Characterizing SL2S galaxy groups using the Einstein radius
T. Verdugo, V. Motta, G. Foëx +11
We analyzed the Einstein radius, , in our sample of SL2S galaxy groups, and compared it with (the distance from the arcs to the center of the lens), using three differen…
The first Frontier Fields cluster: 4.5μm excess in a z~8 galaxy candidate in Abell 2744
N. Laporte, A. Streblyanska, B. Clement +10
We present in this letter the first analysis of a z~8 galaxy candidate found in the Hubble and Spitzer imaging data of Abell 2744, as part of the Hubble Frontier Fields legacy prog…
The bright-end of the luminosity function at z~9
N. Laporte, R. Pello, M. Hayes +6
We report new constraints on the galaxy luminosity function at z~9 based on observations carried out with ESO/VLT FORS2, HAWK-I and X-Shooter around the lensing cluster A2667, as p…
The dominant role of mergers in the size evolution of massive early-type galaxies since z ~ 1
C. López-Sanjuan, O. Le Fèvre, O. Ilbert +60
In this paper we measure the merger fraction and rate, both minor and major, of massive early-type galaxies (M_star >= 10^11 M_Sun) in the COSMOS field, and study their role in mas…
Improved constraints on the expansion rate of the Universe up to z~1.1 from the spectroscopic evolution of cosmic chronometers
M. Moresco, A. Cimatti, Raul Jimenez +65
We present new improved constraints on the Hubble parameter H(z) in the redshift range 0.15 < z < 1.1, obtained from the differential spectroscopic evolution of early-type galaxies…
Dissecting Photometric redshift for Active Galactic Nuclei using XMM- and Chandra-COSMOS samples
M. Salvato, O. Ilbert, G. Hasinger +61
With this paper, we release accurate photometric redshifts for 1692 counterparts to Chandra sources in the central square degree of the COSMOS field. The availability of a large tr…
