Isolating non-linearities of light propagation in inhomogeneous cosmologies
Michele Grasso, Eleonora Villa, Mikołaj Korzyński +1
A new formulation for light propagation in geometric optics by means of the Bi-local Geodesic Operators is considered. We develop the BiGONLight Mathematica package, uniquely desig…
Weighing the spacetime along the line of sight using times of arrival of electromagnetic signals
Mikołaj Korzyński, Jan Miśkiewicz, Julius Serbenta
We present a new method of measuring the mass density along the line of sight, based on precise measurements of the variations of the times of arrival (TOA's) of electromagnetic si…
Geometric optics in relativistic cosmology: new formulation and a new observable
Mikołaj Korzyński, Eleonora Villa
We discuss a new formalism for light propagation which can be used within the regime of validity of geometric optics, but with no limitation on the scales of interest: from inside…
Variational principle for the Einstein-Vlasov equations
Lars Andersson, Mikołaj Korzyński
The Einstein-Vlasov equations govern Einstein spacetimes filled with matter which interacts only via gravitation. The matter, described by a distribution function on phase space, e…
Geometric optics in general relativity using bilocal operators
Michele Grasso, Mikołaj Korzyński, Julius Serbenta
We consider the standard problem of observational astronomy, i.e. the observations of light emission from a distant region of spacetime in general relativity. The goal is to descri…
