Interaction of supermassive black holes with their stellar and dark matter environments
(Springer, 2005-06-22)
While supermassive black holes probably gained most of their mass via accretion
of gas, the galactic nuclei in which they are currently situated are dominated
by stars. This article reviews recent theoretical work on the ...
Tracing black hole mergers through radio lobe morphology
(American Association for the Advancement of Science: Science, 2002-08-23)
Binary supermassive black holes are produced by galactic mergers as the black holes from the two galaxies fall to the center of the merged system and form a bound pair. The two black holes will eventually coalesce in an ...
Dark matter spikes and annihilation radiation from the galactic center
(American Physical Society, 2002-05-13)
The annihilation rate of weakly interacting cold dark matter particles at the galactic center could be greatly enhanced by the growth of a density spike around the central supermassive black hole (SBH). Here we discuss the ...
No supermassive black hole in M33?
(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 ...
Black hole demographics from the M•[BH] − σ[sigma] relation
(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 ...
