Perturbations of Cosmological Redshift Drift
Pedro Bessa, Ruth Durrer, Dennis Stock
In this paper we calculate the linear perturbations of the cosmological redshift drift. We show explicitly that our expressions are gauge-invariant and compute the power spectrum o…

The Hawking Energy in a Perturbed Friedmann-Lemaître Universe
Dennis Stock, Enea Di Dio, Ruth Durrer
Hawking's quasi-local energy definition quantifies the energy enclosed by a spacelike 2-sphere in terms of the amount of lightbending on the sphere caused by the energy distributio…

Backreaction from gauge fields produced during inflation
R. Durrer, O. Sobol, S. Vilchinskii
In this work, we study general features of a regime where gauge fields produced during inflation cause a strong backreaction on the background evolution and its impact on the spect…
