E. Legnani, J. Elvin-Poole, D. Anbajagane +72
Gravitational lensing magnification alters the observed spatial distribution of galaxies and must be accounted for to prevent biases in cosmological probes of the large-scale struc…
Euclid: Improving redshift distribution reconstruction using a deep-to-wide transfer function
Y. Kang, S. Paltani, W. G. Hartley +165
The Euclid mission seeks to understand the Universe expansion history and the nature of dark energy, which requires a very accurate estimate of redshift distribution. Achieving thi…
