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).

该团队将研究已经观察到的从超大质量黑洞向一些星系中心出现的物质射流。 他们将在毫米波长下观察这些令人惊讶的窄喷流。 该团队将使用横跨地球的望远镜来实现精确的角分辨率。 他们将研究喷流的形状和喷流周围的等离子体。 他们还将对喷流进行计算机模拟，以帮助解释观测结果。 本科生将参与研究。 该小组将培训从波多黎各的阿雷西博天文台空间学院招募的高中生。 来访的研究生将获得仪器的实际操作经验。该团队将使用毫米波长的超长基线干涉测量法，以极高的角分辨率对遥远的喷流进行成像。 他们的主要工具是尖端的视界望远镜。 他们的目标是（1）研究射流的加速和准直区，（2）研究射流传播的等离子体，（3）进行射流的磁流体动力学模拟，作为解释（1）和（2）的框架。
