Professor Tamara Davis and Ryan Camilleri

The last two years have revealed interesting hints into the nature of dark energy. Both supernova and baryon acoustic oscillation data suggest that the equation of state of dark energy might be time varying, in contrast to the standard cosmological model in which it would be a cosmological constant. A new paper led by UQ’s Ryan Camilleri unites the major supernova data sets and combines them with other probes to put the tightest constraints yet on dynamical dark energy. In this talk, Tamara Davis reviews the evidence for time-varying dark energy and other results from the Dark Energy Survey (DES) and the Dark Energy Spectroscopic Instrument (DESI), and Ryan Camilleri discusses these latest results and their implications.

Carmen Martinez Harris

In this talk, Carmen Martinez Harris presents SpecML, a self-supervised foundation model that learns general representations of galaxy spectra from unlabelled data and transfers them to tasks where labels are scarce. The model adapts the OmniSpectra architecture for use with JWST NIRSpec prism spectra drawn from the DAWN archive, extending these representations to redshift recovery, source classification, and galaxy property estimation.
