摘要:

对暗能量的进一步研究推动了下一代深、宽视场光学/红外探测的大部分科学案例。这是一个值得称赞的目标(也是Zhan等人的配套白皮书的主题)。然而,当前这一代调查最重要的教训之一是,调查结束时有趣的科学问题与计划调查时大不相同。目前的调查在这一不断变化的领域取得了成功,因为它们是非常通用的工具,可以应用于一些非常基本的测量。同样,数据的可访问性使更广泛的宇宙学和天文学社区能够产生比调查合作本身更多的科学。考虑到这一点,我们应该考虑一些基本的物理和宇宙学问题,像LSST和JDEM-Wide这样的调查将能够解决。

英文摘要:

Much of the science case for the next generation of deep, wide-field optical/infrared surveys has been driven by the further study of dark energy. This is a laudable goal (and the subject of a companion white paper by Zhan et al.). However, one of the most important lessons of the current generation of surveys is that the interesting science questions at the end of the survey are quite different than they were when the surveys were being planned. The current surveys succeeded in this evolving terrain by being very general tools that could be applied to a number of very fundamental measurements. Likewise, the accessibility of the data enabled the broader cosmological and astronomical community to generate more science than the survey collaborations could alone. With that in mind, we should consider some of the basic physical and cosmological questions that surveys like LSST and JDEM-Wide will be able to address.
