Einstein-Maxwell-Dilaton-Axion mass formulas for black holes with struts and strings

Dmitri Gal'tsov, Gérard Clément, Igor Bogush

Mass formulas are obtained for stationary axisymmetric solutions of the Einstein-Maxwell dilaton-axion theory, which have a regular rod structure on the axis of symmetry. Asymptoti…

Palatini kinetic scalar-tensor theory: analytical and numerical solutions

D. V. Gal'tsov, D. S. Bushuev

We investigate static spherically symmetric solutions in the Palatini kinetically coupled scalar-tensor theory, which reduces to gravity minimally coupled to a scalar field in Eins…

Photon regions in stationary axisymmetric spacetimes and umbilic conditions

Kirill Kobialko, Dmitri Gal'tsov

We present the fundamentals of the recently proposed geometric description of photon regions in terms of foliation into fundamental photon hypersurfaces, which satisfies the umbili…

Killing tensors in foliated spacetimes and photon surfaces

Kirill Kobialko, Igor Bogush, Dmitri Gal'tsov

We discuss a recently proposed geometric method for constructing a nontrivial Killing tensor of rank two in a foliated spacetime of codimension one that lifts trivial Killing tenso…

Odd-dimensional gravitational waves from a binary system on a three-brane

D. V. Gal'tsov, M. Khlopunov

We consider gravitational radiation in the presence of non-compact extra dimensions. If their number is odd, all spacetime becomes odd-dimensional and formation of gravitational ra…

Killing tensors and photon surfaces in foliated spacetimes

Kirill Kobialko, Igor Bogush, Dmitri Gal'tsov

We present a purely geometric method for constructing a rank two Killing tensor in a spacetime with a codimension one foliation that lifts the trivial Killing tensors from slices t…
