Redshift drift as a model independent probe of dark energy
Asta Heinesen
It is well known that positive values of redshift drift is a signature of dark energy within the conventionally studied Friedmann-Lema\^ıtre-Robertson-Walker (FLRW) universe models…
Multipole decomposition of redshift drift -- model independent mapping of the expansion history of the Universe
Asta Heinesen
We consider redshift drift in a general space-time as expressed in terms of physically interpretable multipole series. An important realisation from the derived results is that red…
Cosmological homogeneity scale estimates are dressed
Asta Heinesen
We investigate number count statistics as measures for transition to homogeneity of the matter distribution in the Universe and analyse how such statistics might be `dressed' by th…
Solving the curvature and Hubble parameter inconsistencies through structure formation-induced curvature
Asta Heinesen, Thomas Buchert
Recently it has been noted by Di Valentino, Melchiorri and Silk (2019) that the enhanced lensing signal relative to that expected in the spatially flat CDM model poses a possibl…
Quantifying the accuracy of the Alcock-Paczynski scaling of baryon acoustic oscillation measurements
Asta Heinesen, Chris Blake, David L. Wiltshire
We investigate - in a generic setting - the regime of applicability of the Alcock-Paczynski (AP) scaling conventionally applied to test different cosmological models, given a fiduc…
Dynamical spatial curvature as a fit to type Ia supernovae
Célia Desgrange, Asta Heinesen, Thomas Buchert
Few statements in cosmology can be made without assuming a cosmological model within which to interpret data. Statements about cosmic acceleration are no exception to this rule, an…
