Ionized gas in quiescent galaxies: Temperature measurement and constraint on the ionization source
Man-Yin Leo Lee, Renbin Yan, Xihan Ji +5
In non-star-forming, passively evolving galaxies, regions with emission lines dominated by low-ionization species are classified as Low-Ionization Emission Regions (LIERs). The ion…

Asymmetric drift in MaNGA: Mass and radially-dependent stratification rates in galaxy disks
Matthew A. Bershady, Kyle B. Westfall, Shravan Shetty +5
We measure the age-velocity relationship from the lag between ionized gas and stellar tangential speeds in ~500 nearby disk galaxies from MaNGA in SDSS-IV. Selected galaxies are ki…
