Fig. 4.


1D profiles of the 3D modeled Lyα distribution decomposed into central (orange lines) and extended (blue lines) components (see Sect. 4.1 and Eq. (3)). These represent the 19 galaxies for which the S/N in the core and halo components is higher than 6. The MUSE identifier are indicated in each panel. The colored labels correspond to the S/N >  10 objects where the same color coding as in Fig. 3 is used. The total spectra of the modeled Lyα emission are shown in purple. For comparison, the observed Lyα lines and their 1σ errors (see Sect. 4.1.2) are overplotted in black and grey respectively. The vertical dotted black lines delimit the spectral window used for the fit (see Sect. 4.1.2). The best-fit line parameters (halo/core FWHM and peak separation) are indicated in km s−1 (blue, orange and black, respectively) in each panel.
