Bilocal geodesic operators as a tool of investigating the optical properties of spacetimes
Julius Serbenta
In my thesis, I present one particular example of the formalism capable of describing the propagation of a family of light rays in a curved spacetime. It is based on the resolvent…
Bilocal geodesic operators in static spherically-symmetric spacetimes
Julius Serbenta, Mikołaj Korzyński
We present a method to compute exact expressions for optical observables for static spherically symmetric spacetimes in the framework of the bilocal geodesic operator formalism. Th…
Testing the null energy condition with precise distance measurements
Mikołaj Korzyński, Julius Serbenta
We present an inequality between two types of distance measures to a single source in general relativity. It states that for a given emitter and observer the distance between them…
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 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…
