Tests of Chemical Enrichment Scenarios in Ellipticals Using Continuum Colors and Spectroscopy
J. Schombert, K. Rakos
We combine spectroscopic metallicity values with integrated narrowband continuum colors to explore the internal metallicity distribution in early-type galaxies. The different techn…
The Age of Cluster Galaxies from Continuum Colors
K. Rakos, J. Schombert, A. Odell
We determine the age of 1,104 early-type galaxies in eight rich clusters ( to ) using a new continuum color technique. We find that galaxies in clusters divide i…
ARCHANGEL Galaxy Photometry System
J. Schombert
Photometry of galaxies has typically focused on small, faint systems due to their interest for cosmological studies. Large angular size galaxies, on the other hand, offer a more de…
The Rotation Velocity Attributable to Dark Matter at Intermediate Radii in Disk Galaxies
S. S. McGaugh, W. J. G. de Blok, J. M. Schombert +2
We examine the amplitude of the rotation velocity that can be attributed to the dark matter halos of disk galaxies, focusing on well measured intermediate radii. The data for 60 ga…
Age and Metallicities of Cluster Galaxies: A1185 and Coma
K. Rakos, J. Schombert, A. Odell
We present age and metallicities determinations based on narrow band continuum colors for the galaxies in the rich clusters A1185 and Coma. Using a new technique to extract luminos…
On the Structural Differences between Disk and Dwarf Galaxies
J. Schombert
Gas-rich dwarf and disk galaxies overlap in numerous physical quantities that make their classification subjective. We report the discovery of a separation between dwarfs and disks…
