Spectroscopic comparison between PS16dtm and three NLS1s, including the well-studied galaxy I Zw 1, one BAL QSO, and two TDEs (PS1-10jh and PS1-11af). Our +59- and +119-day spectra of PS16dtm are shown in pink and magenta, respectively. PS16dtm is strikingly similar to the spectra of NLS1s, most prominently in the Fe II emission complexes, consistent with a picture in which PS16dtm is an event related to the SMBH and surrounding gas structures.
