DESCRIPTION:Speakers: Mauro Valli (SISSA)\nThere is a striking evidence fo
 r a roughly spherical-symmetric diffuse gamma-ray signal peaked in the Gal
 actic Center (GC) region\, extended up to several degrees off the GC. \nHe
 re we critically review the main points regarding the derivation of this s
 ignal\, characterized by means of the template-fitting method. In particul
 ar we focus our attention on the usual Inverse Compton (IC) component adop
 ted for the background emission\, finding that it does not provide a reali
 stic description of the complex GC environment. Driven by the evidence of 
 a large gas density in the inner kpc of the Galaxy correlated with an impr
 essive Supernova rate (2 order of magnitude larger than the Galactic avera
 ge)\, and therefore with ongoing CR acceleration\, we are able to show tha
 t no clear evidence of the aforementioned excess comes out when a possibly
  more realistic diffuse CR source term is taken into account.\n\nhttps://i
