Reconciling a decelerating Universe with cosmological observations

Asta Heinesen

Can modern cosmological observations be reconciled with a general-relativistic Universe without an anti-gravitating energy source? Usually, the answer to this question by cosmologi…

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

Suhail Dhawan, Antonin Borderies, Hayley J. Macpherson +1

The cosmological principle asserts that the Universe looks spatially homogeneous and isotropic on sufficiently large scales. Given the fundamental implications of the cosmological…

Redshift drift in a universe with structure I: Lemaitre-Tolman-Bondi structures with arbitrary angle of entry of light

Sofie Marie Koksbang, Asta Heinesen

We consider the redshift drift and position drift associated with astrophysical sources in a formalism that is suitable for describing emitters and observers of light in an arbitra…

Cosmology Intertwined: A Review of the Particle Physics, Astrophysics, and Cosmology Associated with the Cosmological Tensions and Anomalies

Elcio Abdalla, Guillermo Franco Abellán, Amin Aboubrahim +200

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…

The averaging problem on the past null cone in inhomogeneous dust cosmologies

Thomas Buchert, Henk van Elst, Asta Heinesen

Cosmological models typically neglect the complicated nature of the spacetime manifold at small scales in order to hypothesize idealized general relativistic solutions for describi…
