🌌🛰️🔥 A new study combining Chandra X-ray and GMRT radio data reveals that the nearby galaxy group IC 1262 is being chemically reshaped by sloshing cold fronts: gas inside the fronts is 45% more metal-enriched than the gas just outside, and a sharp metallicity drop traces the path of an eastern front sweeping through the intragroup medium. The work pinpoints sloshing as a dominant mechanism for redistributing heavy elements in galaxy groups.
