Dust correction factors over 0 < z < 3 in massive star-forming galaxies derived from a stacking analysis of Herschel data.

OTEO I.

Abstract (from CDS):

We use a stacking analysis in Herschel/PACS to study the accuracy of several dust-correction factors that are typically employed to estimate the total star-formation rate (SFR) of high-redshift, massive, star-forming (SF) galaxies. We also analyze what stacking suggests about the relation between SFR and stellar mass and the redshift evolution of the specific SFR (sSFR=SFR/M*). We find that the dust properties of massive SF galaxies evolve with redshift, that is, galaxies at z∼2-3 are more attenuated than at z∼1 for a given UV continuum slope and stellar mass. As a consequence, a single IRX-β or dust-mass relation cannot be used to recover the total SFR of massive SF galaxies at 0≲z≲3. This might have implications for studies at higher redshifts, where a single IRX-β relation derived for local starbursts is usually assumed to be valid. However, we find evidence that the local relations might be valid at least up to z ∼1, where bluer and less massive galaxies can be detected through stacking. The spectral energy distribution fitting procedure with stellar population templates gives overestimated values (about 0.3-0.5dex in logSFR) of the dust-corrected SFR at all redshifts studied here. We find that the slope of the main-sequence of star formation is flatter than previously found in massive galaxies with log(M*/M☉≥10, and the redshift evolution of the sSFR reported in previous works in massive galaxies is well recovered.

within arcsec The VizieR photometry tool allows for easy visualization of photometry points extracted around the Simbad position from photometry-enabled catalogues in VizieR.
The search radius has to be specified by the user. It is currently limited to a maximum of 30 arcsec. It depends mostly on the precision or quality of the coordinates (SIMBAD and VizieR catalogs), the resolution of the images from which the sources were extracted, source extent, and source crowding.
Suggestions are: crowded field: 0.5 to 1.5 arcsec, 3 arcsec otherwise; uncertain coordinates (SIMBAD quality E or coordinates without reference): 5 to 30 arsec (risky!). sed-help-icon
