We present a two-dimensional analysis of the bright nearby galaxy group NGC5044 using the currently available Chandra and XMM data. In the inner 10 kpc apair of cavities are evident together with a set of bright X-ray filaments. Ifthe cavities are interpreted as gas displaced by relativistic plasma inflatedby an AGN, even in the absence of extended 1.4 GHz emission, this would beconsistent with a recent outburst as also indicated by the extent of dust andH_alpha emission. The soft X-ray filaments coincident with H_alpha and dustemission are cooler than the ones which do not correlate with optical andinfrared emission. We suggest that dust-aided cooling contributes to form warm(T =10^4 K) gas, emitting H_alpha radiation. At 31 kpc and 67 kpc a pair ofcold fronts are present, indicative of sloshing due to a dynamical perturbationcaused by accretion of a less massive group, also suggested by the peculiarvelocity of the brightest galaxy NGC 5044 with respect to the mean groupvelocity.
