Abstract:
Spitzer data at 24, 70, and 160um and ground-based Hα images are
analyzed for a sample of 189 nearby star-forming and starburst
galaxies to investigate whether reliable star formation rate (SFR)
indicators can be defined using the monochromatic infrared dust
emission centered at 70 and 160um. We compare recently published
recipes for SFR measures using combinations of the 24um and observed
Hα luminosities with those using 24um luminosity alone. From
these comparisons, we derive a reference SFR indicator for use in our
analysis. Linear correlations between SFR and the 70um and 160um
luminosity are found for L(70)≳1.4x1042erg/s and
L(160)≳2x1042erg/s, corresponding to SFR≳0.1-0.3M☉/yr, and
calibrations of SFRs based on L(70) and L(160) are proposed. Below
those two luminosity limits, the relation between SFR and 70um (160um)
luminosity is nonlinear and SFR calibrations become problematic. A
more important limitation is the dispersion of the data around the
mean trend, which increases for increasing wavelength.
Description:
We combine data from two Spitzer Legacy surveys, Local Volume Legacy
(LVL; Dale et al. 2009, Cat. J/ApJ/703/517; J. C. Lee et al.
2010AAS...21520205L 2010AAS...21520205L) and Spitzer Infrared Nearby Galaxies Survey
(SINGS; Kennicutt et al. 2003PASP..115..928K 2003PASP..115..928K), with the local
starburst galaxy sample of the Spitzer MIPS-GTO programs (Engelbracht
et al. 2008ApJ...685..678E 2008ApJ...685..678E) and the luminous infrared galaxies (LIRGs)
sample of Alonso-Herrero et al. (2006ApJ...650..835A 2006ApJ...650..835A).

Note (1): Galaxy name, as listed in Dale et al. (2007ApJ...655..863D 2007ApJ...655..863D), Dale et
al. (2009, Cat. J/ApJ/703/517), or Engelbracht et al.
(2008ApJ...685..678E 2008ApJ...685..678E).
Note (2): Distance, rescaled, where necessary, to H0=70km/s/Mpc, as reported
in Dale et al. (2007ApJ...655..863D 2007ApJ...655..863D), Kennicutt et al. (2008,
Cat. J/ApJS/178/247), and Engelbracht et al. (2008ApJ...685..678E 2008ApJ...685..678E).
Note (3): For the SINGS galaxies (marked as "S" in Column "r_RHa"), the reported
number is an average of the "high" and "low" oxygen abundance values
derived in J. Moustakas et al. (2010, Cat. J/ApJS/190/233, see
discussion in Calzetti et al. 2007ApJ...666..870C 2007ApJ...666..870C). For the LVL (Local
Volume Legacy) galaxies (marked as "L" in Column "r_RHa"), the
reported oxygen abundances are from Marble et al.
(2010ApJ...715..506M 2010ApJ...715..506M). For the other galaxies, oxygen abundances are
from a variety of literature sources, as reported in Engelbracht et
al. (2008ApJ...685..678E 2008ApJ...685..678E).
Note (4): When available, the preferred source is the RC3 catalog
(De Vaucouleurs et al. 1991, Cat. VII/155), as reported in NED.
Note (6): Star formation rate per unit area, derived from Equation (17), and
dividing by the area calculated from the ionized gas emission radius
of RHa. The ΣSFR of galaxies for which the Hα flux
information is missing (see last column of table) is marked as a lower
limit.
Note (7): Luminosity normalized to the ionized gas emission area, in units of
erg/s/kpc2.
