A hide-and-seek game: Looking for Population III stars during the Epoch of Reionization through the HeII$\lambda$1640 line

Alessandra Venditti, Volker Bromm, Steven L. Finkelstein +4

The gas surrounding first-generation (Pop III) stars is expected to emit a distinct signature in the form of the HeII recombination line at 1640 Å (HeII$\lambda$1640). Here we explore th…
