Weak lensing analysis techniques for Euclid

JBCA宇宙学小组积极参与了即将到来的欧几里得任务（欧空局的一项卫星任务，将于本世纪20年代初发射）。欧几里得的主要目标是了解导致观测到的宇宙加速膨胀的物理学原理（可能是一种暗能量，也可能是大尺度上引力的变化）。欧几里得用来解决这个问题的两个主要科学探测器之一是弱引力透镜技术。这个博士项目的重点是发展先进的统计技术，从欧几里得观测中稳健地提取弱透镜信号，并根据宇宙学模型解释测量结果。所开发的技术也将适用于未来的LSST和SKA设施。

The JBCA cosmology group is heavily involved with the forthcoming Euclid mission (an ESA satellite mission due to be launched in the early 2020s). The primary objective of Euclid is to understand the physics responsible for the observed accelerated expansion of the Universe (be that a type of Dark Energy or a modification to gravity on large scales). One of the two main scientific probes that Euclid will use to address this question is the technique of weak gravitational lensing. This PhD project is focussed on developing advanced statistical techniques for robustly extracting the weak lensing signal from the Euclid observations and for interpreting the measurements in terms of cosmological models. The techniques developed will also be applicable to the future LSST and SKA facilities.
