Are galaxy groups metal-poor

Metals, through the emission of spectral lines, play a fundamental role in thecooling processes at work in the ICM. But when, where, and how these metalsformed and were distributed through the cluster volume is still under debate.Detailed measurements out to large radii will improve our knowledge of the metalenrichment in galaxy groups and clusters, by directly exploring most of thesystem.s volume. While in recent years metallicity measurements to R500 havebeen done for a sizable number of galaxy clusters, we are still missingsystematic measurements at such radii for galaxy groups. We repropose a pilotsample of four galaxy groups that were awarded C time, one of which has nowbeen partially observed (IC1262), to derive the abundance profiles to R500. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
