Abstract:
The emerging light from a galaxy is under the influence of its own
interstellar medium, as well as its spatial orientation. Considering a
sample of 2239 local spiral galaxies in optical (Sloan Digital Sky
Survey u, g, r, i, and z) and infrared bands (WISE W1, W1), we study
the dependency of the global intrinsic attenuation in spiral galaxies
on their morphologies, sizes, and spatial inclinations. Reddening is
minimal at the extremes of low mass and gas depletion and maximal in
galaxies that are relatively massive and metal-rich and still retain
substantial gas reserves. A principal component constructed from
observables that monitor galaxy mass, relative H i content to old
stars, and infrared surface brightness is strongly correlated with the
amplitude of obscuration. We determine both a parametric model for
dust obscuration and a nonparametric model based on the Gaussian
process formalism. An average dust attenuation curve is derived for
wavelengths between 0.36 and 4.5µm.
Description:
The sample for this study comprises 2239 spiral galaxies with
SDSS-DR12 optical photometry and WISE infrared photometry.
HI line width and flux measurements of sufficient quality are
provided by the All Digital HI catalog (ADHI) that has been assembled
in the context of the Cosmicflows program (Tully+ 2016, J/AJ/152/50)
and is available at the Extragalactic Distance Database (EDD) website
and/or the Arecibo Legacy Fast ALFA Survey (ALFALFA; Haynes et al.
2011, J/AJ/142/170 and 2018, J/ApJ/861/49).
