dc.description.abstract | <BR /> Aims: We aim to study the far-infrared radio correlation (FIRC) at 150 MHz in the local Universe (at a median redshift ⟨z⟩∼0.05) and improve the use of the rest-frame 150 MHz luminosity, L<SUB>150</SUB>, as a star-formation rate (SFR) tracer, which is unaffected by dust extinction. <BR /> Methods: We cross-match the 60 μm selected Revised IRAS Faint Source Survey Redshift (RIFSCz) catalogue and the 150 MHz selected LOFAR value-added source catalogue in the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) Spring Field. We estimate L<SUB>150</SUB> for the cross-matched sources and compare it with the total infrared (IR) luminosity, L<SUB>IR</SUB>, and various SFR tracers. <BR /> Results: We find a tight linear correlation between log L<SUB>150</SUB> and log L<SUB>IR</SUB> for star-forming galaxies, with a slope of 1.37. The median q<SUP>IR</SUP> value (defined as the logarithm of the L<SUB>IR</SUB> to L<SUB>150</SUB> ratio) and its rms scatter of our main sample are 2.14 and 0.34, respectively. We also find that log L<SUB>150</SUB> correlates tightly with the logarithm of SFR derived from three different tracers, i.e., SFR<SUB>Hα</SUB> based on the Hα line luminosity, SFR<SUB>60</SUB> based on the rest-frame 60 μm luminosity and SFR<SUB>IR</SUB> based on L<SUB>IR</SUB>, with a scatter of 0.3 dex. Our best-fit relations between L<SUB>150</SUB> and these SFR tracers are, log L<SUB>150</SUB> (L<SUB>☉</SUB>) = 1.35(±0.06) × log SFR<SUB>Hα</SUB> (M<SUB>☉</SUB> yr<SUP>-1</SUP>) + 3.20(±0.06), log L<SUB>150</SUB> (L<SUB>☉</SUB>) = 1.31(±0.05) × log SFR<SUB>60</SUB> (M<SUB>☉</SUB> yr<SUP>-1</SUP>) + 3.14(±0.06), and log L<SUB>150</SUB> (L<SUB>☉</SUB>) = 1.37 (±0.05) × log SFR<SUB>IR</SUB> (M<SUB>☉</SUB> yr<SUP>-1</SUP>) + 3.09(±0.05), which show excellent agreement with each other. | en_US |
