Understanding how the star formation activity of galaxies evolves with cosmic time is one of the key issues in the study of galaxy formation and evolution. Interestingly, most star formation takes place in dusty galaxies, which mainly emit radiation in the far-infrared and submillimeter wavelength ranges. I will introduce how our view of the evolution of star-forming galaxies has changed recently, and then discuss the results from current infrared and submillimeter surveys focusing on nearby star-forming galaxies.

BIO
Ho Seong Hwang is a Research Professor at the Korea Institute for Advanced Study (KIAS) in Seoul, Korea. He obtained his PhD in Astronomy in 2007 from Seoul National University, before he hold a Research Folow at KIAS (2007-2009), CEA Saclay (2009-2011) and Havard-Smithsonian Center for Astrophysics (2011-2014). He has been a Research Professor at KIAS since Sept 2014. His research interest falls in a broad range of topics in observatoinal studies of both galaxy formation and cosmology, including large-scale structure of the Universe, galaxy interactions and mergers, environmental effects on galaxy properties, formation of galaxy clusters/groups, and so on. He is Co-PI of the JINGLE survey, an ongoing large program of the JCMT to obtain molecular gas and dust observations for a large sample of low-z galaxies.
