摘要
GRavitational lEnsing Accuracy Testing 2008 (GREAT08) 挑战赛聚焦于一个对未来宇宙学观测至关重要的问题。遥远星系的形状可用于确定暗能量的属性和引力的本质，因为这些星系发出的光会被 intervening 暗物质的引力所弯曲。观测到的星系图像会出现畸变，尽管程度轻微，但必须将其形状从像素化、卷积和噪声的影响中精确解耦。全球引力透镜社区通过 Shear TEsting Program (STEP) 在测量这些畸变的技术方面取得了显著进展。通过 STEP，我们在社区内部开展了挑战赛，并认识到这一特定的图像分析问题非常适合统计推断、反问题和计算学习领域的专家。因此，为了延续近年来取得的进展，我们寻求来自这些社区的新思想注入。本文详细介绍了 GREAT08 挑战赛，供潜在参与者参考。请访问 http://www.great08challenge.info 获取最新信息。
