When young galaxies are first formed, they’re accompanied by tremendous bursts of star formation, giving rise to billions of new stars within just a few million years. Yet how these galaxies first form in the initial stages is very much an open question. In addition, pretty much every large galaxy we find — even in the extremely young Universe — has a supermassive black hole at its center.

Is it conceivable that these black holes are the engines of newly formed galaxies? Is it even possible that these black holes preceded the galaxies, and enabled them to form in the first place? It’s a big quasar-fueled question on this edition of Astroquizzical.
