Deformations of GR, Geometrodynamics and Reality Conditions
Kirill Krasnov, Ermis Mitsou
In four dimensions complexified General Relativity (GR) can be non-trivially deformed: There exists an (infinite-parameter) set of modifications all having the same count of degree…
Cutting out the cosmological middle man: General Relativity in the light-cone coordinates
Ermis Mitsou, Giuseppe Fanizza, Nastassia Grimm +1
Analytical computations in relativistic cosmology can be split into two sets: time evolution relating the initial conditions to the observer's light-cone and light propagation to o…
Tetrad formalism for exact cosmological observables
Ermis Mitsou, Jaiyul Yoo
The standard description of cosmological observables is incomplete, because it does not take into account the correct angular parametrization of the sky, i.e. the one determined by…
Cosmological Information Contents on the Light-Cone
Jaiyul Yoo, Ermis Mitsou, Nastassia Grimm +2
We develop a theoretical framework to describe the cosmological observables on the past light cone such as the luminosity distance, weak lensing, galaxy clustering, and the cosmic…
: A New Cosmological Parameter?
Jaiyul Yoo, Ermis Mitsou, Yves Dirian +1
The background photon temperature is one of the fundamental cosmological parameters. Despite its significance, has never been allowed to vary in the data analysis…
General and consistent statistics for cosmological observations
Ermis Mitsou, Jaiyul Yoo, Ruth Durrer +2
This paper focuses on two aspects of the statistics of cosmological observables that are important for the next stages of precision cosmology. First, we note that the theory of red…
