Abstract / Description:Edge-on spiral galaxies offer a unique perspective on disks. One can accurately determine the height distribution of stars and interstellar medium (ISM) and the line-of-sight integration allows for the study of faint structures. The Spitzer/IRAC camera is an ideal instrument to study both the ISM and stellar structure in nearby galaxies; two of its channels trace the old stellar disk with little extinction and the 8 mum channel is dominated by the smallest dust grains (polycyclic aromatic hydrocarbons, PAHs). te{Dalcanton04} probed the link between the appearance of dust lanes and the disk stability. In a sample of bulge-less disks they show how in massive disks the ISM collapses into the characteristic thin dust lane. Less massive disks are gravitationally stable and their dust morphology is fractured. The transition occurs at 120 km s^{-1} for bulgeless disks. Here we report on our results of our Spitzer/IRAC survey of nearby edge-on spirals and its first results on the NIR Tully-Fisher relation, and ISM disk stability.
