    SDSS galaxies with double-peaked emission lines: double starbursts or active galactic nuclei?
    With the aim of investigating galaxies with two strong simultaneous starbursts, we have extracted a sample of galaxies with double-peaked emission lines in...

    SDSS-IV MaNGA: Spatial Evolution of Star Formation Triggered by Galaxy Interactions
    Galaxy interaction is considered a key driver of galaxy evolution and star formation (SF) history. In this paper, we present an empirical picture of the radial...
