Kundt spacetimes in the Gauss-Bonnet Gravity
Ondrej Hruska, Jiri Podolsky
The Gauss-Bonnet gravity is a special case of so-called Quadratic Gravity, which is an extension of Einstein's theory with additional terms in action that are quadratic combination…

Penrose junction conditions extended: impulsive waves with gyratons
Jiri Podolsky, Robert Svarc, Roland Steinbauer +1
We generalize the classical junction conditions for constructing impulsive gravitational waves by the Penrose "cut and paste" method. Specifically, we study nonexpanding impulses w…

Yet another family of diagonal metrics for de Sitter and anti-de Sitter spacetimes
Jiri Podolsky, Ondrej Hruska
In this work we present and analyze a new class of coordinate representations of de Sitter and anti-de Sitter spacetimes for which the metrics are diagonal and (typically) static a…
