Presentation transcript:

Feedback from Massive Stellar Clusters in Starbursts (Poster 7) Andrea M. Gilbert (MPE) & James R. Graham (UCB) SSCs dominate star formation and feedback in starbursts. They are individual cells of superwind engines. Youngest SSCs in the Antennae drive supersonic mass-loaded outflows that may be momentum-driven by radiation pressure on dust grains. Energy budget problem: Small fraction of stellar input energy is observed. Cluster winds have low terminal velocities, but they are powerful enough to blow out of disks. SSCs can power diffuse X-ray emission on kpc scales.
