EW CoG and spectra of the simulations with continuum pumping. Left: Median cumulative EW in rest-frame as a function or R. The blue and red solid lines (shades) indicate the EW of Si II* λ1533 emission and Si IIλ1527 absorption lines (their 1σ uncertainties) with MUSE PSF convolution, respectively. The cyan and magenta dashed lines (shades) show the intrinsic EW of Si II* λ1533 emission and the Si IIλ1527 absorption lines (their 1σ uncertainties). Middle: Median spectrum extracted from the intrinsic mock cube with a 1.2 kpc aperture (galaxy scale) shown by the black line. The cyan and magenta lines show the wavelength of Si II* λ1533 emission and Si IIλ1527 absorption lines, respectively. Right: Median spectrum extracted from the intrinsic mock cube with a 19 kpc aperture (CGM scale). The EWs of the Si II* λ1533 emission and Si IIλ1527 absorption are consistent on a CGM scale for both intrinsic cubes and PSF-convolved cubes, which are also seen on the mock spectra.
