Bubbles and Diffuse X-ray Emission

• Applicants: Dr. Michael Freyberg; Professorin Dr. Manami Sasaki
• Subject Area: Astrophysics and Astronomy
• Term: since 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 414059771

In the first funding period of the Research Unit FOR 2990 we have studied the emission of the diffuse X-ray background observed with eROSITA including the emission from the Local Hot Bubble, the Galactic X-ray ridge, and the very nearby supernova remnants. As the diffuse X-ray emission observed with eROSITA is better understood, we will now extend our studies to that of the diffuse emission from hot interstellar plasma in Galactic superbubbles and in the entire interstellar medium in the Magellanic Clouds. It will allow us to obtain a better understanding of the energy sources and budget, chemical abundances, properties of the plasma, 3-D structure, and the interaction between the hot and the colder phases in the ISM.
