Captions for Colour Plates Plate 1 (Fig. 1, Block et al.) Spiral galaxies in the dust penetrated regime are binned according to three quantitative criteria: firstly, Hm, where m is the dominant Fourier harmonic (illustrated here are the two-armed H2 family). Next, follows the dust penetrated pitch angle families 0:, {3 or 'Y (for class 0:, the pitch angles range from r-v 4-15°; for class (3, the deprojected pitch angles range from r-v 15-30°, while open-armed class 'Y spirals have pitch an­ gles ranging between r-v 35- 75°). Finally, we compute the gravitational torque, which is identical to the bar torque in galaxies presenting a bar. Bar torques are not derived from bar ellipticities but exploit the full gravitational potential of the disk within which it is embedded. Note that early type b spirals (NGC 3992, NGC 2543, NGC 7083, NGC 5371 and NGC 1365) are distributed within all three families (0:, {3 and "(). Hubble type and dust penetrated class are uncorrelated. Plate 2 (Buta) An issue of much debate at the Conference, was observational ev­ idence for bar dissolution and bar reformation. Seen here is an HST image of NGC 3081, which might be considered in the category of the bar dissolution. John Kormendy writes: "To me, a weak bar is suggestive evidence for bar suicide. Do we really believe that global disk instabilities or tickling by encounters can make a bar that is a few percent of the disk mass? This is not what happens in simulations. The bars that get made by these processes contain most of the disk mass that is interior to the end of the bar. Would it not be easier to understand the formation of a bar that is a few percent of the disk mass if it formed as a much stronger perturbation and then decayed?" Plate courtesy Ron Buta. Plate 3 (Fig. 7, Beckman et al.) (a) Surface brightness map in Ho: of NGC 1530, from a TAURUS data cube from the 4.2m WHT La Palma. (b) Radial velocity map of ionized gas from the peaks of the Ho: emission lines across the face of the galaxy, using the same data cube. (c) Contours of Ho: surface brightness superposed on a two-dimensional projection of the rotation curve derived from the velocity field shown in (b). (d) Map of the residual, non-circular velocity field, obtained by subtracting off the 850 Colour Plate Captions projected rotation curve in (c) from the complete velocity field in (b). The strong non-circular velocity field aligned with the bar is clearly seen here, as the galaxy inclination causes the flow along one side to be directed towards us, and away from us along the other side of the bar (see text for more details, also see Zurita et al. 2004).

Plate 5 (Fig. 4, Kormendy and Cornell) Nuclear star formation in the unbarred galaxies M51 and NGC 4321 (M100). Dust lanes on the trailing side of the global spiral arms reach in to small radii. As in barred spirals, they are are indicative of gas inflow. Both galaxies have concentrations of star formation near their centers that resemble those in Figure 3. These images are from the Hubble Space Telescope and are reproduced here courtesy of STScl. Plate 6 (Section 5, Fazio et al.) Mosaic of galaxies at infrared wavelengths taken with the IRAC instrument on the Spitzer Space Telescope. Colors are coded as 3.6 (blue), 4.5 (green), and 8.0J,tm (red). The galaxies are arranged ac­ cording to traditional, optical morphological classifications. Starlight appears blue at these mid-infrared wavelengths, while warm dust (emit­ ting in the PAH emission lines) appears red. AGN emission is also red and point-like (e.g., NGC 5548). There is a clear transition from blue, stellar-dominated emission for the early-type galaxies to red, ISM-dominated emission for the late-type galaxies. Plate 7 (Section 5, Fazio et al.) Four galaxies observed with the Spitzer Space Telescope. (Top left): NGC 4203 is a lenticular galaxy, presenting striking rings of dust (coded red) in the central domains. (Top right): Masks of dust are well seen in the edge-on galaxy NGC 5746. (Bottom left): NGC 1961 is a late-type spiral with an unusual morphology. (Bottom right): We finally show the nearby spiral NGC 300. The reader is referred to Fazio et al. for further details. Plate 8 (Fig. 6, Ford et al.) A composite ACS i,z image of the brighter of the two most conspic­ uous sub-clusters in CL0152. The field size is 90" (rv 690 kpc in the Colour Plate Captions 851 rest frame ) Spectroscopically confirmed members are circled (6" diame­ ter; rv 50 kpc in the restframe). There are several thin arcs from lensed background galaxies that are much bluer than the early-type galaxies in the cluster. The lensed galaxy at the center has two components that are mirror images, indicating that the galaxy is very close to a caustic. Plate 9 (Fig. 7, Ford et al.) Star-forming galaxies in CL0152 and morphology of the X-ray emit­ ting gas. Spectroscopically confirmed passive galaxies are circled and galaxies with star formation, as indicated by [OIIj,\3737 emission, are shown with a "star". The latter are typically spirals and late-type galaxies, while the former are mostly E/SOs. The insets show typical morphologies and spectra. The spatial segregation of the star forming later type galaxies is very striking. The Chandra X-ray isophotes (De­ marco et al. 2004; Maughan et al. 2003) are 3, 5, 7, 10,20 and 30 sigma above the background. Plate 10 (Top: Fig. 2, Vlahakis et at.; Bottom: Fig. 1, Zurita et al.)

This stunning image was secured by Sylvie Beland on June 8, 2004 at 5h 53m (EDT). The site was the Observatory of "Centre de la Nature" in Laval, Quebec, Canada. She used a Nikon Coolpix 4300 IS0400 at f/2.8, exposure time 1/2 second. For this image, Beland employed a 25mm Lanthanum eyepiece, a Baader filter and her 8-inch f/5 Newton Dobsonian Telescope.
