Decoding the spectral energy distribution of  the Milky Way and local Universe galaxies

Knowledge of the output and three dimensional distribution of all constituents of galaxies, stars of all ages, gas, dust, and cosmic rays, is a pre-requisite for understanding the process of star formation along the cosmic time, and ultimately the formation and evolution of galaxies. However, what we observe is the signature of the various galactic components, in terms of mainly photons of various energies. Thus, we measure the spatial and spectral energy distribution (SED) of galaxies which, ideally, should be modelled and converted into intrinsic properties of galaxies. From a pure mathematical point of view, this is equivalent with solving an inverse problem in a highly inhomogeneous medium, involving highly anisotropic processes that operate at multiple scales. In this talk I will show that radiative transfer models are powerful tools in solving this inverse problem and I will review past and recent progress in this field. In particular I will present our recent results on modelling the Milky Way and nearby face-on galaxies.

Prof. Popescu got her PhD in Max-planck-instutute for  nuclear physics in 1996, then  she worked in Max-planck-institute for  astronomy and in Max-planck-instutute for  nuclear physics as postdoc. Since 2017 she worked in university of central Lancashire (UCLan) as a full professor  in astrophysics. She is the  pioneer expert in the field of self-consistent modelling of the panchromatic spectral energy distribution of galaxies, and has published more 100 papers in the refereed journals with a H-index of 55. She also serves as the vice-president of IAU Division J (galaxies and cosmology) since 2021. 

中国科大寰宇开物天文讲坛是由中国科学技术大学物理学院天文学系主办、蔻享学术协办的天文前沿学术讲坛，内容涉及行星、恒星、星系与活动星系、宇宙大尺度结构、宇宙学等天体物理前沿领域的最新研究进展，致力于为广大天文科研工作者与关注天文研究进展的人们提供一个学术交流与天文知识传播的平台。“寰宇”取自严济慈先生在1988年为科大创办30周年而题写的“创寰宇学府，育天下英才”，“开物”源于中国古代科学著作《天工开物》；“寰宇开物”寓意为力求通晓宇宙中万物——这是天文学研究的不懈追求。The Universe, Yours to Discover!
