G-Bounce
Damien A. Easson, Ignacy Sawicki, Alexander Vikman
We present a wide class of models which realise a bounce in a spatially flat Friedmann universe in standard General Relativity. The key ingredient of the theories we consider is a…
Non-Stationary Dark Energy Around a Black Hole
Ratindranath Akhoury, David Garfinkle, Ryo Saotome +1
Numerical simulations of the accretion of test scalar fields with non-standard kinetic terms (of the k-essence type) onto a Schwarzschild black hole are performed. We find a full d…
The Imperfect Fluid behind Kinetic Gravity Braiding
Oriol Pujolas, Ignacy Sawicki, Alexander Vikman
We present a standard hydrodynamical description for non-canonical scalar field theories with kinetic gravity braiding. In particular, this picture applies to the simplest galileon…
