Studies in cosmology, galaxies and telescopes

宇宙学和星系形成是嘉伯的主要研究兴趣。他共同领导了美国国家天文中心的调查和拉斯坎帕纳斯红外调查，并帮助发起了双子座深深调查，所有这些都极大地推进了宇宙学和星系演化的知识。他目前的主要研究工作是加拿大-法国-夏威夷望远镜遗产调查（SNLS）的超新星宇宙学组成部分。SNLS是一项滚动搜索成像调查，它吸引了世界上许多最大的望远镜的注意，以获取后续光谱数据。该合作小组已经提交了一份基于前71颗超新星（预计有700颗）的论文，这些超新星已经对推动宇宙加速的暗能量的特性给出了严格的新约束。这项调查的目的是控制可能扭曲宇宙测量的系统效应，并将导致对超新星物理学的深入了解。Carlberg也是大型光学望远镜项目的项目主管，该项目是30米望远镜项目的四个平等合作伙伴之一。

Cosmology and galaxy formation are Carlberg's primary research interests. He co-lead the CNOC survey and the Las Campanas Infrared Survey and helped originate the Gemini Deep Deep Survey, all of which significantly advanced the knowledge of cosmology and galaxy evolution. His major current research effort is the supernova cosmology component of the Canada France Hawaii Telescope Legacy Survey, SNLS. SNLS is a rolling search imaging survey which has captured the attention of many of the world's largest telescopes for follow-up spectroscopic data. The collaboration has submitted a paper based on the first 71 supernovae (of 700 anticipated) already giving a tight new constraint on the properties of the Dark Energy that drives the acceleration of the universe. The survey is designed to control possible systematic effects which could distort the cosmological measurement and will lead to insight into the physics of supernovae. Carlberg is also the Project Director of the Large Optical Telescope Project, which is one of four equal partners in the Thirty Meter Telescope Project.
