Surface brightness maps for three UV emission lines for the Blizzard halo, shown edge-on. Each column corresponds to a different spatial resolution: 0.18, 1, 3, and 6 kpc. These correspond at z = 0.5 (z = 0, 10 Mpc) to ∼ 0.04 (5.6), 0.16 (21), 0.5 (62), and 1 (123) arcsec, respectively. The galactic disk has been removed to isolate CGM emission. The colormap represents surface brightness in units of photons s⁻¹ cm⁻² sr⁻¹, with grayscale indicating regions below a representative instrument sensitivity threshold. Colored regions are potentially detectable by instruments with corresponding sensitivity. For reference, at z = 0.5, 6 kpc subtends ∼1″, similar to the limits of seeing-limited ground-based observations, while a space-based telescope or AO-assisted ground-based telescope could reach ∼0﹩\mathop{.}\limits^{\unicode{x02033}}﹩1, or ≲ 1 kpc spatial resolution.
