Beginning of ReadMe : J/ApJ/688/237 Disk corrugations in IC 2233 (Matthews+, 2008) ================================================================================ Corrugations in the disk of the edge-on spiral galaxy IC 2233. Matthews L.D., Uson J.M. <Astrophys. J., 688, 237-244 (2008)> =2008ApJ...688..237M ================================================================================ ADC_Keywords: Galaxies, IR ; Ultraviolet ; H I data ; Interstellar medium Keywords: galaxies: individual (IC 2233) - galaxies: spiral - galaxies: structure - instabilities - ISM: structure Abstract: We recently reported the discovery of a regular corrugation pattern in the HI disk of the isolated, edge-on spiral galaxy IC 2233. Here we present measurements of the vertical structure of this galaxy at several additional wavelengths, ranging from the far-ultraviolet to the far-infrared. We find that undular patterns with amplitude < 5"(< 250pc) are visible in a variety of Population I tracers in IC 2233, including the young to intermediate-age stars, the HII regions, and the dust. However, the vertical excursions become less pronounced in the older stellar populations traced by the mid-infrared light. This suggests that the process leading to the vertical displacements may be linked with the regulation of star formation in the galaxy. We have also identified a relationship between the locations of the density corrugations and small-amplitude (< 5km/s) velocity undulations in the HI rotation curve. We are able to exclude several possible mechanisms for the origin of the observed corrugations, including tidal interaction from a companion, Parker instabilities, or a galactic bore. Global gravitational instabilities appear to be the most likely explanation, although local perturbations may also be important.
