# #Student Seminar: Exploring Dark Matter scenarios through 21 cm cosmology

## by Pablo Villanueva Domingo (IFIC/CSIC-UV)

The redshifted 21 cm line, arising from the hyperfine structure of the Hydrogen, provides a promising tool to study the cosmic evolution from the birth of the first stars until the Epoch of Reionization. Moreover, since it is sensitive to structure formation and thermal history, it allows us to test Dark Matter scenarios such as Warm Dark Matter (WDM) or Primordial Black Holes (PBH), models which leave distinctive imprints in the Intergalactic Medium. The first recent measurement of the 21 cm signal by EDGES, as well as future precision experiments like HERA or SKA, could significantly improve current constraints on these Dark Matter models.
