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.

‘My power is really low’: NASA’s Mars Insight rover prepares to launch from the Red Planet

Published

NASA Lander InSight He has delivered what may be his last message from Mars as he embarks on a historic mission to uncover the secrets of the Red Planet’s interior.

In November, the space agency warned that the probe could be running out of time as dust continued to condense and stifle InSight’s power.

“Spacecraft power generation continues to decline as windblown dust accumulates on solar panels,” NASA said in a statement. Update November 2. “The end is expected to come in the coming weeks.”

message shared NASA The InSight Twitter account tweeted on Monday: “My power is very low so this might be the last photo I can upload. Don’t worry about me: my time here has been productive and uneventful. If I can keep talking to my mission team, I will—but I will.” Subscribe here soon. Thank you for staying with me.”

A geologist robot armed with a hammer and a seismograph first reached the barren expanse of Elysium Planitia in November 2018.

Since then, she has carried out geological excavations, taking the first measurements of earthquakes with a high-tech seismometer placed right on the surface of Mars.

Last month, the solar-powered car released an update to remind us of its time in space.

“I was lucky to live on two planets. Four years ago I made it safely to the second one, much to the joy of my family at first. Thanks to my team for taking me on this journey of discovery. I hope I can be proud of you.”

According to the published mission, Insight has measured more than 1,300 seismic events since it was published, and more than 50 of them had signals clear enough for the team to extract information about their location on Mars. Results.

The probe’s data also provided detailed information about Mars’ interior, liquid core, surprisingly variable remnants beneath the surface of an extinct magnetic field, climate and seismic activity.

old for Its launch in 2018NASA Chief Scientist Jim Green said the mission was “fundamental to understanding the origins of our solar system and how it became what it is today.”

NASA will not declare the mission complete until Insight confirms the arrival of two spacecraft orbiting Mars that are relaying their information back to Earth.

In 2018, the veteran rover announced the capabilities end of his 15 year stay Sending an incomplete photo of the Valley of Perseverance.

A severe dust storm darkened the sky around the solar-powered rover, shattering the sun and leaving behind a dark image with white spots due to camera noise. The transmission is interrupted before the complete image can be transmitted.
