High Resolution Observations of the Sunyaev-Zel'dovich Effect to Measure the Physics of Distant Clusters of Galaxies

该计划的目标是测量遥远星系团的物理学与MUSTANG 2，一个215像素的测辐射热相机观察在3毫米波长的绿色银行望远镜。 这将有助于理解早期宇宙结构的演化。更广泛的影响包括对本科研究生进行天文仪器方面的培训，特别是对来自代表性不足群体的研究生进行培训。 此外，该团队的成员积极参与费城地区的公共宣传活动，包括星星派对、费城科学节和在表现不佳的学校提供指导。Sunyaev-Zel'dovich效应，即微波背景在穿过星系团时的减少，将在9角秒的角分辨率下观测到。 其他进行这种测量的望远镜没有这种分辨率。作者计划研究星团物理的各个方面，包括标度关系，大半径的压力分布，以及射电泡中的压力差。

The goal of this program is to measure the physics of distant clusters of galaxies with MUSTANG2, a 215-pixel bolometer camera observing at 3mm wavelength on the Green Bank Telescope. This will help in understanding of the evolution of structure in the early universe. Broader impacts include training of undergraduate graduate students in astronomical instrumentation, especially those from underrepresented groups. In addition, members of the team are actively involved in public outreach in the Philadelphia area including star parties, the Philadelphia science festival, and mentoring in low-performing schools. The Sunyaev-Zel'dovich effect, a diminution in the Microwave Background as it passes through clusters, will be observed at 9 arc-second angular resolution. Other telescopes making such measurements do not have this level of resolution. The authors plan to examine various aspects of cluster physics, including scaling relations, pressure profiles to large radii, and pressure differences in radio bubbles.
