Improving parametric mass modelling of lensing clusters through a perturbative approach
Benjamin Beauchesne, Benjamin Clément, Johan Richard +2
We present a new method to model the mass distribution of galaxy clusters that combines a parametric and a free-form approach to reconstruct cluster cores with strong lensing const…
The Extraordinary Amount of Substructure in the Hubble Frontier Fields Cluster Abell 2744
M. Jauzac, D. Eckert, J. Schwinn +21
We present a joint optical/X-ray analysis of the massive galaxy cluster Abell 2744 (z=0.308). Our strong- and weak-lensing analysis within the central region of the cluster, i.e.,…
Hubble Frontier Fields : A High-Precision Strong-Lensing Mass Model of the Massive Galaxy Cluster Abell 2744 using 180 Multiple Images
Mathilde Jauzac, Johan Richard, Eric Jullo +11
We present a high-precision mass model of galaxy cluster Abell 2744, based on a strong-gravitational-lensing analysis of the \emph{Hubble Space Telescope Frontier Fields} (HFF) ima…
Hubble Frontier Fields : A High Precision Strong Lensing Analysis of Galaxy Cluster MACSJ0416.1-2403 using ~200 Multiple Images
Mathilde Jauzac, Benjamin Clément, Marceau Limousin +11
We present a high-precision mass model of the galaxy cluster MACSJ0416.1-2403, based on a strong-gravitational-lensing analysis of the recently acquired Hubble Space Telescope Fron…
Hubble Frontier Fields: The Geometry and Dynamics of the Massive Galaxy Cluster Merger MACSJ0416.1-2403
Mathilde Jauzac, Eric Jullo, Dominique Eckert +13
We use a joint optical/X-ray analysis to constrain the geometry and history of the ongoing merging event in the massive galaxy cluster MACSJ0416.1-2403 (z=0.397). Our investigation…
Constraining the nature of the most distant Gamma-Ray Burst host galaxies
S. Basa, J. G. Cuby, S. Savaglio +5
Long duration gamma-ray bursts (GRBs) allow us to explore the distant Universe, and are potentially the most effective tracer of the most distant objects. Our current knowledge of…
A highly magnified supernova at z=1.703 behind the massive galaxy cluster Abell 1689
R. Amanullah, A. Goobar, B. Clément +17
Our ability to study the most remote supernova explosions, crucial for the understanding of the evolution of the high-redshift universe and its expansion rate, is limited by the li…
Evolution of the observed Ly-alpha luminosity function from z = 6.5 to z = 7.7: evidence for the epoch of reionization ?
B. Clément, J. -G. Cuby, F. Courbin +17
Aims. Ly-alpha emitters (LAEs) can be detected out to very high redshifts during the epoch of reionization. The evolution of the LAE luminosity function with redshift is a direct p…
The bright end of the z ~ 7 UV Luminosity Function from a wide and deep HAWK-I survey
M. Castellano, A. Fontana, D. Paris +23
(Abridged) We present here the second half of an ESO Large Programme, which exploits the unique combination of area and sensitivity provided in the near-IR by the camera Hawk-I at…
Limits on the luminosity function of Ly-alpha emitters at z = 7.7
P. Hibon, J. -G. Cuby, J. Willis +7
The Ly-alpha luminosity function (LF) of high-redshift Ly-alpha emitters (LAEs) is one of the few observables of the re-ionization epoch accessible to date with 8-10 m class telesc…
