A black hole launches a jet of matter into a neighboring galaxy



A black hole launches a jet of matter into a neighboring galaxy
In recent months, astrophysicists have announced the discovery of the most powerful gamma-ray burst ever recorded, caused by the formation of a black hole.

according to one published article October 12 in the magazine Monthly Notices of Letters from the Royal Astronomical Societya group of astronomers recently discovered with the help of other scientists the only black hole in a galaxy about a billion light-years awaya which launches a relativistic jet into another galaxy. The investigation was carried out by a team led by Ananda Hotaresearcher UM-DAE Center of Excellence in Basic Sciences.

This scientist was joined researchers do Indian Institute of Astrophysicsfrom the laboratory of the Sorbonne University for Radiation and Matter Research in Astrophysics and Atmosphere (LERMA)do Arecibo Observatorydo Amity Institute of Applied Sciencesdo Tapar Institute of Engineering and Technologyand cooperation [email protected] Citizen Science.

different galaxies

Usually galaxies are divided into three main classes based on size, shape and composition. First, there is ellipticalwhich represent about a third of all galaxies in the universewhich have a round or even rather elongated shape.

then there is spiral galaxies, which are distinguished by their characteristic spiral arms and appear as flat disks with large yellowish tubercles in the center. Finally, there is irregular galaxieswhich are neither elliptical nor spiral and were more common in the early universe.

When it comes to elliptical galaxies, astronomers have noticed that the formation of new stars is very rare and seem to have largely ceased billions of years ago.

elliptical galaxies
About a third of galaxies are elliptical. It is located 2.9 million light-years from Earth, in the constellation Andromeda.

Although the reason for this remains a mystery, current research suggests that the presence of supermassive black holes may be responsible. These “monstrous black holes” cause the centers of massive galaxies to become Active Galactic Nuclei (AGN), where the core is more energetic than all the stars in the disk combined.

In many cases AGN also have massive jets that erupt from their poles, which accelerate gas and dust to relativistic speeds (close to the speed of light).

it is believed that ejection of this material towards other galaxies depletes elliptical galaxies with cold gas and dustwhich would otherwise be fuel for star formation.

Another mystery that astronomers face is how these Jets powered by AGN combine gas from merging galaxies, generating positive feedback. This temporarily leads to an increase in star formation, followed by negative feedback and a decrease in star formation.

To solve this final riddle, Hota and her colleagues observed an elliptical galaxy located about 1 billion light-years from Earth.. However, when Hoth’s team looked at it again through the Giant Wave Radio Telescope (GMRT) in India, they noticed that RAD12 seemed to eject matter from only one pole.

Unlike other jets, which eject matter in pairs and in opposite directions, It turned out that RAD12 ejects matter only towards the neighboring galaxy.or RAD12-B.

supermassive active black hole
Their observations also revealed a plume of young plasma that is conical on the stem and exhales, becoming mushroom-shaped at the end. The yellow details represent galaxies, the largest of which are RAD12 (left) and RAD12-B (right), and the plasma plume is shown in red.

The complete structure extends to 440 thousand light years and much larger than the host galaxy itself. This is the first time the jet has collided with a large galaxy such as RAD12-B.

“We are thrilled to have discovered a rare system that helps us understand the feedback of radio jets from supermassive black holes on the star formation of galaxies during mergers.” says a recent press release from the Royal Astronomical Society (RAS) of Hoth.

GMRT observations and data from several other telescopes strongly suggest that a radio jet in RAD12 is colliding with a companion galaxy. Thanks to the observations of Hota and her team, Astronomers are now one step closer to understanding the impact of such interactions on elliptical galaxies..

Your findings may lead to new insight into how star formation stops in elliptical galaxies, unraveling a long-standing mystery of galactic evolution. This is also proof type of research that is possible currently through collaboration between citizen scientists and astronomers.

CD Projekt Red Wants More Releases Like Cyberpunk Edgerunners



Imagem de: CD Projekt Red quer mais lançamentos como Cyberpunk Edgerunners

after one extremely difficult startCD Projekt Red looks ok now satisfied with the results Cyberpunk 2077, especially after the release of the anime based on the series, released by Netflix. So much so that the producer intends to repeat the feat with more transmedia releases in future. Information taken from Video Games Chronicle.

This intention of the Polish company was disclosed this Monday (28) during the last meeting regarding its financial report. During the conversation it was commented how the success of Netflix animation helped boost game sales.

Launched in September Cyberpunk Edgerunners (Cyberpunk: The Expendables in Brazil) is considered the story intertwines with the game Cyberpunk 2077, which was a huge success for both the streaming platform and the Polish developer. Furthermore, animated series revived public interest in the gamewhich no longer suffered from the myriad problems revealed in its release.

Throughout the meeting, CD Projekt Red management was asked about the possibility of a second season of the popular anime🇧🇷 “We are not confirming any concrete plans for the second season of the series. Edgerunners and nothing special,” explained Michal Nowakowski, senior vice president of business development at the production company, before moving on to the interesting part of the comment.

We want to do more in the transmedia spacewhether it’s linear visual animation or live actors, and those plans haven’t changed,” Nowakowski added. “When we’re ready, you expect to see more announcements from us in this regard“, he concluded.

Taking into account not only Edgerunnerswhich revived interest in Cyberpunk 2077 e led the company to record revenue for the periodbut also games and cartoons Witcher (also on Netflix), it’s to be expected that CD Projekt Red really intends to continue with this strategy.

Producer Rockstar said that he did not believe in the success of GTA



Producer Rockstar said that he did not believe in the success of GTA

The franchise turned 25 last Monday (28)

One of the premier franchises in the history of the gaming industry, Grand Theft Auto (GTA) has not always been unanimous among game makers. In an interview given to BBC 5 to talk about the show’s 25-year history, Colin Macdonald revealed that Rockstar did not believe that the title would become and achieve such success as it is today.

GTA 2 producer McDonald says that many employees and producers working for the company at the time pointed out that the game was on the list of the most discredited games. At the time, Rockstar was working on seven different projects, and Grand Theft Auto was considered by many to be the least successful.

“Least likely to succeed, I called Grand Theft Auto. This is because in May the direction of the game was unclear. It had a lot of bugs that meant you couldn’t play for a few minutes without everything crashing,” Colin McDonald said during an interview, recalling the Rockstar days.

Bugs and problems in GTA development

All of these issues, in addition to the development he described as “problematic,” led virtually no one at Rockstar to believe in the success that the game would become. However, as development progressed, the game began to win favor with the team, who were itching to think of a sequel.

“GTA went through many different iterations and was quite a problematic development. Most of the time it was in production, it failed. By the time I got in, she was almost done and the team was very happy. They were excited to sit down, plan the right sequence, redo what they didn’t like and look forward to seeing where else they could go.”

Twenty-five years after the release of the first game in the franchise, GTA has become one of the biggest hits in the gaming industry. Having one of the best-selling games in history in GTA 5, he saw the latest title as a recipe for success. He single-handedly managed to raise over $1 billion for Rockstar. The cost corresponds to approximately 5.3 billion reais at the current exchange rate.
