Search for TeV emission from the Fermi Bubbles at low Galactic latitudes with H.E.S.S. inner Galaxy survey observations

Understand

The Fermi Bubbles were discovered about a decade ago in the {\it Fermi}-LAT data as a double-lobe structure extending up to 55 deg.

• in Galactic latitudes above and below the Galactic Center.
• At the moment their origin is still unknown.
• The H.E.S.S.
