« Two decades of z>6 quasar hunt: Achievements, failures, and new hopes »

Roberto Decarli

Since their first discovery about 20 years ago, luminous quasars at cosmic dawn have proven to be exceptional tools to investigate how massive black holes formed, how the first massive galaxies and large-scale structures assembled, and what physical processes shaped the Universe at its last phase transition (the epoch of reionization). In this talk I will review how the search for a new quasar frontier has evolved in the last twenty years, and address some of the lessons we learned so far from the discovered quasars. I will discuss some of the new and old (but lingering) open puzzles. Finally, I will provide an outlook from a biased observer's perspective on what we should expect from the field in the coming years, as new facilities offer unprecedented, exciting opportunities to study massive black holes in the infancy of galaxy formation.
