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 State Key Lab (SKL) of Space-Ground Integrated Information Technology (SGIIT) is engaged in Astrometry, Planetary Sciences, Pulsar Timing and application, Star Clusters and the Milky Way research and the new Space technologies applied in the space-ground information network. Research areas include Exoplanets, Cepheids, Globular Clusters,  Pulsar timing and  astrophysics, galaxy formation and evolution, Laser Communication technology, star clusters and the structure of the Milk Way, High-precision Astrometry. There are now 38 faculty members, 12 postdocs, and 25 graduate students in the Lab.

The SKL of SGIIT was founded and operated by the Chinese Ministry of Science and Technology, the Space Star Co.Ltd., Chinese Academy of Space Technology. The SKL 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, Shanghai Astronomical Observatory, Pulsar research Collaborated with Pushchino Radio Astronomical Observatory (PRAO) of Russian Academy of Sciences, the joint-lab with Imperial College  London. We also participate in many international and domestic astronomical projects, including LAMOST, HXMT, FAST, the Sloan Digital Sky Survey IV, etc.
