This group covers cosmic probes of cosmology in the early Universe from Inflation Era through the Cosmic Dawn. Subtopics include: growth of structure probes (e.g. 21cm power spectrum in the dark ages), probes of expansion history (e.g. BAO with black hole mergers, CMB), primordial non-gaussianity and inflation. High-z gravitational wave observatories, 21cm and CMB projects are examples of experiments expected to be primarily discussed here. Overlaps with the previous section are expected.

Here is the list of submitted LOIs to this topic. First index before “/” corresponds to the primary frontier used for the submission.
