超大望远镜时代的基础物理学和宇宙学

Fundamental Physics and Cosmology in the Extremely Large Telescopes Era

C. J. A. P. Martins

摘要:

最近宇宙加速的观测证据表明,宇宙学和粒子物理学的规范理论是不完整的(或可能是不正确的),新的物理学就在那里,等待被发现。下一代天体物理设施的一项关键任务是寻找、识别并最终验证这种新物理。我概述了指向这一新物理的理论论据,然后讨论了一些独特的贡献ELTs对这一努力,包括测试的稳定性的性质的基本耦合,测试的行为,在强场制度的引力,并映射宇宙的膨胀历史在深物质时代,通过直接和间接的手段。我还简要强调了ELT如何能够最佳地补充其他计划中的地面和空间设施,并强调这些搜索对目前正在建造或开发的仪器的要求。

英文摘要:

The observational evidence for the recent acceleration of the universe demonstrates that canonical theories of cosmology and particle physics are incomplete (or possibly incorrect) and that new physics is out there, waiting to be discovered. A crucial task for the next generation of astrophysical facilities is to search for, identify and ultimately characterise this new physics. I outline the theoretical arguments pointing to this new physics, and then discuss some unique contributions of the ELTs towards this endeavour, including tests of the stability of nature's fundamental couplings, tests of the behaviour of gravity in the strong-field regime, and mapping the expansion history of the universe in the deep matter era, by both direct and indirect means. I also briefly highlight how the ELTs can optimally complement other planned ground and space facilities, and stress the requirements that these searches impose on the instruments currently being built or developed.
