All active galaxies are formed by the interaction of more than one galaxy

Disturbance galaxies are a classification of active galaxies. () stuffy or.

a.Zhengzhen stockings are exciting.

b.Mistake. Correct Answer: a

Quasars and active galaxies are two different things.

Let's start with quasars, which are the most dangerous objects in the universe and are themselves caused by a supermassive black hole. There is an upper limit to the matter that can be swallowed by any black hole, and when the matter that a supermassive black hole can absorb reaches its upper limit, if it is still devouring a large amount of matter, the matter that cannot be contained will be spit out by the black hole after falling into the black hole and sprayed into space, forming an extremely large energy stream. These streams of energy spit out by black holes are called quasars.

In short, you can think of quasars as substances that a black hole spits out after eating too much.

Active galaxies refer to a special class of galaxies, i.e., galaxies that are undergoing intense evolution within themselves. If stars inside a galaxy are forming on a large scale (starburst galaxies), galaxies that are colliding and merging with each other, galaxies with strong activity in galactic nuclei, planets with quasars in the center, etc. In short, all galaxies that are in a state of "excitement" are called active galaxies.

Our Milky Way is obviously not an active galaxy, it has no quasars, no stars are forming on a large scale, and the galactic core is not very active, so the Milky Way is a stable galaxy. On the other hand, the M87 galaxy is also an active galaxy because there is a quasar eruption stream in its center, and the activity in the center is very intense.

Active galaxies are a general term for a certain type of galaxy, just like some people have "ADHD", whether the last galaxy is active or not has nothing to do with its own shape, size, color, etc.

The evolution path of active galaxies mainly includes: through the form of Bl Scorpio or radio stars, they eventually evolve into elliptical galaxies in normal galaxies; It first evolved into the Frontal Seifert Galaxy, and then further evolved into the Spiral Galaxy in a normal galaxy.

10% of galaxies are active galaxies, and the main characteristics of active galaxies are: there is a very small and extremely bright nucleus in the central region of the galaxy, called the active galactic nucleus; strong non-thermal continuum; There are wide emission lines in the spectrum.

Some active galaxies have rapid light changes, with time scales ranging from a few hours to several years. Some active galaxies have obvious eruptions, such as jets. Most of the characteristics of active galaxies are associated with active galactic nuclei.

Active galaxies, also known as agitated galaxies, are galaxies with violent activity or violent physical processes, including Seifert galaxies, quasars, radio galaxies, manticores, and starburst galaxies.

The fact that most of the active galaxies are located at great distances suggests that they are young objects in the universe, as their light travels millions or even billions of years to reach Earth. This has led astronomers to believe that probably all galaxies have gone through this phase of activity.

It first evolved into the Seifert galaxy, and then further evolved into a spiral galaxy within a normal galaxy, and finally evolved into an elliptical galaxy in a normal galaxy through the form of a Scorpio Tigerid or a radio star.

The active galactic nucleus is a bright and dense region at the center of the active galaxy, and its radiation covers almost the entire electromagnetic band, from the low-energy radio band to the high-energy gamma-ray band.

Since radio band radiation is not affected by dust absorption, radio photometric function becomes an effective tool for studying the evolution of active galactic nuclei. However, due to the incompleteness of the radio observation samples of active galactic nuclei and the limitations of statistical methods, there is a large uncertainty in the calculation of radio photometric functions. The research work completed by Yuan Zunli and Wang Jiancheng provides important evidence for revealing the density distribution and accretion process of supermassive black holes.

The Astrophysical Journal, an internationally renowned astrophysical journal.

The results of the research work of Yuan Zunli, Wang Jiancheng and others from the Yunnan Astronomical Observatory of the Chinese Academy of Sciences were published, and they used the Bayesian method to reliably calculate the radio luminosity of the active galactic nucleus, and confirmed that the active galactic nucleus has a mixed evolution mode of density and luminosity, in which the density evolution peaks at a redshift of about 1 and then slowly decreases.

The photometric evolution continues to a higher redshift (3 - 5) and then decreases. It is precisely under the combined action of density evolution and photometric evolution that the active galactic nuclei exhibit photometric-dependent density evolution characteristics, that is, the evolution of low-luminosity sources tends to flatten or even stops evolution at about 1 redshift, while the strong evolution of high-luminosity sources continues until about 3 redshifts.
