Do quasars emit gamma rays?
Yes, quasars can emit gamma rays. They are extremely luminous and active galactic nuclei powered by accretion onto supermassive black holes at the centers of galaxies. Gamma-ray emissions from quasars provide valuable information about the high-energy processes occurring in these intense environments.
How long do quasars last?
Quasars, which are highly luminous active galactic nuclei powered by supermassive black holes, can last for billions of years. Their lifespan is influenced by factors such as the availability of gas and dust for accretion onto the black hole. While individual quasars may shine brightly for a significant portion of the universe's history, they eventually may fade as their fuel diminishes. Overall, the active phase of a quasar can last anywhere from tens of millions to several billion years.
What type of nuclei are NMR active?
Nuclei with a non-zero spin quantum number, such as 1/2, 1, or 3/2, are NMR active. Common NMR-active nuclei include 1H, 13C, 19F, and 31P.
What is a distant extremely bright galaxy with the black hole at Center called?
The most luminous and distant objects known to science are called quasars and generally accepted to be the nuclei of active galaxies, or in other words supermassive black holes with their relativistic polar jets aimed towards earth.
What is an active black hole?
An active black hole is a black hole that it by all manner of terms is "feeding". That is, it is accreting matter, or sucking matter into itself. Most black holes are dormant and don't show any signs of accreting matter.

What object in the universe emits microwaves?
Galaxies, specifically those with active galactic nuclei like quasars and radio galaxies, can emit microwaves as a result of the activity in their cores. This can be due to interactions between supermassive black holes and surrounding matter producing jets of high-energy particles that emit microwaves when they interact with the interstellar medium.

How are quasars and black hole different?
One might say a quasar is a highly luminous area powered by a particularly massive black hole. Quasars were once mysterious; the general agreement now is that quasars are active galactic nuclei, whose emissions are powered by the supermassive black hole in the galactic center, the area around the black hole including the accretion disk and polar jets being detectable at great distances due to the immense energy these release. Black holes, by contrast, are not intrinsically luminous; in fact, they earn their name in that they absorb light that falls into them never to be released, and detectable only by their gravitational influence on other bodies, infalling matter, secondary effects, etc.
How is a quasar created?
Quasars, or "Quasi-stellar radio objects", are incredibly distant, extraordinarily bright radio sources. Because they are so distant, we're looking "back in time" to see them as they were billions of years ago. We believe that quasars are - or were - active galactic nuclei, when the galaxies were forming their central supermassive black holes. If we could look back in time by 5 billion years, we would probably see a similar occurance here in the Milky Way. And if we could see those quasars as they are today - instead of seeing the light and radiation that they were generating when that light was new - we'd probably see that the object was a fairly ordinary galaxy with an "ordinary" super-massive black hole at the center.
What is a very energetic distant object that may be powered by a black hole?
A quasar is a very energetic distant object that is powered by a supermassive black hole at its center. The intense radiation emitted from the accretion disk around the black hole can outshine the entire galaxy in which the quasar is located.
