Studies in cosmology, galaxies and telescopes

宇宙学和星系形成是卡尔伯格的主要研究兴趣。他共同领导了中海油调查和拉斯坎帕纳斯红外调查，并帮助发起了双子座深度调查，所有这些都极大地促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)中的超新星宇宙学部分。SNLS是一种滚动搜索成像调查，它吸引了世界上许多最大的望远镜的注意，以获得后续的光谱数据。该合作小组提交了一篇基于第一批71颗超新星(预计有700颗)的论文，已经对驱动宇宙加速的暗能量的性质施加了严格的新限制。这项调查旨在控制可能的系统效应，这些效应可能会扭曲宇宙学测量，并将导致对超新星物理的洞察。卡尔伯格也是大型光学望远镜项目的项目总监，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.
