Artificial intelligence and quasar absorption system modelling; application to fundamental constants at high redshift

no code implementations6 Aug 2020 Chung-Chi Lee, John K. Webb, R. F. Carswell, Dinko Milakovic

We also argue that model non-uniqueness can be significant, such that it is not feasible to expect to derive an unambiguous estimate of the fine structure constant alpha from one or a small number of measurements.
