Symmetry in Hyper Suprime-Cam galaxy spin directions
Richard Stiskalek, Harry Desmond
We perform a Bayesian analysis of anisotropy in binary galaxy spin directions in the Hyper-Suprime Cam Data Release 3 catalogue, in response to a recent claim that it exhibits a di…
Challenges to a sharp change in as a solution to the Hubble tension
Indranil Banik, Harry Desmond, Nick Samaras
It has been proposed that the gravitational constant abruptly decreased around 130 Myr ago, making Type Ia supernovae (SNe) in the Hubble flow intrinsically brighter than those…
syren-new: Precise formulae for the linear and nonlinear matter power spectra with massive neutrinos and dynamical dark energy
Ce Sui, Deaglan J. Bartlett, Shivam Pandey +3
Current and future large scale structure surveys aim to constrain the neutrino mass and the equation of state of dark energy. We aim to construct accurate and interpretable symboli…
Dark matter halo properties from spatially integrated HI flux profiles
Tariq Yasin, Harry Desmond
Resolved rotation curves (RCs) are our best probe of the dark matter distribution around individual galaxies. However their acquisition is resource-intensive, rendering them imprac…
Statistical Patterns in the Equations of Physics and the Emergence of a Meta-Law of Nature
Andrei Constantin, Deaglan Bartlett, Harry Desmond +1
Physics seeks to uncover the laws of Nature and express them through mathematical equations. Despite the vast diversity of natural phenomena, physical equations exhibit structural…
On the consistency of rotation curves and spatially integrated HI flux profiles
Tariq Yasin, Harry Desmond
Resolved rotation curves (RCs) are the gold-standard measurements for inferring dark matter distributions in CDM and testing alternative theories of dynamics in galaxies. Howeve…
Testing screened modified gravity with SDSS-IV-MaNGA
Ricardo G. Landim, Harry Desmond, Kazuya Koyama +1
Fifth forces are ubiquitous in modified gravity theories, and must be screened to evade stringent local tests. This can introduce unusual behaviour in galaxy phenomenology by affec…
The Inefficiency of Genetic Programming for Symbolic Regression
Gabriel Kronberger, Fabricio Olivetti de Franca, Harry Desmond +2
We analyse the search behaviour of genetic programming for symbolic regression in practically relevant but limited settings, allowing exhaustive enumeration of all solutions. This…
No evidence for anisotropy in galaxy spin directions
Dhruva Patel, Harry Desmond
Modern cosmology rests on the cosmological principle, that on large enough scales the Universe is both homogeneous and isotropic. A corollary is that galaxies' spin vectors should…
syren-halofit: A fast, interpretable, high-precision formula for the CDM nonlinear matter power spectrum
Deaglan J. Bartlett, Benjamin D. Wandelt, Matteo Zennaro +2
Rapid and accurate evaluation of the nonlinear matter power spectrum, , as a function of cosmological parameters and redshift is of fundamental importance in cosmology. Analy…
