Abstract
We present HST/STIS spectroscopy for one slit position crossing the starburst core of M82, sampling both clusters and ionized gas at optical wavelengths. The spectra have a spatial resolution of 2 pc at the distance of M82, allowing us to probe the conditions within a starburst environment in unprecedented detail. We find that the ionized gas has high turbulent and thermal pressures (P/κ ∼ 107), reflecting the intense energy input from supernovae concentrated in super star clusters. The data also provide new insights into young clusters and their immediate environments. We identify a 6–7 Myr old cluster, M82-A1, which is still embedded in a compact Hii region.
