Astronomers have discovered new properties of the giant lobes of gas called eRosita bubbles that extend far out from the center of our galaxy.
, which, despite possessing a similar shape, are half the size of eRosita bubbles and are also less energetic than their larger counterparts.
These structures extend through the gas that surrounds our galaxy, known as the circumgalactic medium. Astronomers hope that the study of such bubbles sheds light on the process of"Our goal was really to learn more about the circumgalactic medium, a place very important in understanding how our galaxy formed and evolved," research lead author Anjali Gupta, a professor of astronomy of Columbus State Community College in Ohio,.
While scientists had previously assumed that galactic bubbles are heated by shocks of gas pushed out from the Milky Way, Gupta and her team found, surprisingly, that the temperature of the gas within the bubbles is similar to the temperature of the gas outside them. The astronomers found that the eRosita bubbles are bright not because of their temperature but instead because they are filled with extremely dense gas.
Gupta and her colleagues reached their conclusion by examining 230 observations of eRosita bubbles made between 2005 and 2014. These observations characterized emissions from low-density gas from the bubbles and the hot gases around them.
