- IFS (107"x107") taken with the Mitchell Spectrograph on the 2.7m Harlan J. Smith telescope at the McDonald Observatory (Green et al. 2013)
- 1903.08884 早型星系中的分子气体
- 有分子气体detection的比例(大概1/4)似乎与质量,尺度等无关
- 与运动学有关 fast rotators 中的比例更高(morphology transform?),但slow rotator中也有,只是比例低
- 高密区,除了BCG外,有分子气体的比例很低
