The H alpha Galaxy Survey. IV. Star formation in the local Universe
P. A. James, J. H. Knapen, N. S. Shane +2
We present an analysis of the star formation properties of field galaxies within the local volume out to a recession velocity limit of 3000 km/s. A parent sample of 863 star-formin…
The H-alpha Galaxy Survey II. Extinction and NII corrections to H-alpha fluxes
P. A. James, N. S. Shane, J. H. Knapen +2
We study the two main corrections generally applied to narrow-band H-alpha fluxes from galaxies in order to convert them to star formation rates, namely for NII contamination and f…
The H alpha Galaxy Survey I. The galaxy sample, H alpha narrow-band observations and star formation parameters for 334 galaxies
P. A. James, N. S. Shane, J. E. Beckman +12
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 consist…
Scale Lengths in Disk Surface Brightness as probes of Dust Extinction in 3 Spiral Galaxies: M 51, NGC 3631 and M 100
J. E. Beckman, R. F. Peletier, J. H. Knapen +2
We have measured the radial brightness distributions in the disks of three nearby face-on spirals: M 51, NGC 3631, and NGC 4321 (M 100) in the photometric bands B through I, with t…
