Bessel-Hagen currents for linearised Weyl-squared gravity
Michael Hobson, Will Barker, Anthony Lasenby
For the Fierz-Pauli action the Bessel-Hagen construction does not produce a preferred local gauge-invariant energy-momentum tensor; it identifies only a gauge-invariant equivalence…
Numerical polology: towards next-generation model-building for cosmology
Will Barker, Will Handley, Michael Hobson +4
The dark sector need not be restricted to simple field content. Indeed, simple bosonic configurations, such as scalar-tensor or dark photon models, contrast with the much richer pi…
Bessel-Hagen currents for the Fierz-Pauli action
Michael Hobson, Will Barker, Anthony Lasenby
For electromagnetism in Minkowski spacetime, the Bessel-Hagen method gives a particularly direct Noetherian derivation of the standard gauge-invariant energy-momentum tensor. The k…
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…
