The Intricate Nature of Galactic Bubbles in the Milky Way.

A new study published in Nature Astronomy has revealed that the eRosita bubbles, giant structures of high-energy gas extending above and below the Milky Way galaxy’s center, are more complex and not hotter than surrounding areas, contrary to previous assumptions. The study suggests that the bubbles originate from nuclear star-forming activity rather than a supermassive black hole. The researchers used observations made by the Suzaku satellite to analyze the properties of these bubbles and hope to use new data from other upcoming space missions to continue characterizing them.

The Complexity of the Milky Way's Cosmic Bubbles

The giant bubbles of hot gas blown out from the center of the Milky Way galaxy, known as eRosita bubbles, are far more complex than previously believed, according to a new study. The study examined the thermal and chemical properties of these features, revealing hitherto undiscovered properties in their shells. Scientists had previously assumed that galactic bubbles are heated by shocks of gas pushed out from the Milky Way, but the temperature of the gas within the bubbles is similar to the temperature of the gas outside them. The eRosita bubbles are bright not because of their temperature but instead because they are filled with extremely dense gas.

Unraveling the Complexity of Giant Bubbles Around the Milky Way

The eROSITA bubbles, a pair of huge, symmetrical blobs of gas extending high above and below the Milky Way's galactic plane, have been found to be more complex than previously thought. Data from the Suzaku satellite suggests that the X-ray glow of the bubbles is due to the higher density of the gas inside them, rather than their assumed higher temperature. The bubbles are thought to have been formed by nuclear star formation, rather than black hole activity, and are connected to smaller but similarly shaped blobs of gas called Fermi bubbles. Further research is needed to better understand the formation of these structures.
