solv, nil, and SL2 (R) black branes
(American Physical Society, 2019-05-31)
In this work, we will study black brane solutions that are not translationally invariant in the spatial directions along which it extends. Instead, we require homogeneity, which still allows points along the spatial ...
Pododermatitis in Captive-Reared Black Stilts (Himantopus novaezelandiae)
(American Association of Zoo Veterinarians, 2011-09)
A potential cause of pododermatitis ("bumblefoot") was investigated in captive-reared juvenile black stilts at the Department of Conservation "Kaki Recovery Program" at Twizel, New Zealand. To address the importance of ...
Efficient gravitational lens optical scalars calculation of black holes with angular momentum
(Wiley Blackwell Publishing, Inc, 2020-03)
We provide new very simple and compact expressions for the efficient calculation of gravitational lens optical scalars for Kerr space-time, which are exact along any null geodesic. These new results are obtained recurring ...
