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…
The Dipole of the Pantheon+SH0ES Data
Francesco Sorrenti, Ruth Durrer, Martin Kunz
In this paper we determine the dipole in the distance redshift relation from the Pantheon+ data. We find that, while its amplitude roughly agrees with the dipole found in the cosmi…
Constraining the bispectrum from bouncing cosmologies with Planck
Bartjan van Tent, Paola C. M. Delgado, Ruth Durrer
Bouncing models of cosmology, as they arise e.g. in loop quantum cosmology, can be followed by an inflationary phase and generate close-to-scale-invariant fluctuation spectra as ob…
Magnetogenesis from early structure formation due to Yukawa forces
Ruth Durrer, Alexander Kusenko
Yukawa interactions can mediate relatively long-range attractive forces between fermions in the early universe. Such a globally attractive interaction creates an instability that c…
