| Massive black holes (MBHs) play a pivotal role in shaping the evolution of galaxies. Their population is remarkably diverse in the local Universe, spanning from those hosted by dwarf galaxies to the largest ellipticals. At high redshift, however, until recently, we were limited to detecting only the brightest quasars, powered by MBHs weighing billions of solar masses as early as 700 million years after the Big Bang. In less than 2 years of operation, the James Webb Telescope has already uncovered the presence of several dozen fainter active MBHs in the early Universe. In this talk, I will discuss the current theoretical pathways for the origins of the first MBHs, the recent discoveries made by JWST, and their agreement with results from the large-scale cosmological simulations of the field. |
