    hello there,

    I am searching for a list of the most massive galaxies and their central black holes, both with mass measurements/estimations. Is there anything like this available on the net? In particular I'm searching for a correlation between the galaxy and the SMBH masses (roughly M(Gal)/M(SMBH) ~ n x 100 with some valuable dispersion from n x 10 to n x 1000). I stumbled over the Tully-Fisher, the Faber-Jackson and the M-sigma relations, but they do not give an easy (linear?) correlation of the masses in question.
    In addition, I checked wikipedia for the cD ("giant elliptical galaxies") and the SMBHs, but the mass data/estimations especially for the gal's are frequently missing. A list of the most massive SMBHs is readily available https://en.wikipedia.org/wiki/List_of_most_massive_black_holes but no mass data for the galaxies around it.

    Any help will be gratefully acknowledged.

    thanx in advance, Wolfgang.

    Here is a paper on one way of estimating the masses in active and
    Seyfert galaxies from observation of spectral lines from MNRAS.
    Looks fairly plausible to me.

    Not really my field though. There may be lists try searching in SIMBAD
    or ADS abstracts and cross your fingers for a bit of good luck.
