Conference: Diffuse Cosmic Backgrounds and the Low Surface Brightness Universe

《漫射宇宙背景与低表面亮度宇宙》会议将于2024年4月在阿斯彭物理中心举行。这笔赠款将主要支持初级科学家根据需要参加。会议将集中讨论宇宙背景红外光的观测和理论，以及它们如何与宇宙历史上的星系群和低表面亮度结构相联系。会议将讨论以下问题：(I)宇宙中光产生的历史是什么，包括所有可能的来源？(Ii)像JWST和Rubin这样的大型新设施将教会我们什么？(3)矮小星系、低表面亮度天体和晕内光在宇宙的重子预算中扮演什么角色？(Iv)我们可以从蜻蜓或秃鹰等低成本地面仪器中学到什么？这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

The "Diffuse Cosmic Backgrounds and the Low Surface Brightness Universe" conference will be held at the Aspen Center for Physics in April 2024. This grant will support the participation of primarily junior scientists on a need-based basis.The conference will focus on observations and theory of the cosmic background OIR light and how they connect to the populations of galaxies and low surface brightness structures over the history of the universe. The conference will address the following questions: (i) What is the history of light production in the universe, including all possible sources? (ii) What will large new facilities like JWST and Rubin teach us about this? (iii) What role do dwarf galaxies, low surface brightness objects, and the intra-halo light play in the baryon budget of the universe? (iv) What can we learn from low-cost ground-based instruments such as Dragonfly or Condor?This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
