Abstract:
More luminous Type Ia supernovae prefer less massive hosts and regions
of higher star formation. This correlation is inverted during
width-color-luminosity light-curve standardization resulting in
step-like biases of distance measurements with respect to host
properties. Using the PMAS/PPak Integral-field Supernovahosts
COmpilation (PISCO) supernova host sample and Sloan Digital Sky
Survey, Galaxy Evolution Explorer, and Two Micron All Sky Survey
photometry, we compare host stellar mass and specific star-formation
rate (sSFR) from different observation methods, including local versus
global, and fitting techniques to measure their impact on the host
step biases. Mass-step measurements for all our mass samples are
consistent within a 1σ significance from -0.03±0.02mag to
-0.04±0.02mag. Including or excluding UV information had no effect
on measured mass-step size or location. sSFR step sizes are more
significant than mass-step measurements and varied from 0.05±0.03mag
(Hα) and 0.06±0.02mag (UV) for a 51 host sample. The sSFR step
location is influenced by the mass sample used to normalize star
formation and by sSFR tracer choice. The step size is reduced to
0.04±0.03mag when using all available 73 hosts with Hα
measurements. This 73 PISCO host subsample overall lacked a clear step
signal, but here we are searching for whether different choices of
mass or sSFR estimation can create a step signal. We find no evidence
that different observation or fitting techniques choices can create a
distance measurement step in either mass or sSFR.
Description:
We consider 319 galaxies observed as part of the PMAS Integral-field
SN hosts COmpilation (PISCO; Galbany+ 2018, J/ApJ/855/107). These
observations were complemented by optical ugriz photometry from the
SDSS, NIR JHKs photometry from the Two Micron All Sky Survey (2MASS),
and UV photometry from the Galaxy Evolution Explorer (GALEX).
PISCO is a compilation of SN host galaxies observed with integral
field unit spectroscopy using the same instrument, the Potsdam
Multi-Aperture Spectrophotometer (PMAS)/PMAS fiber PAcK (PPak),
mounted to the 3.5m Calar Alto telescope.
We also used the SALT2 output fits for 30 unpublished SNe Ia from
Carnegie Supernova Project II (CSPII; Suntzeff et al., in preparation)
