Star formation plays a crucial role in understanding the chemical and thermodynamical evolution of the IGM. In galaxies undergoing intense star formation, outflows powered by supernovae and stellar winds expel metal enriched material and ionizing radiation into the IGM. The higher star formation rates at earlier epochs imply that galactic outflows play an even more important in high redshift galaxies such as the well studied Lyman Break Galaxies (LBGs). The interacting/merging galaxy VV 114 has been identified through SDSS and GALAX observations as a local LBG analog, perfect for studying the outflows spectroscopically in the FUV. Our analysis of the FUSE observations of VV 114 show strong and broad interstellar absorption lines that are typical of LBG galactic winds. We present the results of our analysis of the ISM absorption lines observed in the FUV of VV 114.
