Abstract:
Dusty high-z galaxies are extreme objects with high star formation
rates (SFRs) and luminosities. Characterising the properties of this
population and analysing their evolution over cosmic time is key to
understanding galaxy evolution in the early Universe.
We select a sample of high-z dusty star-forming galaxies (DSFGs) and
evaluate their position on the main sequence (MS) of star-forming
galaxies, the well-known correlation between stellar mass and SFR. We
aim to understand the causes of their high star formation and quantify
the percentage of DSFGs that lie above the MS.
We adopted a multi-wavelength approach with data from optical to
submillimetre wavelengths from surveys at the North Ecliptic Pole
(NEP) to study a submillimetre sample of high-redshift galaxies.
Two submillimetre selection methods were used, including: sources
selected at 850um with the Sub-millimetre Common-User Bolometer Array
2) SCUBA-2 instrument and Herschel-Spectral and Photometric Imaging
Receiver (SPIRE) selected sources (colour-colour diagrams and 500um
risers), finding that 185 have good multi-wavelength coverage.
The resulting sample of 185 high-z candidates was further studied by
spectral energy distribution (SED) fitting with the CIGALE fitting
code. We derived photometric redshifts, stellar masses, SFRs, and
additional physical parameters, such as the infrared luminosity and
active galactic nuclei (AGN) contribution.
We find that the Herschel-SPIRE selected DSFGs generally have higher
redshifts (z=2.57+0.08-0.09) than sources that are selected solely
by the SCUBA-2 method (z=1.45+0.21-0.06). We find moderate SFRs
(797+108-50M_☉/yr), which are typically lower than those
found in other studies. We find that the different results in the
literature are, only in part, due to selection effects, as even in the
most extreme cases, SFRs are still lower than a few thousand solar
masses per year. The difference in measured SFRs affects the position
of DSFGs on the MS of galaxies; most of the DSFGs lie on the MS
(60%). Finally, we find that the star formation efficiency (SFE)
depends on the epoch and intensity of the star formation burst in the
galaxy; the later the burst, the more intense the star formation. We
discuss whether the higher SFEs in DSFGs could be due to mergers.
