Possible shock drivers overlaid on the L_CO/L_TIR image (Sect. 5.3.4 for details). (1) LMC X-1 and its proposed jet (black cross and arrow; the angle of the jet was estimated by Cooke et al. 2007); (2) SNR J0540.0−6944 (blue circle; the diameter corresponds to the size of ~19 pc measured by Williams et al. 2000); (3) protostellar outflows (red squares; N159W-N and N159W-S); (4) colliding filaments; (5) SGS 19 (purple circle; this HI supergiant shell cataloged by Kim et al. 1999 is only partially shown here); and (6) wind-blown bubble (pink circle; the diameter is ~40 pc, as suggested by Jones et al. 2005). The ALMA CO(2–1) observations on ~1′′ scales where the protostellar outflows and the colliding filaments were identified (Fukui et al. 2015) are shown as the white contours with levels ranging from 10% to 90% of the peak (29 Jy Beam^-1) in 20% steps. The five pixels used in our Meudon PDR modeling (Sect. 5.1.1) are also outlined in green.
