Modelling neutral hydrogen discs of spiral galaxies
, 2002 We present an analytical model of a neutral hydrogen disc in a spiral galaxy. The gas disc of the spiral galaxy is assumed to have an exponential surface density profile and to be ionized by the cosmic ultraviolet background. To compare with observations,

, 1995 This thesis deals with surface photometry of face-on spiral galaxies in a statistical way, using both single passband as well as color information of a large sample of galaxies. In this chapter I first discuss galaxy formation and evolution models and the role that photometry plays in testing these models.
