A new chemo-evolutionary population synthesis model for early-type galaxies. I: Theoretical basis
A. Vazdekis, E. Casuso, R. F. Peletier +1
We have developed a new stellar population synthesis model designed to study early-type galaxies. It provides optical and near-infrared colors, and line indices for 25 absorption l…
A Counter-rotating Bulge in the Sb Galaxy NGC 7331
F. Prada, C. Gutierrez, R. F. Peletier +1
We have found that the bulge of the large, nearby Sb galaxy NGC 7331 rotates retrograde to its disk. Analysis of spectra in the region of the near-IR Ca II triplet along the major…
Ages of galaxy bulges and disks from optical and near-infrared colors
R. F. Peletier, M. Balcells
We compare optical and near-infrared colors of disks and bulges in a diameter-limited sample of inclined, bright, nearby, early-type spirals. Color profiles along wedge apertures a…
Scale Lengths in Disk Surface Brightness as probes of Dust Extinction in 3 Spiral Galaxies: M 51, NGC 3631 and M 100
J. E. Beckman, R. F. Peletier, J. H. Knapen +2
We have measured the radial brightness distributions in the disks of three nearby face-on spirals: M 51, NGC 3631, and NGC 4321 (M 100) in the photometric bands B through I, with t…
