A)when there was still enough dark matter to fuel the supermassive black holes in their bar.
B)when there was still sufficient mass to fuel the supermassive black holes at their center.
C)before the formation of galaxies.
D)before the star formation epoch.
E)before mass had a chance to accumulate at the nucleus.

Question

Quizplus · Accepted Answer

The quasar epoch was fueled by supermassive black holes at the center of galaxies, and the peak was when there was still enough mass to fuel these black holes. Therefore, choice B is the most accurate answer. Choices A, C, D, and E are not as accurate or precise. Quasars are powered by accretion onto supermassive black holes at the center of galaxies. The peak of the quasar epoch corresponds to the time when there was still enough mass in the centers of galaxies to fuel these black holes and produce the intense radiation emission characteristic of quasars. Therefore, choice B is the best answer. Choices A, C, D, and E are all incorrect as they do not accurately describe the conditions that contributed to the peak of the quasar epoch.
