The X-ray view of the Galactic outflow

Mercoledì 15 settembre alle ore 15:00,  Gabriele Ponti dell'INAF, Osservatorio Astronomico di Brera, terrà il Colloquio di Fisica dal titolo "The X-ray view of the Galactic outflow", on line.

Outflows from Active Galactic Nuclei and starburst galaxies are known to play a critical role in the formation and evolution of structures in the Universe. However, the role of such outflows in normal galaxies is still highly debated. 
Being located at only ~8 kpc from us, the center of our Galaxy provides us with the unique opportunity to study the physics occurring in the core of normal galaxies at very high spatial resolution. Thanks to its penetrating power, the X-ray band is particularly suited for studies of the Galactic center, allowing us to have a direct view of the central heart of the Milky Way. 
I will review the evidence which probe the presence of an outflow from the center of the Milky Way. 
In particular, I will report recent results demonstrating the presence of an outflow of hot plasma, connecting the central parsecs around the central supermassive black hole (Sgr A*) with the base of the Galactic halo. 
Additionally, I will discuss the discovery of the eROSITA bubbles as well as the potential provided by eROSITA to improve our understanding of the hot phase of the Milky Way.
