237 Lyman-alpha spectra of MUSE-Wide survey

J/A+A/606/A12) to a suite of radiative transfer simulations consisting of a central luminous source within a concentric, moving shell of neutral gas, and dust. This six parameter shell-model has been used numerously in previous studies, however, on significantly smaller data-sets.

We find that the shell-model can reproduce the observed spectral shape very well - better than the also common 'Gaussian-minus-Gaussian' model which we also fitted to the dataset. Specifically, we find that ~94% of the fits possess a goodness-of-fit value of p(chi^2^)>0.1. The large number of spectra allows us to robustly characterize the shell-model parameter range, and consequently, the spectral shapes typical for realistic spectra.
