Galactic storm discovered at ALMA observatory | Digital Trends Spanish

At the ALMA observatory, an important astronomical find: A gigantic galactic windstorm was detected, generated by a supermassive black hole.

This phenomenon is the first of its kind that has been observed to date, although it did not occur recently (not at least in human terms), but more than 13.1 billion years ago. And it is the oldest galactic wind detected; the former dates from 13,000 million years ago.

The discovery of this galactic wind raises several questions for researchers who have studied it. Takuma Izumi, of the National Astronomical Observatory of Japan, assures that it is important to ask when the Galactic winds first appeared, because it is related to “an important astronomical problem: how is it that galaxies and supermassive black holes evolved together”.

For the case of this discovery, the latter is relevant because in the galaxy in which the galactic wind was detected, both the mass of the black hole and the center of the galaxy itself are similar. A galactic wind allows two entities of similar mass but different sizes to co-evolve together.

Analysis of the data obtained by ALMA revealed that some gases in the galaxy J1243 + 0100 were moving at a speed of 500 kilometers per second, which has enough energy to move star particles and prevent them from forming.

The Subaru telescope in Japan detected more than 100 galaxies at the center of which is a supermassive hole. Then, the next step is to analyze these galaxies using the ALMA telescopes in Chile; this is how this galactic storm was detected and so it is also expected to find others that if this type of co-evolution between galaxies and black holes “means a more or less accurate portrait” of the state of the universe 13,000 million years ago.
