Spectroscopic ages and metallicities of stellar populations: validation of full spectrum fitting
M. Koleva, Ph. Prugniel, P. Ocvirk +2
Fitting whole spectra at intermediate spectral resolution (R = 1000 -- 3000), to derive physical properties of stellar populations, appears as an optimized alternative to methods b…
Analysis of stellar populations with large empirical libraries at high spectral resolution
Philippe Prugniel, Mina Koleva, Pierre Ocvirk +2
The stellar population models dramatically progressed with the arrival of large and complete libraries, ELODIE, CFLIB (=Indo-US) and MILES at a relatively high resolution. We show…
Comparison of different spectral population models
Mina Koleva, Philippe Prugniel, Pierre Ocvirk +3
We have compared simple stellar populations (SSPs) generated with different population synthesis tools: BC03, Vazdekis and Pegase.HR and different stellar libraries: ELODIE3.1, Ste…
Age and metallicity of Galactic clusters from full spectrum fitting
Mina Koleva, Philippe Prugniel, Pierre Ocvirk +1
We are using full spectrum fitting to determine the ages and metallicities of Galactic clusters (M67 and globular clusters). We find that the method is very accurate to measure the…
A Compact Cluster of Massive Red Galaxies at a Redshift of 1.51
P. J. McCarthy, H. Yan, R. G. Abraham +15
We describe a compact cluster of massive red galaxies at z=1.51 discovered in one of the Gemini Deep Deep Survey (GDDS) fields. Deep imaging with the Near Infrared Camera and Multi…
The Gemini Deep Deep Survey: VIII. When Did Early-type Galaxies Form?
Roberto G. Abraham, Preethi Nair, Patrick J. McCarthy +13
We have used the Hubble Space Telescope's Advanced Camera for Surveys (Ford et al. 2003) to measure the cumulative mass density in morphologically-selected early-type galaxies over…
