Dynamic or Systematic? Bayesian model selection between dark energy and supernova biases
A. N. Ormondroyd, W. J. Handley, M. P. Hobson +2
The Dark Energy Survey 5-year (DES-5Y) supernovae, combined with Dark Energy Spectroscopic Instrument (DESI) baryon acoustic oscillations, appear to favour Chevallier-Polarski-Lind…
Nonparametric reconstructions of dynamical dark energy via flexknots
A. N. Ormondroyd, W. J. Handley, M. P. Hobson +1
Recent cosmological surveys have provided unprecedented datasets that can be used to reconstruct the history of the dark energy equation of state. In this work, a free-form "flexkn…
Comparison of dynamical dark energy with ΛCDM in light of DESI DR2
A. N. Ormondroyd, W. J. Handley, M. P. Hobson +1
We present an updated reconstruction of the dark energy equation of state, , using the newly released DESI DR2 Baryon Acoustic Oscillation (BAO) data in combination with Pant…
Tilting the scales: weighing prior dependency and global tensions of CMB lensing
A. N. Ormondroyd, W. J. Handley, M. P. Hobson +1
We provide a nested sampling analysis of the combination of CMB lensing experiments with other cosmological measurements. Nested samples can be used to compute global consistency s…
