Most distant black hole ever: This article explores the topic in depth.
Similarly,
Thanks to the James-Webb space telescope. Similarly, astronomers can now probe a period of the universe which has so far been inaccessible to them. Consequently, And they have already made incredible discoveries there. However, Today, that of the most distant supermassif black hole never observed.
Since its launch in 2021, the James-Webb space telescope (JwstJwst) has already pushed a lot of limits. Furthermore, He discovered an asteroid not even 200 meters in diameter. Consequently, He returned unprecedented details to dust discs surrounding young stars. For example, These discs in which the planets form. Moreover, And potentially appears life.
The JWST also revealed galaxies already as massive as the Milky Way when our universe was not more than 500. Furthermore, million years old. Meanwhile, As well as several black holes among the oldest in the universe! Similarly, Behemoths over a billion times the mass of most distant black hole ever SoleilSoleildetected less than a billion years after the Big BangBig Bang. But also black holes that are always supermassive, but less imposing and older.
Precisely today. astronomersastronomers of the University of Texas (United States) announce that it has identified, thanks to telescopetelescope James-Webb and in the Capers-Lrd-Z9 galaxy, the most distant black hole ever confirmed. A black hole observed when the universe had no more than 500 million years. Or more than 13.3 billion years in the past. A unique opportunity to study the structure and evolution of our universe at this distant time.
A distant black hole revealed by spectroscopy
“Although astronomers have identified some more distant candidatesspecifies Steven Finkelstein. co-author of the article and director of the Cosmic Frontier Center of the University of Texas, in most distant black hole ever a press release, They have not yet found the distinct spectroscopic signature associated with a black hole. »» In theAstrophysical Journalher team explains what she hears there.
To understand. remember that spectroscopy makes it possible to decompose the lightlight in its different wavelengthswavelengths and thus study the characteristics of an astronomical object. However. researchers know that when a gazgaz falls into a black hole, its light is stretched towards the red wavelengths for the part which moves away from us and towards the more blue wavelengths for the one that comes to us. “Few other objects have such a signature. And the galaxy capers-lrd-z9 a »assures Anthony Taylor, astronomer at Cosmic Frontier Center.
Precious information on “small red points” galaxies
This galaxy. the researchers first interested in it as part of a new category of galaxies called “Small red dots”. These galaxies, discovered by the JWST, surprised astronomers. Because they only exist in the first 1.5 billion years of our universe. And that they are very compact, red and shiny. After the amazement phase, the researchers wanted to learn more about their nature and their origin.
What they derive from data concerning Capers-LRD-Z9 is first of all proof that the Supermassive black. holesSupermassive black holes could well be the cause of the brightnessbrightness unexpected “Small red dots”. Their brightness. in fact, is difficult to explain by an abundance of stars at a time in our universe where it is completely improbable. While the black holes shine intensely by compressing and heating the mattermatter that they attract to them.
The presence of a black hole in the heart of Capers-Lrd-Z9 can. moreover, explain the colorcolor Characteristic of galaxies “Small red dots”. A red color that could be due to a thick cloudcloud of gas surrounding the black hole. which shifts the light towards lighter wavelengths.
Finally understand the evolution of supermassive black holes
To return more particularly to the black hole. astronomers of the University of Texas estimate its mass at around 300 million times that of our sun. It’s impressive. A little more when you know that it represents up to half the mass of all the stars in. its galaxy. It’s colossal. Even for a black supermassive hole.
It is also disconcerting because black holes grow in principle by engulfing matter over time. However, this should not most distant black hole ever have had enough time to become so massive so early in the history of our universe. “This strengthens the increasingly numerous evidence that the first black holes have developed much faster than we thoughtestime Steven Finkelstein. Or else, they were at the start much more massive than what our models predict. »» Astronomers may be able to decide thanks to more observations at higher resolutionresolution Using the JWST.
