Structure and star formation in disk galaxies II. Optical imaging
J. H. Knapen, S. Stedman, D. M. Bramich +2
We present optical observations of a sample of 57 spiral galaxies and describe the procedures followed to reduce the data. We have obtained images in the optical B and I broad band…
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…
Structure and star formation in disk galaxies I. Sample selection and near infrared imaging
J. H. Knapen, R. S. de Jong, S. Stedman +1
We present near-infrared imaging of a sample of 57 relatively large, Northern spiral galaxies with low inclination. After describing the selection criteria and some of the basic pr…
Penetrating the Mask: The Gravitational Torque of Bars
D. L. Block, R. Buta, I. Puerari +4
The Hubble classification scheme of galaxies is based on blue-light appearance. Atlases reveal the rich variety of responses of the Population I component (the "mask") of gas and d…
The gravitational torque of bars in optically unbarred and barred galaxies
D. L. Block, I. Puerari, J. H. Knapen +4
The relative bar torques for 45 galaxies observed at - band with the 4.2m William Herschel Telescope are determined by transforming the light distributions into potentials and d…
