  Angle-resolved photoemission spectroscopy (ARPES) has played an important
role in determining the band structure and the superconducting gap structure of
iron-based superconductors. Here from the ARPES perspective, we briefly review
the main results from our group in the recent years on the iron-based
superconductors and their parent compounds, and depict our current
understanding on the antiferromagnetism and superconductivity in these
materials.
