Dwarf Galaxy Clustering and Missing Satellites
R. G. Carlberg, M. Sullivan, D. Le Borgne
At redshifts around 0.1 the CFHT Legacy Survey Deep fields contain some 6x10^4 galaxies spanning the mass range from 10^5 to 10^12 Msun. We measure the stellar mass dependence of t…
The effect of progenitor age and metallicity on luminosity and 56Ni yield in Type Ia supernovae
D. A. Howell, M. Sullivan, E. F. Brown +23
Timmes, Brown & Truran found that metallicity variations could theoretically account for a 25% variation in the mass of 56Ni synthesized in Type Ia supernovae (SNe Ia), and thus ac…
Red Nuggets at z~1.5: Compact passive galaxies and the formation of the Kormendy Relation
Ivana Damjanov, Patrick J. McCarthy, Roberto G. Abraham +13
We present the results of NICMOS imaging of a sample of 16 high mass passively evolving galaxies with 1.3<z<2, taken primarily from the Gemini Deep Deep Survey. Around 80% of galax…
The reversal of the star formation-density relation in the distant universe
D. Elbaz, E. Daddi, D. Le Borgne +11
We study the relationship between the local environment of galaxies and their star formation rate (SFR) in the Great Observatories Origins Deep Survey, GOODS, at z~1, from ultradee…
The Gemini Deep Deep Survey. VII. The Redshift Evolution of the Mass-Metallicity Relation
S. Savaglio, K. Glazebrook, D. Le Borgne +10
We have investigated the mass-metallicity (M-Z) relation using galaxies at 0.4<z<1.0 from the Gemini Deep Deep Survey and Canada-France Redshift Survey. Deep K and z' band photomet…
Evolutionary synthesis of galaxies at high spectral resolution with the code PEGASE-HR
Damien Le Borgne, Brigitte Rocca-Volmerange, Philippe Prugniel +3
We present PEGASE-HR, a new stellar population synthesis program generating high resolution spectra (R=10 000) over the optical range lambda=400--680 nm. It links the spectro-photo…
Photometric redshifts from evolutionary synthesis with PEGASE: the code ZPEG and the z=0 age constraint
Damien Le Borgne, Brigitte Rocca-Volmerange
Photometric redshifts are estimated on the basis of template scenarios with the help of the code ZPEG, an extension of the galaxy evolution model PEGASE.2 and available on the PEGA…
