XMM-Newton study of six massive, X-ray luminous galaxy clusters systems in the redshift range z = 0.25 to 0.5
H. Boehringer, G. Chon, R. S. Ellis +2
Massive galaxy clusters are interesting astrophysical and cosmological study objects, but are relatively rare. In the redshift range z = 0.25 to 0.5 which is, for example, a favour…
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…
Probing the z>6 Universe with the first Hubble Frontier Fields cluster Abell 2744
Hakim Atek, Johan Richard, Jean-Paul Kneib +8
The Hubble Frontier Fields (HFF) program combines the capabilities of the Hubble Space Telescope (HST) with the gravitational lensing of massive galaxy clusters to probe the distan…
A peculiar galaxy appears at redshift 11: properties of a moderate redshift interloper
Matthew Hayes, Nicolas Laporte, Roser Pello +2
Laporte et al. (2011) reported a very high redshift galaxy candidate: a lensed J-band dropout (A2667-J1). J1 has a photometric redshift of z=9.6-12, the probability density functio…
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…
Optical dropout galaxies lensed by the cluster A2667
Nicolas Laporte, Roser Pelló, Daniel Schaerer +8
We investigate the nature and the physical properties of z, Y and J-dropout galaxies selected behind the lensing cluster A2667. This field is part of our project aimed at identifyi…
