    • Black hole demographics from the M•[BH] − σ[sigma] relation 

      Merritt, David; Ferrarese, Laura (Monthly Notices of the Royal Astronomical Society, 2001-01)
      We analyze a sample of 32 galaxies for which a dynamical estimate of the mass of the hot stellar component, Mbulge, is available. For each of these galaxies, we calculate the mass of the central black hole, M•, using the ...
    • The Black hole mass of NGC 4151: comparison of reverberation mapping and stellar dynamical measurements 

      Onken, Christopher; Valluri, Monica; Peterson, Bradley; Pogge, Richard; Bentz, Misty; Ferrarese, Laura; Vestergaard, Marianne; Crenshaw, Michael; Sergeev, Sergey; McHardy, Ian; Merritt, David; Bower, Gary; Heckman, Timothy; Wandel, Amri (American Astronomical Society - The Astrophysical Journal, 2007-11-20)
      We present a stellar dynamical estimate of the black hole (BH) mass in the Seyfert 1 galaxy, NGC 4151. We analyze ground-based spectroscopy as well as imaging data from the ground and space, and we construct 3-integral ...
    • No supermassive black hole in M33? 

      Merritt, David; Ferrarese, Laura; Joseph, Charles (Science, 2001-08-10)
      We analyze optical long-slit spectroscopy of the nucleus of M33 obtained from the Space Telescope Imaging Spectrograph aboard the Hubble Space Telescope. Rather than the steep rise expected within the radius of influence ...
