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

这个项目的目标是用MUSTANG2测量遥远星系团的物理性质，MUSTANG2是一台215像素的测辐射热计相机，在绿岸望远镜上观测3毫米波长。这将有助于理解早期宇宙的结构演化。更广泛的影响包括对本科生进行天文仪器方面的培训，特别是那些来自代表性不足群体的学生。此外，团队成员还积极参与费城地区的公众宣传活动，包括明星派对、费城科学节和对表现不佳的学校的指导。Sunyaev-Zel‘dovich效应是一种在穿过星系团时微波背景的减弱，它将在9角秒的角分辨率下观察到。其他进行这种测量的望远镜没有这样的分辨率。作者计划研究星系团物理的各个方面，包括标度关系、大半径的压力分布以及射电气泡中的压差。

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.
