The distribution of star formation in the central regions of spiral galaxies
Mazzuca, L.M.; Knapen, J.; Regan, M.; Veilleux, S. (American Institute of Physics (AIP), 2005)Nuclear rings are characterized by their high star formation rates, and are believed to be the products of gas inflow towards the inner regions of spiral galaxies. We present first results from a statistical survey of these ... -
Erratum: Structure and star formation in disc galaxies - I : Sample selection and near-infrared imaging
Knapen, J.; de Jong, R.S.; Stedman, S.; Bramich, D.M. (2003) -
Evolution of structure in late-type spiral galaxies I: ionized gas kinematics in NGC 628

The Extended Bar and Grand-Design Spirals in NGC 5248
Jogee, S.; Knapen, J.; Shlosman, I.; Englmaier, P.; Laine, S.; Scoville, N.Z.; Wilson, C.D. (Astronomical Society of the Pacific, 2002)We present a study of the grand-design spiral galaxy NGC 5248 (Jogee et al. 2002a, b) based on a combination of multi-wavelength observations and hydro-dynamical modeling. A deep R-band image reveals that what was previously ... -

Fourier dissection of early-type galaxy bars

From Gas to Starburst and AGN
Knapen, J. (Astronomical Society of the Pacific, 2004)Although it is clear that the circumnuclear regions of galaxies are intimately related to their host galaxies, most directly through their bars, it remains unclear what exactly initiates and fuels nuclear stellar (starburst) ... -
