A Keck/Deimos Survey of Red Giant Branch Stars in the Outskirts of M31
Annette Ferguson, Scott Chapman, Rodrigo Ibata +3
We are using the DEIMOS multi-object spectrograph on the Keck II 10m telescope to conduct a spectroscopic survey of red giant branch stars in the outskirts of M31. To date, velocit…
A best fit evolution scenario for the SCUBA galaxies
S. C. Chapman, G. F. Lewis, G. Helou
We explore the evolution of the SCUBA sub-mm galaxy population using Monte Carlo simulations to generate synthetic sub-mm/radio color magnitude diagrams. To represent the local dis…
First detections of FIRBACK sources with SCUBA
Douglas Scott, Guilaine Lagache, Colin Borys +10
The FIRBACK (Far InfraRed BACKground) survey represents the deepest extensive 170 micron images obtained by the ISO satellite. The sources detected comprise about 10% of the Cosmic…
B1933+503, a dusty radio quasar at z>2: implications for blank field sub-mm surveys?
Scott C. Chapman, Douglas Scott, Geraint F. Lewis +2
We present a detailed mm-wave and optical study of the gravitational lens system B1933+503, discovered by Sykes et al.(1998) in the radio. This object is probably the most complex…
The core structure of AGN: perils of adaptive optics artifacts
Scott C. Chapman, Simon L. Morris, Gordon A. H. Walker
As part of a project to map nearby Seyfert galaxies in the near-IR with adaptive optics, we present high spatial resolution, near-IR images in J,H, and K of the nuclei of NGC 3227…
