Spitzer IRAC 3.6 μ image (flux unit (MJy sr−1)) of Messier 95 with the black contour demarcating stellar bar detected with a length ∼4.2 kpc. The HI contour (black colour) from THINGS (levels −0.66,20.22,41.10,61.99,82.87 in flux unit (Jy beam−1 s−1)) and the CO contour (yellow colour) from HERACLES (levels −1.65, 2.27 in flux unit (K Km s−1)) are overlaid. There is an offset between the HI and CO emission peak at the centre of the galaxy. The colour scale is adjusted such that the stellar bar feature is prominently seen in the IRAC 3.6 μ image.
