Zooms of the molecular surface density, peak temperature, and line width towards the galaxy center. The images have been deprojected from the galaxy inclination on the plane of sky, and then converted to kpc using a distance of 3.45 Mpc. The yellow lines show our spiral mask, while the red and white ellipses delimit the extent of the bar and center environment, respectively (see Appendix B.3 for the definition of these environment).
