Abstract:
We present calibrations for star formation rate (SFR) indicators in
the ultraviolet, mid-infrared, and radio-continuum bands, including
one of the first direct calibrations of 150MHz as an SFR indicator.
Our calibrations utilize 66 nearby star-forming galaxies with
Balmer-decrement-corrected Hα luminosities, which span five
orders of magnitude in SFR and have absolute magnitudes of
-24<Mr<-12. Most of our photometry and spectrophotometry are
measured from the same region of each galaxy, and our
spectrophotometry has been validated with SDSS photometry, so our
random and systematic errors are small relative to the intrinsic
scatter seen in SFR indicator calibrations. We find that the
Wide-field Infrared Space Explorer W4 (22.8µm), Spitzer 24µm,
and 1.4GHz bands have tight correlations with the
Balmer-decrement-corrected Hα luminosity, with a scatter of only
0.2dex. Our calibrations are comparable to those from the prior
literature for L* galaxies, but for dwarf galaxies, our calibrations
can give SFRs that are far greater than those derived from most
previous literature.
Description:
Our parent sample is star-forming galaxies with optical drift-scan
spectrophotometry from Moustakas & Kennicutt (2006, J/ApJS/164/81) and
Moustakas+ (2010, J/ApJS/190/233) that also have Sloan Digital Sky
Survey III optical imaging (SDSS-III; Aihara+ 2011ApJS..193...29A 2011ApJS..193...29A).
All of the galaxies in the sample have imaging at ultraviolet,
optical, near-infrared, and mid-infrared wavelengths, taken from
GALEX, the Swift UV/Optical Monitor Telescope, the Sloan Digital Sky
Survey III (SDSS-III), the Two Micron All Sky Survey (2MASS), the
Spitzer Space Telescope, and/or the Wide-field Infrared Space Explorer
(WISE).
Radio-continuum flux densities at 1.4GHz and 150MHz were determined
using multiple sets of archival data. Our principal source of 1.4GHz
flux densities is the NRAO VLA Sky Survey (NVSS, Condon+, 1998, VIII/65).
Our principal source of 150MHz flux densities is the TIFR GMRT Sky
Survey (TGSS), which has an angular resolution of ∼25". We used the
first alternative data release of the TGSS (TGSS ADR1; Intema+ 2017,
J/A+A/598/A78).
