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

Understand

Exploring the possibility that fundamental constants of Nature might vary temporally or spatially constitutes one of the key science drivers for the European Southern Observatory's ESPRESSO spectrograph on the VLT and for the HIRES spectrograph on the ELT.

• High-resolution spectra of quasar absorption systems permit accurate measurements of fundamental constants out to high redshifts.
• The quality of new data demands completely objective and reproducible methods.
• We have developed a new fully automated Artificial Intelligence-based method capable of deriving optimal models of even the most complex absorption systems known.
