Janis-Newman-Winicour (JNW) spacetimes generalize the Schwarzschild solution to include a massless scalar field. Although suffering from naked singularities, they share the `frozen star' features of Schwarzschild black holes. Cosmological versions of the JNW spacetimes were discovered some time ago by Husain, Martinez and Nunez and by Fonarev. Unlike Schwarzschild-deSitter black holes, these solutions are dynamical, and the scarcity of exact solutions for dynamical black holes in cosmological… Expand
Critical phenomena in gravitational collapse of Husain–Martinez–Nunez scalar field
We construct analytical models to study the critical phenomena in gravitational collapse of the Husain-Martinez-Nunez massless scalar field. We first use the cut-and-paste technique to match theExpand
Gravitational instabilities and censorship of large scalar field excursions
A bstractLarge, localized variations of light scalar fields tend to collapse into black holes, dynamically “censoring” distant points in field space. We show that in some cases, large scalarExpand
Static dilatonic black hole with nonlinear Maxwell and Yang–Mills fields of power-law type
Static spherically symmetric black hole solution is obtained in the framework of Einstein-dilaton theory with nonlinear Maxwell and Yang–Mills fields of power-law type. It is observed that black holeExpand
Searching for dynamical black holes in various theories of gravity
We construct models of Einstein and $f(R)$ gravity with two scalar fields, which admit analytical solutions describing time-varying dynamical black holes. Their thermodynamics is investigated in theExpand
Spherical inhomogeneous solutions of Einstein and scalar–tensor gravity: A map of the land
Abstract We review spherical and inhomogeneous analytic solutions of the field equations of Einstein and of scalar-tensor gravity, including Brans–Dicke theory, non-minimally (possibly conformally)Expand

These solutions give the first analytic description of coalescing black holes, which describe an arbitrary number of charged black holes in a spacetime with a positive cosmological constant Λ. Expand
Exact Einstein scalar field solutions for formation of black holes in a cosmological setting
We consider self-interacting scalar fields coupled to gravity. Two classes of exact solutions to Einstein's equations are obtained: the first class corresponds to the minimal coupling, the second oneExpand
Global structure and physical interpretation of the Fonarev solution for a scalar field with exponential potential
We discuss the physical interpretation of a dynamical and inhomogeneous spherically symmetric solution obtained by Fonarev for a scalar field with an exponential potential. There is a singleExpand
Charged black holes in string theory with Gauss-Bonnet correction in various dimensions
We study charged black hole solutions in Einstein-Gauss-Bonnet theory with the dilaton field which is the low-energy effective theory of the heterotic string. The spacetime is D-dimensional andExpand
Asymptotically flat black holes with scalar hair: a review
We consider the status of black hole (BH) solutions with nontrivial scalar fields but no gauge fields, in four-dimensional asymptotically flat spacetimes, reviewing both classical results and recentExpand
Holography for Einstein-Maxwell-dilaton theories from generalized dimensional reduction
A bstractWe show that a class of Einstein-Maxwell-Dilaton (EMD) theories are re- lated to higher dimensional AdS-Maxwell gravity via a dimensional reduction over com- pact Einstein spaces combinedExpand

Primordial black hole evolution in tensor scalar cosmology
A perturbative analysis shows that black holes do not remember the value of the scalar field $\phi$ at the time they formed if $\phi$ changes in tensor-scalar cosmology. Moreover, even when the blackExpand
Testing cosmic censorship with black hole collisions.
This investigation is based on a recently discovered exact solution describing the collision of Q=M black holes with \ensuremath{\Lambda}g0, and finds that if the total mass is less than the extremal limit, then the black holes coalesce. Expand
Black holes in the early Universe.
This review reports on basic, but critical, questions regarding the cosmological significance of MBHs and investigates how the growth of black holes is linked to that of their host galaxy. Expand
