UCL Astrophysics PATT Travel Grant 2020-22

伦敦大学学院的天体物理学小组参与了使用世界级的地面望远镜在几个领域进行研究。我们研究系外系统是如何由尘埃和气体云形成的，致力于探测和描述成熟的行星系统，并通过恒星演化后期的动力学过程追踪它们的长期特征。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带回星际介质并为下一代恒星做出贡献的系统。星系演化也是伦敦大学学院天体物理学小组研究的基石，我们既研究大尺度星系的形成，也研究宇宙早期历史期间的星系形成，以及冷气和尘埃如何有助于观测到的星系的生长和性质。我们参与了DESI-UK，它将在广泛的红移范围内观测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.
