A Study of the Faint Debris Remnant of Large Galaxy, Small Galaxy Interactions

星系可以通过吸积邻近的小星系而变得更大。这些事件产生的碎片在成长中的星系外围留下了恒星的痕迹。通过分析碎片，科学家们希望重建这些动荡事件是如何展开的。碎片发出的星光在可见光波段非常微弱。对这种低表面亮度碎片的观测直到最近才成为可能。研究小组将使用先进的理论和模拟来对碎片的结构进行分类。该小组的统计学家将分离出对重建最有帮助的结构。届时，观察人士将寻找这样的泄密结构。高级团队成员将培训初级成员。在她的全国学术访问期间，PI将讨论少数民族在科学领域面临的障碍。通过与非营利组织的合作，该团队将与纽约市服务不足的高中生接触。研究小组将研究小型吸积星系毁灭后在星系晕中留下的碎片结构。该团队的目标是：(1)对预期结构进行理论估计，(2)创建模拟星系晕的综合调查库，(3)开发和测试结构各种特性的统计测量。

Galaxies can grow bigger by accreting smaller, neighboring galaxies. The debris from such events leaves trails of stars in the outskirts of the growing galaxy. By analyzing the debris, scientists hope to reconstruct how these tumultuous events unfolded. The starlight from the debris is extremely faint at optical wavelengths. Observations of such low-surface-brightness debris have been possible only recently. The team will use cutting-edge theory and simulations to catalog the kinds of structures expected for the debris. The team's statistician will isolate the structures that help the most with the reconstructions. Observers will then look for such telltale structures. Senior team members will train junior members. During her colloquium visits nation-wide, the PI will discuss barriers facing minorities in science. Through a partnership with a non-profit, the team will engage with underserved high school students in New York City.The team will study debris structures left in galaxy halos by the destruction of small, accreted galaxies. The goals of the team are to (1) make theoretical estimates of the expected structures, (2) create libraries of synthetic surveys of simulated galaxy halos, and (3) develop and test statistical measures of various properties of the structures.
