The first talk I heard where there was a strong claim that supermassive
BH's (SBHs) exist in *most* galaxies, maybe all, was a review talk at
the Kyoto (1997) IAU. The general opinion is that there is an observational
relation between bulge mass - of all galaxies - and SBH mass. The most
"late-type" spirals, which should really be called "disk" galaxies, 
have small bulges, and so are expected to have the lowest mass SBHs.

Observationally, the mass is between the velocity dispersion of the 
bulge "sigma" and the SBH mass (OK, that is not directly observed either).

Here's a nice long list. I wonder if something in the software between 
my computer and the final web archive will cut off the string which is 
longer than 80 characters...,2000,1999,1998,1997/0/0

I've picked what seem (to me) to be the interesting ones.

I remember that from astro-ph abstracts, there has been debate about
whether the relation M_SBH/M_bulge is linear (always about 15%) or
non-linear. Since almost no astrophysical mass relation has nice power
law indexes, I'm sure it's unlikely to be exactly unity, and more likely
to be a broken power law with two regimes ;-)  - the trick will be to
work out why, and separate the cosmological and non-cosmological parts...

I've ***-ed the explicitly non-AGN articles.

Is there an SBH consistent with the claimed relation in the spiral M33? 
Maybe: Merritt et al.
No: Gebhardt et al.
(I find Merritt et al. more convincing.)

Thanks for asking for that. It gave me a good excuse to look up
some fun stuff which I'm not working on directly. Which will be useful
as a reference later on (if it's not outdated).

You'll have to do the work of finding the published references, at, not everybody takes the effort to add
these to astro-ph...
