Flows of hot plasma connecting the Milky Way centre to the corona, halo and beyond

Project description

Sensitive X-ray study to reveal hot plasma pouring out from Milky Way centre

In the 1990s, the Roentgen Satellite (ROSAT) telescope performed an all-sky survey in the X-ray band, confirming the existence of the Galactic corona – a hot, ionised, gaseous component found in the interstellar medium (ISM). This is a critical finding, since scientists assume that the growth of galaxies depends on the interplay between the hot plasma and the other phases of the ISM. However, the properties of the hot plasma are unknown outside the solar neighbourhood, because these maps can not track the hot plasma beyond 1 thousand parsecs, in the Galactic plane. The EU-funded Hot Milk project will conduct an X-ray survey that will exceed the sensitivity of current surveys by two orders of magnitude. Its aim is to clearly demonstrate that flows of hot plasma connect the Milky Way centre to the galactic halo.
