No Periodicities in 2dF Redshift Survey Data
E. Hawkins, S. J. Maddox, M. R. Merrifield
We have used the publicly available data from the 2dF Galaxy Redshift Survey and the 2dF QSO Redshift Survey to test the hypothesis that there is a periodicity in the redshift dist…
Modern Techniques in Galaxy Kinematics: CDI and the Planetary Nebula Spectrograph
N. G. Douglas, K. Kuijken, A. J. Romanowsky +4
We report here the successful commissioning of the PN.Spectrograph, the first special-purpose instrument for the measurement of galaxy kinematics through the PN population
The Visibility of Galactic Bars and Spiral Structure At High Redshifts
Sidney van den Bergh, Roberto G. Abraham, Laura F. Whyte +4
We investigate the visibility of galactic bars and spiral structure in the distant Universe by artificially redshifting 101 B-band CCD images of local spiral galaxies from the Ohio…
Secular Evolution in Barred Galaxies: Observations
M. R. Merrifield
This paper describes a framework for studying galaxy morphology, particularly bar strength, in a quantitative manner, and presents applications of this approach that reveal observa…
