Massive Perturber-driven Interactions between Stars and a Massive Black Hole (2006, background): “These mechanisms include chaotic orbits in triaxial potentials (Norman & Silk 1983; Gerhard & Binney 1985; Merritt & Poon 2004; Holley-Bockelmann & Sigurdsson 2006) (the presence of a MBH may however destroy the triaxiality near the center; Merritt & Quinlan 1998; Holley-Bockelmann et al. 2002;…”
Finite, Intense Accretion Bursts from Tidal Disruption of Stars on Bound Orbits (2012, background): “…conversely, the triaxial, nonKeplerian potential of a surrounding star cluster results in fewer constants of motion for stellar orbits; in particular, angular momentum is not conserved and some stars can wander arbitrarily close to the SMBH, eventually being disrupted (Merritt & Poon 2004).”
The Causes of Halo Shape Changes Induced by Cooling Baryons: Disks versus Substructures (2007, background): “Box orbits play an important role in speeding up the mergers of supermassive black holes at the centers of galaxies (Merritt & Poon 2004).”
Consequences of Strong Compression in Tidal Disruption Events (2012, background): “Alternative mechanisms for enhancing the TDE rate include triaxiality in a galaxy’s nuclear potential (Merritt & Poon 2004), encounters with massive perturbers (Perets, Hopman & Alexander 2007), the effect of an inspiraling secondary SMBH (Ivanov, Polnarev & Saha 2005; Chen et al. 2009, 2011; Wegg…”
Dynamics of triple black hole systems in hierarchically merging massive galaxies (2006, background): “Merritt & Poon (2004) show that a significant fraction of stars on “centrophilic” orbits in a triaxial potential can greatly increase the mass flux into the loss cone.”
A bright year for tidal disruptions (2015, background): “…rates can be enhanced above the level set by two-body relaxation if axisymmetry (Magorrian & Tremaine 1999; Vasiliev & Merritt 2013) or triaxiality (Merritt & Poon 2004) exist in the stellar potential; in this case, orbits will not conserve all components of angular momentum, and some will…”
The evolution of massive black holes and their spins in their galactic hosts (2012, background): “…may be replenished by star- tar encounters (Milosavljević & Merritt 2003; Yu 2002), or as aresult of the triaxial gravitational potential that one naturlly expects in galaxies forming from major mergers (Merritt & Poon 2004; Berczik et al. 2006; Khan, Just, & Merritt 2011; Preto et al. 2011).”
Rates of stellar tidal disruption as probes of the supermassive black hole mass function (2014, background): “This modestly enhances TDE rates in axisymmetric systems (Magorrian & Tremaine 1999; Vasiliev & Merritt 2013) and can increase them dramatically in triaxial ones (Merritt & Poon 2004).”
Supermassive Black Holes in Active Galactic Nuclei. II. Calibration of the Black Hole Mass-Velocity Dispersion Relationship for Active Galactic Nuclei (2004, background): “…could be linked (e.g., Silk & Rees 1998; Haehnelt & Kauffmann 2000; Adams, Graff, & Richstone 2001; Umemura 2001; Miralda-Escudé & Kollmeier 2003; Merritt & Poon 2004), while others have looked for outliers from these relationships as probes of the physical drivers of the correlations (e.g.…”
Optical Flares from the Tidal Disruption of Stars by Massive Black Holes (2009, background): “This constraint already suggests that galactic nuclei in the nearby universe are relatively spherical, rather than triaxial, because the expected disruption rate is significantly higher in the latter case (Merritt & Poon 2004).”
Now You See It, Now You Don't: The Disappearing Central Engine of the Quasar J1011+5442 (2015, background): “…this would be a strong indication that the previous “on-state” was not caused by a TDE since the rate of such events is expected to be ∼ 10−5–10−4 galaxy−1 yr−1 (both on theoretical and observational grounds, e.g., Merritt & Poon 2004; Donley et al. 2002; Gezari et al. 2008; Maksym et al. 2010).”
Gravitational waves from resolvable massive black hole binary systems and observations with Pulsar Timing Arrays (2008, background): “…stellar distribution interacting with the binary may be efficiently repopulated as a consequence of non-axisymmetric or triaxial galaxy po- tentials (Merritt & Poon 2004, Berzcik et al. 2006), or by massive perturbers (Perets & Alexander 2008); moreover, if one considers post-Newtonian…”
EFFICIENT MERGER OF BINARY SUPERMASSIVE BLACK HOLES IN MERGING GALAXIES (2011, background): “Further evolution of the binary is possible, even in the absence of gas, if these orbits are replenished, or if the galaxy geometry allows for a much larger population of centrophilic orbits than in the spherical case (Merritt & Poon 2004; Berczik et al. 2005).”
Doing Science with eLISA: Astrophysics and Cosmology in the Millihertz Regime (2012, background): “…scatter individually off the black holes (Berczik et al., 2005, Makino and Funato, 2004, Merritt, 2006, Merritt et al., 2007, Merritt and Milosavljević, 2005, Merritt and Poon, 2004, Milosavljević and Merritt, 2001, Perets and Alexander, 2008, Quinlan, 1996, Sesana et al., 2006, 2007a, 2008a).”
Efficient Merger of Binary Supermassive Black Holes in Nonaxisymmetric Galaxies (2006, background): “…is Ṁ(E)dE= rtA(E)Mc(E)dE (2) whereA(E)d is the rate at which asinglestar on a centrophilic (e.g. box or chaotic) orbit of energyE experiences near-center passages with pericenter distances≤ d, and Mc(E)dE the mass in stars on centrophilic orbits with energies fromE to E+dE (Merritt & Poon 2004).”
Mass Deficits, Stalling Radii, and the Merger Histories of Elliptical Galaxies (2006, background): “The mass in stars on centrophilic orbits can be extremely large in a triaxial galaxy, although many orbital periods will generally be required before any given star passes near enough to the binary to interact with it (Merritt & Poon 2004; Holley-Bockelmann&Sigurdsson 2006).”
