How Do Quasars Create Black Holes?

A quasar is a tremendously luminous compact stellar body, where a dense, hot super Stellar black hole with a relative mass ranging from a few million to millions of solar units is enclosed by a luminous gaseous cloud. The name was derived from the German word quest, meaning “shining.” Although the term quasar is now commonly used, no one really knows what it means. Astronomy textbooks usually refer to them as a “galaxy” or a “supermassive” nucleus, but these terms are sometimes used colloquially and in non-astronomy contexts.

Astronomy textbooks do describe quasars in great detail, giving specific names to over one hundred different types. 

Many, like astronomer Edwin Landau’s famous description of our Milky Way galaxy, are used in reference to both bulges, or disks, and their connection to each other and the larger immaterial globular clusters. Others are used only in diagrams, such as spiral disks and Hubble spaces, to illustrate how different types of matter might be pulled into and pushed out of a black hole at different speeds. Astronomy textbooks rarely give a detailed description of the inner properties of quasars.

Most astronomers agree that there are many distinct types of quasars, with varying brightness and composition. 

Some are very hot, emitting powerful infrared radiation, while others have very low relative brightness, and are relatively cool clouds of gas. Astronomy books generally describe several types of quasars with their unique properties, although many astronomers are still trying to determine the nature of the first few hundred such objects which were discovered during the late 1990s.

Astronomers think that there are several hundred compact celestial bodies which must lie beyond the border of the main Galaxy. Many astronomers also think that many such compact objects are rapidly spinning and emitting extended gamma rays. In addition to these long-established facts, some astronomers have built models of the early Universe which include a number of quasars. The first model discovered was a disk galaxy, thought to be so old it predates the birth of the Universe.

The majority of astronomers think that quasars are extremely faint and dim, with wavelengths ranging from very bright to faint. 

Objects which possess a large amount of carbon can absorb light, producing a glow of yellow or red. If such objects are very close to a bright star, their brightness will be enhanced, increasing the contrast between the background and the quasar. Distinguishing quasars are much easier if they are close to a cooler object, for which the effect of a moving plasma will diminish. This can be done by using a Very Hot Lensing experiment, where a quasar with a jet of plasma is imaged at a distance of nearly one light year.

The first telescopes to discover quasars were made to study Very Long Duration Extragalactic Objects (VLDE), which are thought to be incredibly rare compact dwarf satellites. 

Through the use of a combination of radio, optical, and x-ray observations, astronomers were able to determine that these objects were indeed quasars. Since then, with ever-increasing technological development, astronomers have been able to detect a vast number of celestial objects through the use of more sensitive instruments. Astronomy publications frequently report these discoveries, which allow us to better understand the faraway world around us.

Quasars are thought to be made of a material unlike anything we know on earth, as they consist essentially of empty space. 

Because of this, astronomers use a variety of techniques to detect their existence. One method involves detecting the change in a star’s brightness when it passes through a quasar, using a variety of powerful spectrographs. Different types of spectra can provide astronomers with different amounts of information about the composition of space objects, allowing astronomers to determine if there is a black hole present. 

Another technique relies on the properties of gases to identify dark holes. A variety of other methods have also been used to find quasars, including creating a model that mimics a gas cloud surrounding a quasar and comparing the properties of its atmosphere to ours, which should give scientists a good estimate of the object’s composition.

Although scientists have never actually seen a quasar, they can learn much about them by studying the spectrum of radiation emitted by them. 

The spectrum of radiation includes all of the components that make up visible light, with red being the dominant hue and having a relatively high redshift relative to blue. With all the different wavelengths of visible light and the high redshift of quasars, it is easy to see how they would create a strong impact on our visible universe. By studying the spectrum of radiation emitted by quasars, we can learn more about the universe and what it consists of.
