New Probes of Cosmology

We explore a tasting menu of new advances in probing cosmology:
  1. DESI and gravitional waves
  2. DESI and inflation
  3. Direct acceleration through cosmic redshift drift
  4. Strong gravitational lensing

We also discuss some generally applicable new tools, such as our competition winning machine learning for crosscorrelating noisy data (e.g. measuring time delays, exoplanets), optimizing leverage under a fixed resource constraint (wide field survey followup), and the new likelihood mapper MultiTracer to replace MCMC.
