Modelling Mrk 1044’s UV spectrum in the Ly-α window. We use a multi-Gaussian model for the Ly-α emission (blue), and the absorbing systems (orange). The best-fit model (red line) reproduces the spectrum (black line) well in the selected wavelength range. Since the Ly-α systems L1 and L2 are accompanied by high metallicity absorption lines at the same velocity (Fields et al. 2005), the absorbing clouds must be local to the galaxy.
