MATLAS：对大质量早型星系周围环境的深入探测
MATLAS: a deep exploration of the surroundings of massive early-type galaxies
摘要：
MATLAS项目利用加拿大-法国夏威夷望远镜获得的多色深光学图像探索附近大质量早期型星系的完整样本的周围环境。观察和数据简化技术确保了对扩展的低表面亮度（LSB）结构的检测，而高图像质量使我们能够识别相关的紧凑物体，例如星团。本文简要介绍了这一数据集的一些科学主题：在高空间分辨率下对前景银河卷云的研究，告诉我们ISM结构;星系周围碰撞碎片的表征（流、尾、壳、恒星晕），暗示它们过去的合并历史;矮星系卫星的分布，包括超弥散卫星，以及它们的球状星团数量，这是星系形成和质量聚集的额外示踪物。
英文摘要：
The MATLAS project explores the surroundings of a complete sample of nearby massive early-type galaxies with multi-colour deep optical images obtained at the Canada-France Hawaii Telescope. The observing and data reduction techniques ensured the detection of extended low-surface-brightness (LSB) structures, while the high image quality allowed us to identify associated compact objects such as star clusters. A number of scientific topics are addressed with this data-set that are briefly presented in this review: the study of foreground Galactic cirrus at high spatial resolution, telling us about the ISM structure; the characterisation of collisional debris around the galaxies (streams, tails, shells, stellar halos), giving hints on their past merger history; the distribution of dwarf galaxy satellites, including the ultra-diffuse ones, together with their globular cluster population, which are additional tracers of the formation and mass assembly of galaxies.
