Pᵉtɘr Wᵉil8acherI contributed a bit of data processing and got to be co-author on another paper in this month's A&A. 😀
Martin Ochmann was able to use narrow-field MUSE data to extract and model the Ca-triplet and OI emission (1st picture) of the accretion disk of NGC 4593. I know very little about AGN and their BLR but apparently the one can get a nearly perfect fit to a double-peaked CaII profile (2nd picture) using a not too complex disk model. The resulting low intrinsic turbulence seems to be something special...
