Cosmology and telescopes

卡尔伯格的研究工作涵盖宇宙学、星系和望远镜。整整十年前，卡尔伯格是CFHT遗产调查“三层”设计的带头人之一，他自己的兴趣集中在以超新星宇宙学为主要科学驱动力的深层组件上。基于对第一年数据的初步分析对暗能量参数的测量产生了有史以来被引用最多的CFHT论文。基于整整五年的数据，更丰富的分析仍在继续，我们现在基本上实现了对w进行5%统计精度测量的目标。 现在人们在星系的光环中发现了大量细长的潮汐流。这些流可能是星系晕中预测的亚结构的潜在有力指标。Carlberg正在与一名学生一起进行n体模拟，扩展已发表的测试粒子研究，并与熊猫M31团队合作，以表征令人震惊的125kpc西北溪流中的密度变化。 Carlberg是加拿大大型光学望远镜拨款的PI，该项目主要从事30米望远镜工作，但也与ESO E-ELT项目保持联系。目前的赠款即将到期，新的赠款可能需要一份建设协议，这可能需要一些时间才能敲定。要求提供资金以支持持续的管理层参与。六年前，卡尔伯格在规模小得多但非常令人兴奋的情况下，开始了对埃尔斯米尔岛潜在地点的研究。这项工作在多伦多的一名研究助理的帮助下继续进行，并吸引了HIA的兴趣和支持，HIA的Paul Hickson证明，这些网站确实具有使其具有国际竞争力的预期品质。我们计划继续测试，并在未来五年内安装一台1-2米衍射限制望远镜。

Carlberg's research work covers cosmology, galaxies and telescopes. A full decade ago Carlberg was one of the leaders in proposing the "three tiered" design of the CFHT Legacy Survey, with his own interests focussed on the deep component with supernova cosmology as the primary scientific driver. The measurement of the dark energy parameter based on the preliminary analysis of the first year data produced the most highly cited CFHT paper ever. Much richer analyses are continuing based on the full five years of data and we have now substantially achieved the goal of a 5% statistical accuracy measurement of w. Long, thin tidal streams are now being discovered in abundance in the halos of galaxies. These streams are potentially powerful indicators of the predicted substructure in the halos of galaxies. Carlberg is doing n-body simulations with a student, extending the published test particle studies, and collaborating with the PAndAS M31 team to characterize the density variations in the astonishing 125 kpc NW stream. Carlberg is the PI for the Canadian grants for the Large Optical Telescope which is primarily engaged with Thirty Meter Telescope work, but also maintains links with the ESO E-ELT project. The current grants are expiring and new grants are likely to require a construction agreement which is likely to take some time to finalize. Funds to support ongoing management engagement are requested. At a much smaller but very exciting scale, Carlberg initiated studies of potential sites on Ellesmere Island six years ago. This effort has continued with a research assistant at Toronto, and attracted interest and support from HIA and Paul Hickson at HIA has demonstrated that the sites do have the expected qualities which would make them internationally competitive. We plan to continue testing and put a 1-2m diffraction limited telescope in place over the next five years.
