摘要：
低表面亮度（LSB）结构是银河系复杂质量组装的证据，专门研究它们有助于我们深入了解星系的演化历史。此外，研究LSB区域中的恒星形成（SF）特性可以拓宽我们对低表面气体密度区域中恒星形成活动的理解，从而揭示基本的宇宙过程。然而，系统性不确定性可能会阻碍对LSB宇宙的探索，因为它们会限制可检测的SB水平。事实上，尽管数十年来在望远镜和观测技术方面取得了专门的进步，但在光学波长上实现超深光度深度仍是一个严峻的挑战。为克服这一挑战并探索我们尚未看到的LSB宇宙，我们正在开发一种新型望远镜，称为K-DRIFT。本文概述了望远镜的规格，并描述了我们旨在研究的各种LSB特征，特别关注附近的单个星系。为了进一步提升K-DRIFT调查的能力，专注于LSB检测，我们提出了几个可行的研究课题，这些课题利用其他调查数据，并讨论了LSB观测在理解星系演化中的作用。
英文摘要：
Low-surface-brightness (LSB) structures serve as evidence of the intricate mass assembly of galaxies, and dedicatedly studying them promises to give us profound insights into the evolutionary history of galaxies. Furthermore, delving into the properties of star formation (SF) in the LSB regime can broaden our understanding of SF activity in regions characterized by low surface gas density, thereby shedding light on fundamental cosmic processes. However, systematic uncertainties may hamper the exploration of the LSB universe by limiting detectable SB levels. Indeed, despite dedicated advancements in telescope and observing techniques over decades, achieving ultra-deep photometric depths in optical wavelengths remains a formidable challenge. To overcome this challenge and explore the LSB universe that we have yet to see, we have been developing a novel telescope called K-DRIFT. This paper outlines the telescope's specification and describes various LSB features we aim for, explicitly focusing on nearby individual galaxies. To further advance the capabilities of the K-DRIFT survey, focused on LSB detection, we present several feasible research topics that utilize other survey data together and discuss the role of LSB observation in understanding the evolution of galaxies.
