New Probes of Cosmology
We explore a tasting menu of new advances in probing cosmology:
- DESI and gravitional waves
- DESI and inflation
- Direct acceleration through cosmic redshift drift
- 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.
