Stunning new map of the X-ray universe

Dec 1,2023 7:41 pm

See, the hot, energetic universe.

A German-Russian space telescope just acquired a breakthrough map of the sky, the traces of the sky in x-rays.

The Image draws a lot of sharp movement in the Cosmos - instances, where matter is accelerated, heated and crushed.

Feasting Black Holes , exploding stars and burning hot gas.

The data will come from the mounted on Spektr-RG.

This space telescope was In July Last Year and sent to an observing position some 1. 5 million km from earth. Once commissioned and declared fully operational in December, it was to turn slowly and scan the depths of space.

eRosita, the first all-was completed in sky-set of data, shown in the picture above on this page, and, as recently as last week. It's about A Million sources of x-ray detected radiation.

"This is actually pretty much the same number as has been recognized, in the entire history of the X-ray astronomy back 60 years. We have, in fact, the well-known sources doubled in just six months," says Kirpal Nandra , head of the high energy astrophysics group at the Max-Planck-Institute for extraterrestrial physics (MPE) in Garching, Germany.

"The data is really stunning and I think what We Are doing here will revolutionize X-ray astronomy," he told Bbc News .

of The Vela Supernova Remnant is 800 light years from earth

The card is called the Aitoff projection is used, which grabs the sphere of the sky to an ellipse. The tape over the center of the plane of our Milky Way galaxy, with the center of The Galaxy in the center of The Ellipse .

The Image has been encoded to describe color to what's going on. Blues the higher energy X-rays (1-2. 3 kilo electron volts, keV); the green are mid-range (0. 6-1 keV); and red are low energy (0. 3-0. 6 keV).

Much of The Galaxy , the level is dominated by high-energy sources. In part, this is because of the huge amounts of gas and dust is absorbed and filtered from the lower energy of the radiation. Sources are stars with strong magnetic active and extremely hot environments.

The green and yellow tones, featuring a type of fungus feature covers a large swath of the map represent the hot gas within and outside our galaxy. This material prints information about the origin and evolution of the Milky Way .

Some of the larger spots are well-known actors at the sky. The Bright yellow spot above the level on the right-hand side is the remains of a concentration of a supernova - The Wreckage of stars, which exploded and the shock waves of superheated a surrounding cocoon of gas and dust. This particular patch is dominated by the Vela Supernova Remnant . The was an explosion thousands of years Ago , but only 800 light-years away from earth.

Look next to the diffuse Red Glow at The Top and bottom of the card. This is especially X-ray emission of hot gas, even outside of our galaxy. And the white polka dots are, we see, in principle, the signature of super-massive Black Holes . In fact, over 80% of all sources, which is included in the new map the giant Black Holes in the centers of distant galaxies. You pump out X-rays, as their immense gravity pulls on and eviscerates matter.

Some of the super-massive Black Holes that are see an appearance in the card, as The Universe is younger than a billion years old, less than 10% of its current age.

Spektr-RG and his eRosita-instrument plan to collect the seven all-sky surveys over The Next 3. 5 years. This allows The Telescope to remove Refine your data, the artifacts and noise, but also to feel, deep in the Cosmos , and to Pick Up weak sources, otherwise the detection.

A Central aim of the representation of the distribution of the hot X-ray emitting gas, lights up the large Cluster of galaxies.

the astronomers hope that this information can lead to the fact that she's built up some fresh insights into how The Universe and how it has changed over time. It is possible that there may be some clues in this project about the nature of Dark Energy , the mysterious "force" apart appears to be pushing the Cosmos , in ever increasing speed.

"This is The Great price, but it would only be declared at The End of The Mission ," Prof Nandra.

"enables the Eight polls we go really deep into the distant universe. Basically, we try all the clusters of galaxies in The Universe recognize the limit of a certain mass. We have a nice example already - Maybe 10,000. But we hope to at least 100,000 galaxy clusters. "

eRosita is The German element on Spektr-RG. It takes up most of The Room on the spacecraft bus, or chassis. But it sits next to a Russian instrument known as the ART-XC, which is sensitive to higher energies up to 30 keV.

Both eRosita and ART-XC on the use of a cluster of seven tube-shaped mirror modules corral X-ray light down to your sensitive camera Detectors .
