To investigate star-forming activities in early-type galaxies, we select a sample of 52 star-forming S0 galaxies (SFS0s) from the SDSS-IV MaNGA survey. We find that SFS0s have smaller stellar mass compared to normal S0s in MaNGA. After matching the stellar mass to select the control sample, we find that the mean Sérsic index of SFS0s’ bulges (1.76±0.21) is significantly smaller than that of the control sample (2.57±0.20), suggesting the existence of a pseudo bulge in SFS0s. After introducing…

Radial stellar populations of AGN-host dwarf galaxies in SDSS-IV MaNGA survey
Based on MaNGA integral field unit (IFU) spectroscopy we search 60 AGN candidates, which have stellar masses M? 6 5 × 10M and show AGN ionization signatures in the BPT diagram. For these AGN
