UCL Astrophysics PATT Travel Grant 2020-22

UCL的天体物理学小组参与使用世界级的地面望远镜在几个领域进行研究。我们研究系外行星系统如何从尘埃和气体云中形成，致力于检测和表征成熟的行星系统，并通过恒星演化后期的动力学过程长期跟踪它们的特征。小组成员还研究恒星如何形成和死亡，特别是那些爆炸并将大量尘埃送回星际介质并为下一代恒星做出贡献的系统。星系演化也是UCL天体物理学组研究的基石，我们研究大尺度和宇宙早期历史中星系的形成，以及冷气体和尘埃如何有助于观察到的星系的生长和性质。我们参加了ENU-UK，它将在广泛的红移范围内观察3000万个星系，以测量宇宙的加速膨胀并了解暗能量。

The Astrophysics group at UCL is involved in using world-class, ground-based telescopes to carry out research in several areas. We study how exoplanetary systems form from clouds of dust and gas, work to detect and characterize mature planetary systems, and also track their signatures over the long term through dynamical processes at later stages of stellar evolution. Group members also study how stars form and die, and especially those systems that explode and contribute large amounts of dust back into the interstellar medium and contribute to the next generation of stars. Galaxy evolution is also a cornerstone of research in the UCL Astrophysics group, and we study both the formation of galaxies at large scales and during the early history of the Universe, as well as how cold gas and dust contributes to the growth and properties of observed galaxies. We participate in DESI-UK, which will observe 30 million galaxies over a wide range of redshifts to measure the accelerated expansion of the Universe and learn about dark energy.
