项目摘要
This project will study distant galaxies in the midst of shutting down their last burst of star formation and metamorphosing from spiral galaxies - like the Milky Way - into round and dead elliptical galaxies. Although this process is common, as most large galaxies are ellipticals while young galaxies are spirals, it is poorly understood. This project will use the detailed properties of newly transformed galaxies in stars and gas to test formation models. The broader impacts will support underrepresented minority students transition to graduate school through bridge programs at Princeton University and the University of Pittsburgh.This work assesses possible quenching mechanisms using a unique sample of intermediate-redshift massive post-starburst galaxies. These galaxies have recently quenched their major star-forming episode - yet they are sufficiently nearby that multi-wavelength observations can illuminate their detailed, spatially resolved stellar properties and molecular gas reservoirs. By combining the resolved kinematics, distribution of stellar ages, remaining gas content, and visual morphologies of this statistical sample of recently quenched massive galaxies and comparing with the timescales and stochasticity of quenching within the SIMBA cosmological simulations, this project will determine the dominant quenching mechanism(s) driving the transformation of blue star forming, rotating, disk galaxies into red-and-dead, kinematically hot, spheroids. In addition, the team will extend a proven program to broaden and strengthen support of post-baccalaureate students at Princeton and the University of Pittsburgh.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
这个项目将研究遥远的星系,在关闭它们最后一次恒星形成的过程中,从螺旋星系--比如银河系--蜕变为圆形和死椭圆星系。虽然这一过程很常见,因为大多数大星系是椭圆形的,而年轻的星系是螺旋形的,但人们对此知之甚少。该项目将使用恒星和气体中新转化的星系的详细性质来测试形成模型。更广泛的影响将支持未被充分代表的少数族裔学生通过普林斯顿大学和匹兹堡大学的桥梁项目过渡到研究生院。这项工作使用一个独特的中等红移大质量恒星爆发后星系样本来评估可能的猝灭机制。这些星系最近已经熄灭了它们的主要恒星形成阶段--但它们足够接近,以至于多波长观测可以照亮它们详细的、空间分辨的恒星性质和分子气藏。通过结合最近猝灭的大质量星系的统计样本的分辨运动学、恒星年龄分布、剩余气体含量和视觉形态,并与SIMBA宇宙模拟中猝灭的时间尺度和随机性进行比较,该项目将确定推动蓝星形成、旋转、盘状星系转变为红色和死亡的、运动学上热的球体的主要猝灭机制(S)。此外,该团队将扩展一项行之有效的计划,以扩大和加强对普林斯顿大学和匹兹堡大学毕业后学生的支持。该奖项反映了NSF的法定使命,并通过使用基金会的智力优势和更广泛的影响审查标准进行评估,被认为值得支持。
