Arm and Interarm star formation in spiral galaxies
Stedman, S.; Knapen, J. (2001)We present an outline of our study of the effects of star formation on the different components of the interstellar medium in the discs of spiral galaxies, both globally and as a function of arm and interarm environment. ... -
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) -
The gravitational torque of bar in optically unbarred and barred galaxies
Block, D.L.; Puerari, I.; Knapen, J.; Elmegreen, B.; Buta, R.J.; Stedman, S.; Elmegreen, D.M. (2001-09) -
The Gravitational Torque of Bars
Puerari, I.; Block, D.L.; Knapen, J.; Elmegreen, B.; Buta, R.J.; Stedman, S.; Elmegreen, D.M. (Astronomical Society of the Pacific, 2002)We have determined the gravitational torque of a sample of 45 galaxies observed at K band with the 4.2m William Herschel Telescope. The results of this sample, combined with those for a sample of 30 galaxies previously ... -
The H alpha galaxy survey. I. The galaxy sample, H alpha narrow-band observations and star formation parameters for 334 galaxies
James, P.A.; Shane, N.S.; Beckman, J.E.; Cardwell, A.; Collins, C.A.; Etherton, J.; de Jong, R.S.; Fathi, K.; Knapen, J.; Peletier, R.F.; Percival, S.M.; Pollacco, D.L.; Seigar, M.S.; Stedman, S. (2004)We discuss the selection and observations of a large sample of nearby galaxies, which we are using to quantify the star formation activity in the local Universe. The sample consists of 334 galaxies across all Hubble types ... -
An Imaging survey of nearby spiral galaxies
Knapen, J.; Stedman, S. (Astronomical Society of the Pacific, 2002)We describe the progress of a large optical and near-infrared imaging study of a complete sample of 57 spiral galaxies. We have obtained B, I, K' and Ha imaging to map stellar populations and massive star formation (SF) ... -
A near-infrared imaging survey of nearby spiral galaxies
Stedman, S.; Knapen, J.; Bramich, D.M. (Astronomical Society of the Pacific, 2001)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 ... -
Penetrating the Mask: All Spiral Galaxies become barred on bar torque scales between zero and six
Block, D.L.; Buta, R.J.; Puerari, I.; Knapen, J.; Elmegreen, B.; Stedman, S.; Elmegreen, D.M. (2002) -
Structure and star formation in disc galaxies - I. Sample selection and near-infrared imaging

Structure and star formation in disk galaxies. II. Optical Imaging
Knapen, J.; Stedman, S.; Bramich, D.M.; Folkes, S.; Bradley, T.R. (2004-11)
