H I global scaling relations in the WISE-WHISP survey

We present the global scaling relations between the neutral atomic hydrogen gas, the stellar disc, and the star-forming disc in a sample of 228 nearby galaxies that are both spatially and spectrally resolved in H I line emission. We have used H I data from the Westerbork survey of H I in Irregular and Spiral galaxies (WHISP) and Mid-Infrared (3.4 μm, 11.6 μm) data from the Wide-field Infrared Survey Explorer (WISE) survey, combining two data sets that are well-suited to such a study in terms of uniformity, resolution, and sensitivity. We utilize a novel method of deriving scaling relations for quantities enclosed within the stellar disc rather than integrating over the H I disc and find the global scaling relations to be tighter when defined for enclosed quantities. We also present new H I intensity maps for the WHISP survey derived using a robust noise rejection technique along with corresponding velocity fields.
