We show that detecting heavy seeds at z>10 in the next decade will be feasible with upcoming and/or proposed facilities. Their detection will be fundamental to understand the early history of the Universe and its evolution.ELETTRONICOenArticlehttps://baas.aas.org/pub/2020n3i117/release/12019BAAS...51c.117PFIS/05 - ASTRONOMIA E ASTROFISICA
