A complex multi-notch astronomical filter to suppress the bright infrared sky
J. Bland-Hawthorn, S. C. Ellis, S. G. Leon-Saval +10
A long-standing and profound problem in astronomy is the difficulty in obtaining deep near-infrared observations due to the extreme brightness and variability of the night sky at t…
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…
Euclid Definition Study Report
R. Laureijs, J. Amiaux, S. Arduini +216
Euclid is a space-based survey mission from the European Space Agency designed to understand the origin of the Universe's accelerating expansion. It will use cosmological probes to…
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…
Using the Bullet Cluster as a Gravitational Telescope to Study z~7 Lyman Break Galaxies
Nicholas Hall, Marusa Bradac, Anthony H. Gonzalez +7
We use imaging obtained with the Hubble Space Telescope Wide Field Camera 3 to search for z_850 dropouts at z~7 and J_110 dropouts at z~9 lensed by the Bullet Cluster. In total we…
