[M87 (StScI/AURA)] So far, in most models the contribution of the galaxy’s dark matter halo has been neglected. Gebhardt & Thomas (2009) recently showed that the black-hole mass can be underestimated... For the massive galaxy M87 they found an increase of more than a factor of 2 in the measured black-hole mass, just by including a dark matter halo in the modeling.
