Galaxy groups at 0.3 ≤ z ≤ 0.55 - II. Evolution to z ∼ 0
We compare deep Magellan spectroscopy of 26 groups at 0.3 ≤ z ≤ 0.55, selected from the Canadian Network for Observational Cosmology 2 field survey, with a large sample of nearby groups from the 2PIGG catalogue. We find that the fraction of group galaxies with significant [O II]λ3727 emission (≥5 Å)...
