SHAO Astrophysics Colloquium


Title: The Curious Case of Lyman-alpha Emitting Galaxies
Speaker:Zheng Zheng (Physics and Astronomy at the University of Utah)

Time: 3 pm, January 18 (Thursday)

Location: Lecture Hall, 3rd floor

Abstract: Lyman-alpha Emitting galaxies or Lyman-alpha emitters (LAEs), star-forming galaxies selected through their strong Lyman-alpha emission, are becoming an important probe of galaxy formation, cosmic reionization, and cosmology. I will present our recent and ongoing work towards understanding some properties of those galaxies based on Lyman-alpha radiative transfer modeling, which includes the role of the anisotropic gas distribution around galaxies in shaping observed properties of LAEs and the origin of the extended Lyman-alpha emission around LAEs. I will also talk about the anisotropic clustering of LAEs induced by the radiative transfer effect and the current observational status. Finally, I will discuss some puzzles in the study of LAEs.

The Astrophysics division is the main group engaged in astrophysical research at Shanghai Astronomical Observatory. Research areas include active galactic nuclei and high energy astrophysics, galaxy formation and evolution, cosmology and large scale structure, star clusters and the structure of the Milk Way, star formation, and planetary astrophysics. There are now 45 faculty members, 16 postdocs, and 65 graduate students in the division.

The Astrophysics division maintains close partnerships with many astronomical research institutes, including the joint Key laboratory of research in galaxies and cosmology of CAS with University of Science and Technology of China, the joint astrophysics center with Xiamen University. Members of the astrophysics division also participate in many international and domestic astronomical projects, including LAMOST, HXMT, FAST, the Sloan Digital Sky Survey IV, TMT, LSST, etc.
