General Relativistic Effects in Weak Lensing Angular Power Spectra
Nastassia Grimm, Jaiyul Yoo
Advances in upcoming weak lensing surveys pose new challenges for an accurate modeling of the lensing observables. The wide sky coverage of Euclid makes angular scales down to $l_\…
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…
Galaxy Power Spectrum in General Relativity
Nastassia Grimm, Fulvio Scaccabarozzi, Jaiyul Yoo +2
We present the galaxy power spectrum in general relativity. Using a novel approach, we derive the galaxy power spectrum taking into account all the relativistic effects in observat…
