Abstract:
We present a comparison of star formation rates (SFR) determined from
mid-infrared 7.7um polycyclic aromatic hydrocarbon (PAH) luminosity
[SFR(PAH)], from 1.4GHz radio luminosity [SFR(radio)], and from
far-ultraviolet luminosity [SFR(UV)] for a sample of 287 starburst
galaxies with z<0.5 having Spitzer IRS observations.
Description:
A summary of 243 starbursts with IRS spectra and determinations of
SFR(PAH) is given by Weedman & Houck (2008, Cat J/ApJ/686/127). To
increase substantially the sample of Spitzer starbursts, we have
extracted new IRS spectra from the archival data of two Spitzer Legacy
Programs (30742; PI: D. Schiminovich and 40539; PI: G. Helou).
Infrared flux densities are compared with the GALEX observed flux
densities in the ultraviolet at wavelengths 153nm (FUV) and 227nm
(NUV) (GALEX data used in this paper were those available in 2009
February at the MultiMission Archive at the Space Telescope Science
Institute (http://archive.stsci.edu/)) and with radio detections from
the FIRST survey (White et al. 1997, Cat. VIII/71) and from targeted
observations with the VLA (Condon et al. 2003, Cat. J/AJ/125/2411).

Note (1): the 276 objects SST24 are named
<[SW2009] SST24 JHHMMSS.ss+DDMMSS.s> in Simbad.
Note (2): Flags as follows:
h = SST24 name derives from discovery at 24um with Spitzer Space
Telescope surveys; source taken from summary in Weedman and Houck (2008,
Cat J/ApJ/686/127) where original discovery references are given.
i = Source taken from Spitzer Legacy program 30742 (D. Schiminovich, P.I.)
for sources within the SWIRE Lockman Hole Field that also have measured
fluxes from GALEX.
j = Source taken from Spitzer Legacy program 40539 (G. Helou, P.I.), a flux
limited sample from various Spitzer survey fields of sources with
fν(24um) greater than 5mJy.
k = Blue Compact Dwarf from Wu et al. (2006ApJ...639..157W 2006ApJ...639..157W).
Note (3): No entry means that the source was not included in any GALEX
observation.
Note (4): Fit with single gaussian on a linear continuum within rest wavelength
range 5.5um to 6.9um.
Note (5): Interpolated with a power law between flux densities in the GALEX
catalog measured with the FUV filter (134-179nm) and the NUV
filter (177-283nm).
Note (6): Observed with the VLA, usually within the FIRST survey, corrected
from observed frame to rest frame 1.4GHz by assuming a power law
spectrum of index α=-0.7.
Note (7): Star Formation rates computed as:
* log[SFR(PAH)]=log[νLν(7.7um)]-42.57 for
νLν(7.7um) the luminosity at the peak of the 7.7um
feature in ergs/s (10-7W) and SFR in M☉/yr;
* log[SFR(UV)]=log[νLν(FUV)]-43.26 for νLν(FUV)
in ergs/s (10-7W) and SFR in M☉/yr;
* log[SFR(radio)]=log[νLν(1.4GHz)]-37.07 for
νLν(1.4GHz) in ergs/s (10-7W) and SFR in M☉/yr
(log[νLν(L☉)]=log[νLν(ergs/s)]-33.59).
* Luminosity calculations use luminosity distances from E.L. Wright,
http://www.astro.ucla.edu/~wright/CosmoCalc.html, for
H0=71km/s/Mpc, ΩM=0.27 and ΩΛ=0.73.
