Telescope Chandra observes two red galaxies nuggets
The group of galaxies red Nuggets scientists discovered more than a decade ago, this group includes not large in the number of stars clusters, but at the same time in the galaxies of these simply huge stars and with their small size galaxies are considered massive. In these galaxies there are many red giants, stars of this type and for this reason they are called in a different way - "red nuggets". Recently, the scientific world has again turned its eyes in the direction of this type of galaxies, now the cluster of Red Nuggets is studying the orbital telescope NASA Chandra, a telescope that catches the slightest x-ray radiation from the depths of space. The study showed that in the galaxies of the red Nuggets cluster, star formation slowed down due to the fact that there are many massive black holes. The stars were not born, but the black holes became more and more massive. For the first time, the red nuggets-like galaxies were discovered by the Hubble telescope, which he found at a great distance from the Earth. The galaxies were already at a time when the Big Bang Universe was only about 4 billion years old. All we see now is now just relic radiation from massive star clusters in the past. On the outskirts of the Universe there are now large elliptical galaxies, and scientists tend to think that they are what the result was from the nuggets of galaxies simply huge mass. Over 14 billion years, many massive galaxies have merged with their own kind and have disappeared, but not all of them. Some stayed a long time in a closed jar and a little with someone all the time interacted. These untouched relics are exactly what scientists are looking for and observing using NASA`s Chandra telescope. The field of study is large, and you can see a black hole, and the stars, which are not touched by anyone huge time, which were in isolation for a long, long time.
The last direction, which was investigated using the telescope Chandra is a gas cloud, it is a highly hot gas in the Central region of the isolated red nugget. Two objects with approximately identical parameters are the MRK 1216 and PGC 032873cluster. One cluster is 295 million and the other is 344 million light years away from Earth. These two objects contain areas of red-hot gas, as it were in the primary red nuggets, but at the same time they are much closer and easier to observe. The hot gas glows in the x-ray range. This heated gas is exposed to massive black holes and can be seen from the radiation emitted.
The primary analysis showed that this pair of galaxies did not interact with anyone in the history of their development, they remained the same for 13 billion years. Scientists on the analysis realized that black holes, large black holes can really slow down the formation of stars in the galaxy, if they actively devour building material throughout the district.
Not all the matter in the form of a heated plasma falls on a black hole, something is thrown out by a black hole with great speed into the outer space. Scientists just tend to believe that not only the absorption of gases in the galaxy, but also the jet with high speed from the black holes interfere with star formation. Jets of hot gas into the outer space prevent the heated interstellar gas from cooling in the galaxy itself, which directly interferes with the active stellar process.
A jet of hot gas from the side of a massive black hole in the galaxy MRK 1216 on a lot hotter than conventional interstellar gas, this is seen in the pictures and all this is the effects of the Black Hole. At some point, this flow even inflates the gases, which attracts a black hole from the outer regions, but then everything subsides and balance comes. Beyond this limit (astronomers call it the Eddington limit) the gas flow has no effect on the gas nebula in the direction of motion, because the movement is in fact not. This is the process of suppression of active star formation, special black holes, over massive objects are to blame.
