Info

What is a Galaxy Group? (a personal definition) • A dark matter halo with >2 galaxies and σ gal ~ σ stars (σ~150-400 km/sec), i.e. ~ M~ 10 13 - 10 14 M • Optical: 3-50 galaxies, d~Mpc, L~ 10 11 - 10 12 L • X-rays: kT
Sub-types of interest X-ray: NASA/CXC/INAF- Brera/G.Trinchieri et al.; • Compact (HCG) -- short dynamical time • Fossil -- light dominated by single elliptical (complete merging, early formation ) • Cluster subgroup (e.g., NGC 4472) NASA/CfA/J. Vrtilek et al. Scale Khosroshahi et al. 2007
