The Milky Way says the Milky Way has a vacuum

The Milky Way is surrounded by hot gases that constantly deliver matter emitted by birth or dying stars, astronomers say.

This hot galaxy, called the Circum Galactic Medium (CGM), was the incubator for the formation of our galaxy about 10 billion years ago, and may have been the base material that has not been counted since the birth of the universe.

These findings are based on observations made by Holosat to examine X-rays emitted by CGM.

Researchers in Nature Astronomy have concluded that there is a disk-like geometry based on the intensity of X – ray radiation emitted by CGM.

Philip Carrett, a professor of physics and astronomy at the University of Iowa, is the author of the study:

“This suggests that the circalactic medium is involved in star formation, and that we may see gas that previously fell into the Milky Way and helped form stars.

Each galaxy has a CGM, which is crucial for understanding not only how galaxies formed and evolved, but also how the universe evolved from the kernel of helium and hydrogen into a vast universe of stars, planets, comets, and all other celestial bodies. Things.

Launched in May 2018 from the International Space Station, the Holosat minisatellite is the first mini-satellite funded by NASA’s astronomical division.

It was launched about 14 billion years ago to search for atomic debris called baryonic matter, which has been missing since the birth of the universe.

The satellite is being monitored by the CGM of the Milky Way as evidence that residual baryonic matter may have resided there.

The researchers wanted to find out if CGM is an extended halo many times the size of our galaxy – in this case, it could contain the total number of atoms to solve the lost baryon question.

But if it is made mostly of recycled materials, it has a relatively thin, brittle gas layer and no possibility of missing baryonic material.

Prof. Carrett said: “The Milky Way and other galaxies do not seem to be closed systems.

“They actually engage, throwing the material into the CGM and bringing the material back.”

The next step is to combine the halosat data with data from other X-ray observatories to determine if there is an extended halo around the Milky Way and to estimate its size if any.

Researchers say the missing Barion puzzle can be solved.
