We present a robust representation of the chemical and thermal structure inthe galaxy group NGC 5813 using archival, deep X-ray observations, andemploying a multi-temperature spectral model based on up to date atomic lineemission databases. The selection of our target is motivated by the fact thatNGC 5813 has a very relaxed morphology, making it a promising candidate for thestudy of the AGN feedback's influence in the intra-group medium (IGrM). Ourresults showcase a prominent, extended distribution of cool gas along thegroup's NE-SW direction, correlating with the direction along which thesupermassive black hole in the group's central galaxy is known to interact withthe IGrM. Our analysis indicates gas being uplifted from the group's centre asthe probable origin of the cool gas, although alternative scenarios, such asin-situ cooling can not be explicitly ruled out. Regarding the chemicalstructure of the IGrM, and unlike previous findings in massive clusters, wefind no evidence for recent metal transport by jets/lobes from the central AGN.Instead, elemental abundances remain near Solar on average across the group.The distribution of elements appears to be independent of galactocentricradius, azimuth and the thermodynamics of the gas, suggesting that the IGrM hasbeen efficiently mixed. The large scale uniformity of the abundancedistribution implies the presence of complex dynamical processes in NGC 5813,despite its overall relaxed morphology. Past events of extreme AGN feedback orsloshing could be the primary mechanisms behind this.
