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, L₁₅₀, as a star-formation rate (SFR) tracer, which is unaffected by dust extinction.
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 L₁₅₀ for the cross-matched sources and compare it with the total infrared (IR) luminosity, L_IR, and various SFR tracers.
Results. We find a tight linear correlation between log L₁₅₀ and log L_IR for star-forming galaxies, with a slope of 1.37. The median q^IR value (defined as the logarithm of the L_IR to L₁₅₀ ratio) and its rms scatter of our main sample are 2.14 and 0.34, respectively. We also find that log L₁₅₀ correlates tightly with the logarithm of SFR derived from three different tracers, i.e., SFR_Hα based on the Hα line luminosity, SFR₆₀ based on the rest-frame 60 µm luminosity and SFR_IR based on L_IR, with a scatter of 0.3dex. Our best-fit relations between L₁₅₀ and these SFR tracers are, logL₁₅₀(L_☉)=1.35(±0.06)xlogSFR_Hα(M_☉/yr)+3.20(±0.06), logL₁₅₀(L_☉)=1.31(±0.05)xlogSFR₆₀(M_☉/yr)+3.14(±0.06), and logL₁₅₀(L_☉)=1.37(±0.05)xlogSFR_IR(M_☉/yr)+3.09(±0.05), which show excellent agreement with each other.
