通过Ostriker-Vishniac效应透镜观测高红移星系团
Observing high redshift galaxy clusters through lensing of the Ostriker-Vishniac effect
摘要：
在本文中，我们研究了在高分辨率和高灵敏度的CMB实验中检测透镜信号的可能性。在低于1弧分的尺度下，CMB背景在簇中由Sunyaev-Zel'dovich效应主导，在其他地方由Ostriker-Vishniac效应扭曲主导。假设可以去除簇中的Sunyaev-Zel'dovich分量，我们专注于Ostriker-Vishniac效应，并研究其检测的可能性，同时特别注意污染物，如仪器噪声和点源。在为这个特定的透镜信号设计了一个最佳滤波器之后，我们探索了不同情况下的信噪比，实验的分辨率、灵敏度和点源的污染水平都不同。我们的研究结果表明，下一代实验应该能够通过Ostriker-Vishniac背景的透镜效应进行新的和令人兴奋的科学研究。
英文摘要：
In this paper we study the possibility of detecting lensing signals in high-resolution and high-sensitivity CMB experiments. At scales below 1 arcmin, the CMB background is dominated by the Sunyaev-Zel'dovich effect in clusters and by Ostriker-Vishniac effect distortions elsewhere. Assuming the Sunyaev-Zel'dovich component in clusters can be removed, we focus on the Ostriker-Vishniac effect and study the possibility of its detection while paying special attention to contaminants, such as instrumental noise and point sources. After designing an optimal filter for this particular lensing signal we explore the signal-to-noise ratio for different scenarios varying the resolution of the experiment, its sensitivity, and the level of contamination due to point sources. Our results show that the next generation of experiments should be able to do new and exciting science through the lensing effect of the Ostriker-Vishniac background.
