Arp 65. Top: integrated H i intensity contours (white) on SDSS r-band image. The blue contours are FUV from GALEX. The H i column density levels are 10²⁰ cm^-2× (0.6, 1.2, 1.8, 2.9, 4.7, 5.9, 7.2). Middle left: the H i velocity field for NGC 90, in colour. The black contour shows the GALEX FUV extent NGC 90. The red contour is the H i 0.6 × 10²⁰ cm^-2 contour from the top panel. Middle right: H i spectra for NGC 90: GMRT (black) and single dish (blue) from Springob et al. (2005). NGC 93: single dish spectrum (red) Springob et al. (2005) spectrum for NGC 93. The optical velocities of NGC 90 and NGC 93 are marked with dashed lines. Bottom left: velocity field of the low-velocity component, overlaid with of the total intensity contours of the high-velocity component (blue) and FUV contours (black) define the edge of the galaxy. Bottom right: high-resolution H i intensity contours (black) overlaid on low-resolution H i intensity contours (white) and SDSS r-band image. The low-resolution contours are same as the top panel. The high-resolution contours are 10²⁰ cm^-2 × (1.5,4.6,8.3). For each of the maps the beam size is shown by a black ellipse at bottom of each map.
