Velocity-resolved spectra toward the CO globules in Orion’s Veil. Each panel shows the [C II] 158 μm line (colored in gray), ¹²CO J = 2–1 (dark blue), ¹³CO J = 2–1 (cyan), and C¹⁸O J = 2–1 (red) lines toward the emission peak of each globule (labeled by symbol # as in Figs. 3 and 4). The x-axis represents the LSR velocity in km s⁻¹. The vertical red dotted line marks the approximate velocity of the emission produced by OMC and associated star-forming molecular cloud located behind the Veil. All panels show emission features at velocities blueshifted from OMC. Globules #1, #2, and #3 represent the first detection of quiescent CO emission structures at negative LSR velocities in Orion.
