|Title:||Galaxy formation in the first billion years of the Universe: progress, big questions, and future|
|Speaker:||Dr. Xiangcheng Ma (University of California, Berkeley)|
Understanding the formation of galaxies in the first billion years of the Universe is one of the key questions in galaxy evolution as well as cosmic reionization. Despite the remarkable progress on finding large samples of z>5 galaxies in the past few years, many big questions still remain unsolved. I will review recent progress and major challenges in this field and introduce a suite of high-resolution cosmological zoom-in simulations down to z=5 with realistic models of the ISM, star formation, and stellar feedback. I will summarize what we have learned from these simulations and how the results motivate future theoretical and observational work.
