Is a quasar a one off phenomenon at the inception of a galaxy, or does a super massive black hole produce quasars repeatedly as a by-product when there is too much matter to be absorbed.
Matt Todd said:Thanks Drakkith. I wonder then if the collision of the Milky Way and Andromeda would create this scenario.
I honestly don't know enough about galaxy evolution to say for sure. However, I would say that the observation of jets of matter coming from the center of our own Milky Way demonstrate that its black hole has been active in the relatively recent past (cosmologically speaking).TheTechNoir said:Is that a prediction or has there been any observational evidence to lend credence to the belief?

Matt Todd said:Okay, so it's looking as though quasars aren't a one off, they seem to depend on availability of matter, dense and abundant matter being the trigger?
Yes, it is possible for quasars to reactivate within an established galaxy. Quasars are powered by supermassive black holes at the center of galaxies, and they can become dormant when they run out of nearby gas to fuel their activity. However, if more gas is accreted onto the black hole, the quasar can reactivate.
The reactivation of a quasar can vary in time, and it largely depends on the availability of gas. It could take anywhere from millions to billions of years for a quasar to reactivate within a galaxy.
Yes, a quasar's reactivation can have a significant impact on the surrounding galaxy. The energy and radiation emitted by the quasar can affect the galaxy's gas dynamics, star formation, and overall structure.
Yes, there are observable changes when a quasar reactivates. As the quasar becomes active again, it emits intense radiation across the electromagnetic spectrum, which can be detected by telescopes. The galaxy's appearance and characteristics may also change due to the quasar's influence.
Yes, it is possible for quasars to reactivate multiple times within the same galaxy. As long as there is enough gas to fuel the black hole, it can undergo multiple cycles of activity and dormancy. This process can also contribute to the growth and evolution of the galaxy over time.
