报告人:2012年毕业于中国科学技术大学，获得理学博士学位；攻读博士期间得到国家公派留学项目资助作为联合培养博士生赴剑桥大学学习、工作；博士毕业后在中国科学院紫金山天文台从事博士后研究；2015年入职广州大学。研究方向是星系物理、 星系的形成和演化、星系中的恒星形成和星际介质，以近邻星系为主要研究对象；研究领域包括星系的紫外、光学、红外、射电多波段观测特征，以及星系的本征物理和化学性质 —— 从星系组成要素（恒星、气体、尘埃）的属性（i.e., 静态方面的性质）， 到星系组建和成长的过程（i.e., 动态方面的性质），其中前者旨在以星系和星系的子区域为实验室来获得关于天体物理学基本原理和机制的新认识，后者旨在探索不同类别星系的起源、恒星形成历史和元素增丰历史，为星系的动力学演化和化学演化剧本提供素材。In this talk, I will report, primarily, two parts of case studies of nearby galaxies based on multiwavelengh analyses. The first part focuses on morphology of the early-type spiral galaxy M81 (NGC 3031). Via bulge-disk decomposition performed in 20-waveband images, morphological parameters as a function of wavelength are derived for the bulge and the disk, respectively, in M81. This results exhibit an intriguing feature and might have implication for studies of high-redshift galaxies. The other part of this talk will present a novel discovery of unique characteristics for M81's companion, the tidal dwarf galaxy (candidate) Holmberg IX. New Hα observations in combination with UV and IR archival/published data reveal its dustless but metal-rich, infant but inactive properties, which seem to be mysteries in contradiction with our common understanding. The peculiarity of Holmberg IX brings a conundrum about its formation and evolution, of which a follow-up exploration is planned. In the end of this talk, I will also share some relevant considerations and ideas regarding potential studies of nearby galaxies on the basis of WFST observations.
