Star formation in the local Universe from the CALIFA sample. I. Calibrating the SFR using integral field spectroscopy data. (2015)

Keywords : galaxies star formation - galaxies: spiral - galaxies: evolution - techniques: photometric - techniques: spectroscopic

Abstract:The star formation rate (SFR) is one of the main parameters used to analyze the evolution of galaxies through time. The need for recovering the light reprocessed by dust commonly requires the use of low spatial resolution far-infrared data. Recombination line luminosities provide an alternative, although uncertain dust-extinction corrections based on narrowband imaging or long-slit spectroscopy have traditionally posed a limit to their applicability. Integral field spectroscopy (IFS) is clearly the way to overcome this kind of limitation. We obtain integrated H{alpha}, ultraviolet (UV) and infrared (IR)-based SFR measurements for 272 galaxies from the CALIFA survey at 0.005<z<0.03 using single-band and hybrid tracers. We ...(more)

Astronomy and Astrophysics policies
The galaxies we studied are part of the CALIFA survey (Sanchez et al., 2012A&A...538A...8S). The CALIFA mother sample includes 939 galaxies of all types. A total of ~600 galaxies will be observed as part of CALIFA, using the Potsdam Multi-Aperture Spectrophotometer (PMAS) in the PPak mode mounted at the Calar Alto 3.5m telescope. The survey is described in detail in the presentation article (Sanchez et al., 2012A&A...538A...8S). The CALIFA spectra cover the range 3650-7500{AA} in two overlapping setups, one in the red (3745-7500{AA}) at a spectral resolution of R~850 (V500 setup) and one in the blue (3650-4840{AA}) at R~1650 (V1200 setup), where the resolutions quoted are those at the overlapping wavelength range ({lambda}~4500{AA}). For the purpose of deriving extinction-corrected H{alpha} luminosities, we make use of the V500 setup as we are interested in having both H{alpha}{lambda}4861{AA} and H{beta}{lambda}6563{AA} emission lines in the same observing range.
