In science:

Black hole mass measurements Under the assumptions of hydrostatic equilibrium, spherical symmetry, a single-phase ISM and a stellar mass component which follows the optical light, we have constrained the masses of the SMBHs at the centres of three galaxies.
Hydrostatic Gas Constraints on Supermassive Black Hole Masses: Implications for Hydrostatic Equilibrium and Dynamical Modelling in a Sample of Early-Type Galaxies
Combined with our previous measurement for NGC 4649 (H08), this demonstrates that hydrostatic X-ray methods are a practical, competitive means for SMBH mass determination.
Hydrostatic Gas Constraints on Supermassive Black Hole Masses: Implications for Hydrostatic Equilibrium and Dynamical Modelling in a Sample of Early-Type Galaxies
Key among these assumptions is that of hydrostatic equilibrium.
Hydrostatic Gas Constraints on Supermassive Black Hole Masses: Implications for Hydrostatic Equilibrium and Dynamical Modelling in a Sample of Early-Type Galaxies
We would expect deviations from hydrostatic equilibrium most likely to manifest themselves in nonthermal pressure support (e.g.
Hydrostatic Gas Constraints on Supermassive Black Hole Masses: Implications for Hydrostatic Equilibrium and Dynamical Modelling in a Sample of Early-Type Galaxies
Despite these concerns for these two systems, it is unlikely that any deviations from hydrostatic equilibrium are restricted solely to the central bin, and deviations at larger radius should produce residuals in our fit to the temperature and density profiles and a systematically under-estimated stellar M/LJ ratio.
Hydrostatic Gas Constraints on Supermassive Black Hole Masses: Implications for Hydrostatic Equilibrium and Dynamical Modelling in a Sample of Early-Type Galaxies
As we discuss in § 8.3, the good fits to these profiles at larger radii, combined with reasonable M/LJ ratios for each galaxy in fact suggest that hydrostatic equilibrium is a reasonable approximation.
Hydrostatic Gas Constraints on Supermassive Black Hole Masses: Implications for Hydrostatic Equilibrium and Dynamical Modelling in a Sample of Early-Type Galaxies
Stel lar M/LJ ratios In addition to the MBH measurements, our hydrostatic models also enabled us to constrain the stellar M/LJ ratios, under the assumption that the stellar mass follows light.
Hydrostatic Gas Constraints on Supermassive Black Hole Masses: Implications for Hydrostatic Equilibrium and Dynamical Modelling in a Sample of Early-Type Galaxies
We find good overall agreement between the measured M/LJ ratios and the models using a Kroupa or Chabrier IMF, suggesting that the gas is close to hydrostatic.
Hydrostatic Gas Constraints on Supermassive Black Hole Masses: Implications for Hydrostatic Equilibrium and Dynamical Modelling in a Sample of Early-Type Galaxies
Hydrostatic equilibrium Our results suggest that the hot ISM of these galaxies must be close to hydrostatic.
Hydrostatic Gas Constraints on Supermassive Black Hole Masses: Implications for Hydrostatic Equilibrium and Dynamical Modelling in a Sample of Early-Type Galaxies
The very small value of α dramatically illustrates that the mere existence of cavities does not immediately imply that the ISM is out of hydrostatic equilibrium in regions away from the cavities (which were excluded from our analysis).
Hydrostatic Gas Constraints on Supermassive Black Hole Masses: Implications for Hydrostatic Equilibrium and Dynamical Modelling in a Sample of Early-Type Galaxies
This point speaks to the recent criticisms of Diehl & Statler (2007), who argued that the lack of a correlation between the ellipticities of the X-ray and optical isophotes for a galaxy sample indicated the ubiquity of strong deviations from hydrostatic equilibrium.
Hydrostatic Gas Constraints on Supermassive Black Hole Masses: Implications for Hydrostatic Equilibrium and Dynamical Modelling in a Sample of Early-Type Galaxies
Notwithstanding the small amount of nonthermal pressure implied by our results, larger, albeit still modest, discrepancies have been reported between the mass inferred from stellar dynamics and hydrostatic X-ray methods at large scales in some systems (Shen & Gebhardt 2009; Romanowsky et al. 2008).
Hydrostatic Gas Constraints on Supermassive Black Hole Masses: Implications for Hydrostatic Equilibrium and Dynamical Modelling in a Sample of Early-Type Galaxies
It is unclear to what extent the discrepancies arise due to deviations from hydrostatic equilibrium in the studied systems and to what extent systematic errors in the stellar modelling play a role (especially those due to triaxiality and the uncertain inclination of the galaxies).
Hydrostatic Gas Constraints on Supermassive Black Hole Masses: Implications for Hydrostatic Equilibrium and Dynamical Modelling in a Sample of Early-Type Galaxies
This is more difficult to reconcile with deviations from hydrostatic equilibrium, unless the gas is globally outflowing within the central ∼20 kpc while maintaining a high X-ray luminosity and smooth-looking X-ray isophotes (H06).
Hydrostatic Gas Constraints on Supermassive Black Hole Masses: Implications for Hydrostatic Equilibrium and Dynamical Modelling in a Sample of Early-Type Galaxies
This would imply the bias on MBH is no larger than ±0.3 dex but, as discussed above, we expect the actual systematic errors due to the hydrostatic approximation to be far smaller in the present paper.
