Metals in in galaxy groups\: the case of the outskirts of NGC 5044

We propose to complete the mosaic of XMM observations in the nearby brightgalaxy group NGC 5044. The two previous offset observations in the South and inthe West showed a very low iron abundance, 4 times less than that predicted bystandard SNcc and SNIa enrichment models for rich clusters. The new XMMobservations in the North and East will complete the mosaic and may point to anhigher then expected uplifting of enriched gas by sloshing, advancing ourunderstanding of metal enrichment in groups. If instead the low abundance willbe confirmed it will be a challenge to current enrichment scenarios. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
