Description
I will describe how the cosmic-dawn era, which saw the formation of the first galaxies, holds a wealth of information about dark matter and new physics in the early universe. The next decade will see detailed maps of this era with both 21-cm and space telescopes like the new James Webb. I will show how to use the upcoming data to measure dark-matter structure formation at smaller scales—and earlier times—than ever before. I will also describe how, intriguingly, the first JWST observations appear to be in tension with our models, perhaps pointing at new physics at high redshifts.
