Star Formation along the Hubble sequence: results from a new Halpha Galaxy Survey
Neville S. Shane, Phil A. James
We are conducting a large survey of star formation within ~400 nearby spiral and irregular galaxies through imaging of the Halpha emission. We present here some of our first result…
A test of arm induced star formation in spiral galaxies from near-IR and Hαimaging
M. S. Seigar, P. A. James
We have imaged a sample of 20 face-on spiral galaxies in Hαand in the near-IR K-band (2.2 microns), in order to determine the location and strength of star formation with respect t…
X-ray Clusters and the Search for Cosmic Flows
P. D. Lynam, C. A. Collins, P. A. James +2
We are engaged in an investigation of the relationship between the properties of BCG candidates and X-ray characteristics of their host clusters for a flux-limited sample of ~250 A…
The structure of spiral galaxies - I. Near-infrared properties of bulges, disks and bars
M. S. Seigar, P. A. James
We present data for a sample of 45 spiral galaxies over a range of Hubble types, imaged in the near-IR J and K bands. Parameters are calculated describing the bulge, disk and bar K…
