====== Description ======
This group covers cosmic probes of cosmology in the Modern Universe, when galaxies are fully formed. These probes include galaxy clusters, galaxy clustering, redshift space distortions, gravitational lensing, baryonic acoustic oscillations, supernovae and more. Spectroscopic, broad-band and multi-wavelength surveys are examples of experiments that will be primarily discussed in this working group. Other examples include projects involving CMB, 21cm, and gravitational wave observations. 

====== Remote meetings in the run-up to November meeting  ======

Telecons will happen roughly biweekly on Mondays at 1 PM Pacific time (or equivalently 2PM Mountain, 3PM Central and 4PM Eastern times) at:
