• Most massive galaxies up to 10 12 Msun in stars <br />
– Typically found at the center of groups/clusters <br />
– Hot X-‐ray emivng halo <br />
– Highly clustered <br />
– Pressure supported (blackboard) <br />
– Devaucouleurs profiles (blackboard) <br />
• There are smaller version, down to dwarfs <br />
– Younger stellar ages <br />
– Increased rota^onal support <br />
– Seric profiles with n-‐>1 (blackboard)
