Asymptotically flat black holes and gravitational waves in three-dimensional massive gravity
Cédric Troessaert, David Tempo, Ricardo Troncoso
Different classes of exact solutions for the BHT massive gravity theory are constructed and analyzed. We focus in the special case of the purely quadratic Lagrangian, whose field e…
Asymptotically locally flat spacetimes and dynamical black flowers in three dimensions
Glenn Barnich, Cédric Troessaert, David Tempo +1
The theory of massive gravity proposed by Bergshoeff, Hohm and Townsend is considered in the special case of the pure irreducibly fourth order quadratic Lagrangian. It is shown tha…
Asymptotic structure of the Einstein-Maxwell theory on AdS
Alfredo Perez, Miguel Riquelme, David Tempo +1
The asymptotic structure of AdS spacetimes in the context of General Relativity coupled to the Maxwell field in three spacetime dimensions is analyzed. Although the fall-off of the…
Gravitational Collapse of a Homogeneous Scalar Field Coupled Kinematically to Einstein Tensor
George Koutsoumbas, Konstantinos Ntrekis, Eleftherios Papantonopoulos +1
We study the gravitational collapse of a homogeneous time-dependent scalar field that, besides its coupling to curvature, it is also kinematically coupled to the Einstein tensor. T…
Trace Anomaly and Counterterms in Designer Gravity
Andres Anabalon, Dumitru Astefanesei, David Choque +1
We construct concrete counterterms of the Balasubramanian-Kraus type for Einstein-scalar theories with designer gravity boundary conditions in AdS, so that the total action i…
Super-BMS invariant boundary theory from three-dimensional flat supergravity
Glenn Barnich, Laura Donnay, Javier Matulich +1
The two-dimensional super-BMS invariant theory dual to three-dimensional asymptotically flat supergravity is constructed. It is described by a constrained or…
