Energy injection comma soft X-rays and Lyman alpha escape in local starburst galaxies

We propose to observe the Xray properties of a wellstudied sample of localstarbursts with substantial HST observational investment to understand the Lymanalpha (Lya) emission. It has been observed that outflows and turbulence areneeded for Lya photons to escape from galaxies. The mechanical energy (E_k)injected by supernovae and stellar winds into the interstellar medium may end upprovoking those effects, and soft Xray emission. Thus, we expect intrinsicrelations between Lya escape, and quantities like, e.g., the fraction of E_k notdevoted to Xrays, and N(H I), which determines the optical depth for Lya. Thisstudy will thus provide new insights into the details of Lya escape in galaxies,and investigate the link between energy injection into the ISM and Lya emission. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
