| الوصف: | We have derived the bivariate luminosity function for the far ultraviolet (1530˚A) and far infrared (60 µm). We used matched GALEX and IRAS data, and redshifts from NED and PSC-z. We have derived a total star formation luminosity function φ(Ltot), with Ltot = LFUV + LFIR. Using these, we determined the cosmic “star formation rate ” function and density for the local universe. The total SFR function φ(Ltot) is fit very well by a log-normal distribution over five decades of luminosity. We find that the bivariate luminosity function φ(LFUV, LFIR) shows a bimodal behavior, with LFIR tracking LFUV for LTOT < 10 10 L⊙, and LFUV saturating at ∼ 10 10 L⊙, while LTOT ∼ LFIR for higher luminosities. We also calculate the SFR density and compare it to other measurements.
