How many quasars are in a galaxy?
Typically, a galaxy may contain one or a few quasars. Quasars are incredibly luminous objects powered by supermassive black holes at the centers of galaxies. They are rare and only occur under specific conditions, so it is not common for a galaxy to have multiple quasars.
What do astronomers use to study quasars?
Astronomers use telescopes, both ground-based and space-based, to study quasars. They observe the light emitted by quasars across different wavelengths, such as visible, ultraviolet, and X-ray, to learn more about their properties and behavior. Additionally, they analyze the spectra of quasars to understand their composition and the physical processes happening within them.
Are quasars possible?
Yes they are. Thanks mainly to the Sloan Digital Sky Survey, more than 200,000 quasars are known.
What does it mean that quasars are most common at a redshift of about 2?
Quasars being most common at a redshift of around 2 means that they were more prevalent in the universe's past. The redshift indicates their distance and age, suggesting that quasars were more abundant when the universe was younger. This redshift value corresponds to a time when many galaxies were undergoing intense star formation and black hole activity, leading to more quasars.
Quasars have what kind of spectral lines?
Quasars have all kinds of spectral lines namely more energetic ones which makes them the brightest objects in the night sky.

Quasars are high-energy galaxies.?
More precisely, quasars are high-energy galaxy CORES, compact enough to appear starlike, yet emitting more radiation than a million "ordinary" galaxies.
Are distant objects in space called quarks or quasars?
quasars

How a quasars are formed?
Quasars are thought to be distant super-massive black holes.
What year were quasars first discovered?
The first quasars were discovered in the 1950's
Are quasars the size of the solar system?
Yes. Quasars are the size of the solar system.
Where can one learn more about fluid handling?
