Abstract:
We demonstrate how the Fundamental Manifold (FM) can be used to
cross-calibrate distance estimators even when those "standard candles"
are not found in the same galaxy. Such an approach greatly increases
the number of distance measurements that can be utilized to check for
systematic distance errors and the types of estimators that can be
compared. Here we compare distances obtained using Type Ia supernova
(SN Ia), Cepheids, surface brightness fluctuations, the luminosity of
the tip of the red giant branch, circumnuclear masers, eclipsing
binaries, RR Lyrae stars, and the planetary nebulae luminosity
functions. We find no significant discrepancies (differences are
<2σ) between distance methods, although differences at the ∼10%
level cannot yet be ruled out. The potential exists for significant
refinement because the data used here are heterogeneous B-band
magnitudes that will soon be supplanted by homogeneous, near-infrared
magnitudes. We illustrate the use of FM distances to (1) revisit the
question of the metallicity sensitivity of various estimators,
confirming the dependence of SN Ia distances on host galaxy
metallicity, and (2) provide an alternative calibration of H0 that
replaces the classical ladder approach in the use of extragalactic
distance estimators with one that utilizes data over a wide range of
distances simultaneously.
Description:
We utilize the NED 1-D database, which is a compilation of published
distances from a wide-ranging set of methods. To obtain the structural
parameters necessary to place a galaxy on the Fundamental Manifold
(FM), we search the HyperLeda database (Paturel et al. 2003,
Cat. VII/237). For a subset of the data, we also obtain an optical
color, (B-V)0, from the RC3 catalog (de Vaucouleurs et al. 1991,
Cat. VII/155) to investigate the role of color, and, by inference, of
differences in the stellar mass-to-light ratio, on a galaxy's
deviation from the FM.
