Title of your presentation : Absorption Features of high-redshift galactic winds

The environment of high-redshift galaxies is characterized by both wind-driven outflowing gas and gravitationally infalling streams. To investigate such galaxy-IGM interplay we have generated synthetic optical absorption line spectra piercing the volume surrounding Galaxies selected in a z~3 output from a SPH simulation. Distributions for several observable species (HI, CIII, CIV, SiII, SiIII, SiIV, OVI, OVII, and OVIII) have been derived by post-processing the simulation outputs. We will discuss these results in light of the recent observational data addressing the feasibility of observing galactic winds bubbles.
