Description
We present evidence for a strong correlation between the concentration of bulges and the mass of their central supermassive black hole (Mbh)-more concentrated bulges have more massive black holes. Using Cre(1/3) from Trujillo, Graham, & Caon as a measure of bulge concentration, we find that log(Mbh/Msolar)=6.81(+/- 0.95)Cre(1/3)+5.03+/-0.41. This correlation is shown to be marginally stronger (Spearman's rs=0.91) than the relationship between the logarithm of the stellar velocity dispersion and logMbh (Spearman's rs=0.86) and has comparable or less scatter (0.31 dex in logMbh, which decreases to 0.19 dex when we use only those galaxies whose supermassive black hole radii of influence are resolved and we remove one well-understood outlying data point).

However, detections are limited to strongly active regions because signal-to-noise ratio of the data is low.

    Inferring the coupling of different atmospheric layers requires observing spectral lines sensitive to the atmospheric parameters, particularly the magnetic field vector, at various heights. The best way to tackle this goal is to perform multi-line observations simultaneously. For instance, the new version of the Gregor Infrared Spectrograph
