Abstract:
We present new color-U* (mass-to-light ratio) models to convert
Wide-field Infrared Survey Explorer W1 fluxes into stellar masses. We
outline a range of possible star formation histories and chemical
evolution scenarios to explore the confidence limits of stellar
population models on the value of U*. We conclude that the greatest
uncertainties (around 0.1dex in U*) occur for the bluest galaxies
with the strongest variation in recent star formation. For high-mass
galaxies, the greatest uncertainty arises from the proper treatment of
bulge-disk separation in which to apply different U* relations
appropriate for those differing underlying stellar populations. We
compare our deduced stellar masses with those deduced from Spitzer
Space Telescope 3.6µm fluxes and stellar mass estimates in the
literature using optical photometry and different U* modeling. We find
the correspondence to be excellent, arguing that rest-frame near-IR
photometry is still more advantageous than other wavelengths.
Description:
The Spitzer Photometry and Accurate Rotation Curves (SPARC) data set
consists of high-quality HI rotation curves accumulated over the last
three decades of radio interferometry combined with deep near-IR
photometry from the Spitzer 3.6um IRAC camera.
WISE is a NASA 40cm IR space telescope launched into Sun-synchronous
polar orbit in 2009. Its primary mission was to survey the sky at the
mid-infrared bands of 3.4, 4.6, 12 and 22um.
The SPARC project depended on pointed observations from Spitzer. With
the termination of the Spitzer mission, future dynamical studies from
our team will use the all-sky data set from the WISE mission (II/311).
Fortunately, the WISE and Spitzer filters overlap in the near-IR.
