用新的radio telescopes进行弱透镜研究的前景

Prospects for weak lensing studies with new radio telescopes

Michael L Brown

摘要:

我概述了现在和将来使用新一代射电望远镜进行弱透镜研究的前景。我包括一个建议的技术,使用偏振观测无线电弱透镜分析,可以证明是非常有用的去除污染信号的内在对齐的描述。最终,平方公里阵列有望成为一个特殊的仪器进行弱透镜研究,由于高分辨率,大面积的调查,它将执行。在近期,英国的e-MERLIN仪器提供了证明无线电波段弱透镜技术所需的高灵敏度和亚弧秒分辨率。我描述的SuperCLASS调查-最近接受的电子MERLIN遗产计划,将进行开创性的无线电弱透镜分析的超星系团。

英文摘要:

I outline the prospects for performing weak lensing studies with the new generation of radio telescopes that are coming online now and in the future. I include a description of a proposed technique to use polarization observations in radio weak lensing analyses which could prove extremely useful for removing a contaminating signal from intrinsic alignments. Ultimately, the Square Kilometre Array promises to be an exceptional instrument for performing weak lensing studies due to the high resolution, large area surveys which it will perform. In the nearer term, the e-MERLIN instrument in the UK offers the high sensitivity and sub-arcsec resolution required to prove weak lensing techniques in the radio band. I describe the SuperCLASS survey -- a recently accepted e-MERLIN legacy programme which will perform a pioneering radio weak lensing analysis of a supercluster of galaxies.
