The Spatially Resolved Star Formation Law From Integral Field Spectroscopy: Virus-P Observations Of NGC 5194
We investigate the relation between the star formation rate (SFR) surface density (Sigma(SFR)) and the mass surface density of gas (Sigma(gas)) in NGC 5194 (a.k.a. M51a, Whirlpool Galaxy). Visible Integral field Replicable ...
The Black Hole Mass, Stellar Mass-To-Light Ratio, And Dark Halo In M87
We model the dynamical structure of M87 (NGC4486) using high spatial resolution long-slit observations of stellar light in the central regions, two-dimensional stellar light kinematics out to half of the effective radius, ...
A Quintet Of Black Hole Mass Determinations
We report five new measurements of central black hole masses based on Space Telescope Imaging Spectrograph and Wide Field Planetary Camera 2 observations with the Hubble Space Telescope (HST) and on axisymmetric, three-integral, ...
Hydrostatic Gas Constraints On Supermassive Black Hole Masses: Implications For Hydrostatic Equilibrium And Dynamical Modeling In A Sample Of Early-Type Galaxies
We present new mass measurements for the supermassive black holes (SMBHs) in the centers of three early-type galaxies. The gas pressure in the surrounding, hot interstellar medium (ISM) is measured through spatially resolved ...
Dark Matter Scaling Relations And The Assembly Epoch Of Coma Early-Type Galaxies
Axisymmetric, orbit-based dynamical models are used to derive dark matter scaling relations for Coma early-type galaxies. From faint to bright galaxies, halo core radii and asymptotic circular velocities increase. Compared ...
The M-Sigma And M-L Relations In Galactic Bulges, And Determinations Of Their Intrinsic Scatter
We derive improved versions of the relations between supermassive black hole mass (MBH) and host-galaxy bulge velocity dispersion (sigma) and luminosity (L; the M-sigma and M-L relations), based on 49 M-BH measurements and ...
