In simple terms, is this what a quasar is?

Question

When a black hole starts pulling the matter of a star into its vortex, all of the matter starts traveling faster and faster and becomes very hot, which becomes very bright. So when they see those bright objects, is that a quasar?

Answer 1

The gigantic star theoreticians would cringe. The black hole
is generally defined as a collapsed star with orbitting debris.
The quasar on the otherhand is bought and sold on the stock
market because the greatest forces make due with the site
as it needs time frames, operational and equippers. To add a
quasar to the folder of equipped Babylonia stargates would be
a nice answer, and inhabitable within one year. You buying a
station in quasar form is however over 40,000 years ago in
astronomy properties. Yet only .5 of one percent is found in
this frontier system. Quasar findings of the black hole could
be positive shaped as you mention, then becoming a nominate.

Answer 2

A quasar (contraction of QUASi-stellAR radio source) is an astronomical source of electromagnetic energy, including light, which shows a very high redshift. The scientific consensus is that this high redshift is the result of Hubble's law. This implies that quasars are very distant. To be observable at that distance, the energy output of quasars must dwarf that of almost every known astrophysical phenomenon with the exception of comparatively short-lived supernovae and gamma-ray bursts. They may readily release energy in levels equal to the output of hundreds of average galaxies combined. The output of light is equivalent to one trillion suns.

In optical telescopes, most quasars look like single points of light (i.e. point source) although some are seen to be the centers of active galaxies.

Some quasars display rapid changes in luminosity, which implies that they are small (an object cannot change faster than the time it takes light to travel from one end to the other; but see quasar J1819+3845 for another explanation). The highest redshift currently known for a quasar is 6.4. [1]

Quasars are believed to be powered by accretion of material onto supermassive black holes in the nuclei of distant galaxies, making these luminous versions of the general class of objects known as active galaxies. No other currently known mechanism appears able to explain the vast energy output and rapid variability.

Knowledge of quasars is advancing rapidly. As recently as the 1990's there was no clear consensus as to their origin.

Answer 3

Quasars are believed to be supermassive black holes consuming large amounts of gas with their polar jets oriented in our direction. That gas could be from a star but does not have to be.

Also, you are not simply seeing the hot accretion disk as your outline implies. You are seeing the relativistically beamed jets oriented in our direction.

Read about Active Galactic Nuclei here: it corroborates what I just said.

Answer 4

A quasar is incredibly a shiny output of huge black holes in the middle of galaxies. they are in basic terms modern-day in distance galaxies, because of the fact there substitute into greater be counted for the galactic black holes to suck in throughout the early universe.
