Mass distribution of spiral galaxies from characteristics of spiral structure: Constraints on galaxy formation models

Marc S. Seigar, Aaron J. Barth, James Bullock +1

Recently, it has been shown that a correlation exists between the rate of shear and the spiral arm pitch angle in disk galaxies. The rate of shear depends upon the shape of the rot…

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…

The nature of near-infrared emission from spiral galaxies

P. A. James, M. S. Seigar

We present K-band spectroscopy for several regions of three nearby spiral galaxies, NGC 613, NGC 628 and NGC 7741. Analysis of the depth of the 2.293 micron CO absorption feature i…

Spiral Galaxies with HST - Near Infrared Properties of Bulges

M. Seigar

We have obtained HST_NICMOS images for 72 nearby spiral galaxy bulges in the H-band. These data show that galaxies with regular bulges have steeper nuclear cusps than galaxies with…

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…
