The Epoch of Reionization(EoR)poses a number of puzzles,including the sufficiency of ionizing radiation,the rapid production of supermassive black holes and the early appearance of abundant metals in larger galaxies.For the first of these,solutions focus on the main sequence evolution of massive stars,but the second and third puzzles involve the terminal phase of stellar evolution,
The Epoch of Reionization （EoR） poses a number of puzzles, including the sufficiency of ionizing radiation, the rapid production of supermassive black holes and the early appearance of abundant metals in larger galaxies. For the first of these, solutions focus on the main sequence evolution of massive stars, but the second and third puzzles involve the terminal phase of stellar evolution, and in particular, core collapse supernovae.
