Cosmography for a General Spacetime Centred at Arbitrary Redshift
Jonas Broe Bendtsen, Asta Heinesen, Sofie Marie Koksbang
With upcoming surveys providing large volumes of highly precise observational data across a wide range of redshifts, it is increasingly important to have tools that can translate o…
Post-Newtonian Global Conservation Laws in the Presence of Sensitive Bodies
Timothy Clifton, Asta Heinesen, Oliver Pitt
The parameterized post-Newtonian (PPN) approach is the state of the art formalism for performing theory independent tests of weak-field gravity, and for constraining possible devia…
Mapping the Universe as a Bianchi I cosmology with Gaia data
Valeri V. Makarov, Asta Heinesen, Thomas Schücker
Measurements of tangential drifts of distant quasars and galactic nuclei on the celestial sphere provide a novel and independent method of testing cosmological hypotheses. In this…
Observational Quantities in Quasi-Newtonian Descriptions of Cosmological Space-Times
Asta Heinesen, Davide Fontana, Timothy Clifton
We investigate measures of distance and redshift in cosmological space-times that admit a shear-free foliation, which we henceforth refer to as `quasi-Newtonian'. Space expands iso…
Observational Tests for Distinguishing Classes of Cosmological Models
Asta Heinesen, Timothy Clifton
We investigate observational tests that can be used to distinguish between broad classes of cosmological models. This is achieved using curvature-consistency tests of the Friedmann…
Diagnostic Consistency Tests of the Concordance Cosmology
S. M. Koksbang, A. Heinesen
The CDM cosmological model faces increasingly significant and robust tensions among independent cosmological probes, prompting renewed scrutiny of its foundational assumptions.…
Model-independent constraints on generalized FLRW consistency relations with bootstrap-based symbolic regression
S. M. Koksbang, A. Heinesen
The standard CDM cosmological model faces increasing tensions between key observations, motivating tests that probe its underlying assumptions. In a companion letter, we present…
Cosmography with -Szekeres Models
Morag Hills, Asta Heinesen
The cosmological tensions present in the cold dark matter model that have emerged and strengthened over recent years motivate model independent approaches to analysing data. Co…
