The intriguing life of star-forming galaxies in the redshift range 1 < z < 2 using MASSIV
P. Amram, C. Lopez-Sanjuan, B. Epinat +13
MASSIV (Massiv Assembly Survey with SINFONI in VVDS) is an ESO large program which consists of 84 star-forming galaxies, spanning in a wide range of stellar masses, observed with t…
HeII emitters in the VIMOS VLT Deep Survey: PopIII star formation or peculiar stellar populations in galaxies at 2<z<4.6?
P. Cassata, O. Le Fevre, S. Charlot +15
The aim of this work is to identify HeII emitters at 2<z<4.6 and to constrain the source of the hard ionizing continuum that powers the HeII emission. We have assembled a sample of…
The Colors of Central and Satellite Galaxies in zCOSMOS out to z ~ 0.8 and Implications for Quenching
C. Knobel, S. J. Lilly, K. Kovac +47
We examine the red fraction of central and satellite galaxies in the large zCOSMOS group catalog out to z ~ 0.8 correcting for both the incompleteness in stellar mass and for the l…
A Strongly-Lensed Massive Ultra-Compact Quiescent Galaxy at z ~ 2.4 in the COSMOS/UltraVISTA Field
Adam Muzzin, Ivo Labbe, Marijn Franx +14
We report the discovery of a massive ultra-compact quiescent galaxy that has been strongly-lensed into multiple images by a foreground galaxy at z = 0.960. This system was serendip…
Detectors and cryostat design for the SuMIRe Prime Focus Spectrograph (PFS)
James E. Gunn, Michael Carr, Stephen A. Smee +20
We describe the conceptual design of the camera cryostats, detectors, and detector readout electronics for the SuMIRe Prime Focus Spectrograph (PFS) being developed for the Subaru…
A spectrograph instrument concept for the Prime Focus Spectrograph (PFS) on Subaru Telescope
Sébastien Vives, David Le Mignant, Fabrice Madec +10
We describe the conceptual design of the spectrograph opto-mechanical concept for the SuMIRe Prime Focus Spectrograph (PFS) being developed for the SUBARU telescope. The SuMIRe PFS…
