A Lower Bound on the Number of Fundamental Constants
William Luke Matthewson
We describe here, for the first time, a lower bound on the total number of fundamental constants required for a mathematical description of our physical universe to be complete. Th…
Isotropy Test with Quasars Using Method of Smoothed Residuals
Akhil Antony, Stephen Appleby, William L Matthewson +1
To assess the significance and scale dependence of anomalous large scale modes in the CatWISE quasar data, we generate smoothed number density fields on the sphere and study their…
Star-Crossed Labours: Checking Consistency Between Current Supernovae Compilations
William L. Matthewson, Arman Shafieloo
We make use of model-independent statistical methods to assess the consistency of three different supernova compilations: Union3, Pantheon+ and DES 5-year supernovae. We expand the…
Could We Be Fooled about Phantom Crossing?
Ryan E. Keeley, Arman Shafieloo, William L. Matthewson
Recent data from DESI Year 2 BAO, Planck CMB, and various supernova compilations suggest a preference for evolving dark energy, with hints that the equation of state may cross the…
