AINUR: Atlas of Images of NUclear Rings
S. Comeron, J. H. Knapen, J. E. Beckman +4
We present the most complete atlas of nuclear rings to date. We include 113 rings found in 107 galaxies, six of which are elliptical galaxies, five are highly inclined disc galaxie…
Do Bars Drive Spiral Density Waves?
R. J. Buta, J. H. Knapen, B. G. Elmegreen +5
We present deep near-infrared K_s-band AAT IRIS2 observations of a selected sample of nearby barred spiral galaxies, including some with the strongest known bars. The sample covers…
Bars, ovals and lenses in early-type disk galaxies: probes of galaxy evolution
E. Laurikainen, H. Salo, R. Buta +1
The origin of S0 galaxies is discussed in the framework of early mergers in a Cold Dark Matter cosmology, and in a scenario where S0s are assumed to be former spirals stripped of g…
