Shaping the Narrow Jets of Material from Supermassive Black Holes

该团队将研究观察到的从超大质量黑洞中涌出的物质喷向一些星系的中心。他们将在毫米波长观察到这些令人惊讶的窄喷流。该团队将使用跨越地球的望远镜来实现精致的角度分辨率。他们将研究喷流的形状和围绕喷流的等离子体。他们还将对喷气式飞机进行计算机模拟，以帮助解释观测结果。本科生将参与这项研究。该团队将对从波多黎各阿雷西博天文台太空学院招募的高中生进行培训。来访的研究生将获得仪器的实践经验。该团队将使用毫米波长的非常长的基线干涉法来拍摄具有极高角度分辨率的远处喷气式飞机的图像。他们的主要工具是尖端的事件视界望远镜。他们的目标是(1)研究喷流的加速和准直区，(2)研究喷流在其中传播的等离子体，以及(3)对喷流进行磁流体动力学模拟，以此作为解释(1)和(2)的框架。

The team will study the jets of material that have been observed to emerge from supermassive black holes toward the center of some galaxies. They will observe these surprisingly narrow jets at millimeter wavelengths. The team will use Earth-spanning telescopes to achieve exquisite angular resolution. They will study the shapes of the jets and the plasma that surrounds the jets. They will also make computer simulations of the jets to help interpret the observations. Undergraduates will be involved in the research. The team will train high school students recruited from the Arecibo Observatory Space Academy in Puerto Rico. Visiting graduate students will obtain hands-on experience with instrumentation.The team will use very long baseline interferometry at millimeter wavelengths to image distant jets with extremely-high angular resolution. Their chief tool is the cutting-edge Event Horizon Telescope. Their goals are to (1) study the acceleration and collimation zones of the jets, (2) study the plasmas within which the jets propagate, and (3) conduct magnetohydrodynamic simulations of jets as a framework for interpreting (1) and (2).
