Late Time Dynamical Dark Energy and the CMB-Distance Ladder Tension
George Efstathiou
The traditional distance ladder measures the standardized peak absolute magnitude M^B of Type Ia supernovae (SNIa). According to the SH0ES collaboration, the distance ladder value…
Baryon Acoustic Oscillations from a Different Angle
George Efstathiou
This paper presents an alternative way of analysing Baryon Acoustic Oscillation (BAO) distance measurements via rotations to define new quantities Dperp and Dpar. These quantities…
Prospects for disentangling dark matter with weak lensing
Calvin Preston, Keir K. Rogers, Alexandra Amon +1
We investigate the degeneracy between the effects of ultra-light axion dark matter and baryonic feedback in suppressing the matter power spectrum. We forecast that galaxy shear dat…
Reconstructing the matter power spectrum with future cosmic shear surveys
Calvin Preston, Alexandra Amon, George Efstathiou
Analyses of cosmic shear typically condense weak lensing information over a range of scales to a single cosmological parameter, . This paper presents a method to extract more…
A non-linear solution to the tension II: Analysis of DES Year 3 cosmic shear
Calvin Preston, Alexandra Amon, George Efstathiou
Weak galaxy lensing surveys have consistently reported low values of the parameter compared to the cosmology. Amon & Efstathiou (2022) used KiDS-…
A non-linear solution to the tension?
Alexandra Amon, George Efstathiou
Weak galaxy lensing surveys have consistently reported a lower amplitude for the matter fluctuation spectrum, as measured by the parameter, than expected in the …
