Fitting exponential profiles to the bulges of the early-type spiral galaxies from de Jong & van der Kruit (1994) under-estimates their sizes at the 2-3 sigma significance level. Allowing for the range of structural shapes which these bulges possess - through fitting an r1/n profile - the mean effective bulge radius to disk scale-length ratio, re/h

Galaxy redshift surveys from z ˜ 1 to z ˜ 4 providing thousands of identified objects are already available. Only for a small and selected sample of those galaxies, near-infrared (NIR) spectroscopy and emission line studies exist. This is mainly due to the time-consuming work of observing one object at a time. This will change with the advent of

The K-band light-profiles from a sample of roughly 100 disk galaxies have been simultaneously modelled with a seeing convolved Sersic r1/n bulge and an exponential disk. Rather than a constant central disk surface brightness, in the near-infrared, μ0,K is shown to decrease with the logarithm of the disk scale-length (log h) - with a correlation

K-band imaging was carried out on a sample of 57 spiral galaxies to map their stellar backbones, examine the underlying mass distribution across the arm and interarm regions, and perform bulge:disk decomposition. As within the broader aims of the project, which also use B, I, and Hα images, our results will be examined in the light of global
