This chapter discusses several other ways to probe structures during the cosmic dawn. It first turns to secondary anisotropies of the cosmic microwave background, which are generated as the photons passed through gas during the cosmic dawn. Next, the chapter turns to diffuse backgrounds from the cosmic dawn, which typically include galactic emission lines, ranging from CO lines in the radio to the Lyman-α‎ line itself. Finally, the chapter observes that fossil structure from early galaxies remains in (or can be deduced from) the Milky Way or other nearby entities in the Local Group. This fossil structure includes the residual effects of feedback on the small satellite galaxies or globular clusters of the Milky Way, old low-mass stars that may have formed during the cosmic dawn and survive inside the Milky Way (or its halo), and remnant signatures of the early merger history of the Milky Way.

Keywords:   first galaxies, galactic emission lines, secondary anisotropies, cosmic microwave background, cosmic dawn, early galaxies, fossil structure, star formation, fossil records, Milky Way
