  • Information on stellar populations of the grand-design spiral galaxy UGC 3825 is exploited to measure the offset between young stars of a known age and the spiral arm in which they formed. The measured offset is consistent with a quasi-stationary density wave.

  • Counter-rotating gases demonstrate external gas acquisition in galaxies, but their presence in blue, star-forming galaxies has not been studied systematically. Here, the authors analyse the MaNGA survey data to find a fraction of counter-rotators among blue galaxies whose central regions show ongoing growth.
