Publikováno v: Phys. Rev. D 110, 063519 (2024)

Measurements of the cosmic redshift drift - the change in redshift of a source over time - will enable independent detection of cosmological expansion thanks to the immense precision soon reached by new facilities such as the Square Kilometer Array O

Splitting the spacetime: A systematic analysis of foliation dependence in cosmic averaging

Autor: Mourier, Pierre, Heinesen, Asta

It is a fundamental unsolved question in general relativity how to unambiguously characterize the effective collective dynamics of an ensemble of fluid elements sourcing the local geometry, in the absence of exact symmetries. In a cosmological contex

Reconciling a decelerating Universe with cosmological observations

Publikováno v: Phys. Rev. D 107 (2023) L101301

Can modern cosmological observations be reconciled with a general-relativistic Universe without an anti-gravitating energy source? Usually, the answer to this question by cosmologists is in the negative, and it is commonly believed that the observed

The quadrupole in the local Hubble parameter: first constraints using Type Ia supernova data and forecasts for future surveys

Autor: Dhawan, Suhail, Borderies, Antonin, Macpherson, Hayley J., Heinesen, Asta

The cosmological principle asserts that the Universe looks spatially homogeneous and isotropic on sufficiently large scales. Given the fundamental implications of the cosmological principle, it is important to empirically test its validity on various

In this paper we will list a few important goals that need to be addressed in the next decade, also taking into account the current discordances between the different cosmological probes, such as the disagreement in the value of the Hubble constant $
