| 英文摘要 | For the first time both H alpha and far-ultraviolet (FUV) observations from an HI-selected sample are used to determine the dust-corrected star formation rate density (SFRD: (rho)over dot) in the local Universe. Applying the two star formation rate indicators on 294 local galaxies, we determine log((rho)over dotH alpha) = -1.68(-0.05)(+0.13) [M(circle dot)yr(-1) Mpc(-3)] and log((rho)over dotFUV) = -1.71(-0.13)(+0.12) [M-circle dot yr(-1) Mpc(-3)]. These values are derived from scaling H alpha and FUV observations to the HI mass function. Galaxies were selected to uniformly sample the full HI mass (M-HI) range of the HI Parkes All-Sky Survey (M-HI similar to 10(7) to similar to 10(10.7) M-circle dot). The approach leads to relatively larger sampling of dwarf galaxies compared to optically selected surveys. The low HI mass, low luminosity, and low surface brightness galaxy populations have, on average, lower H alpha/FUV flux ratios than the remaining galaxy populations, consistent with the earlier results of Meurer. The near-identical H alpha-and FUV-derived SFRD values arise with the low H alpha/FUV flux ratios of some galaxies being offset by enhanced H alpha from the brightest and high mass galaxy populations. Our findings confirm the necessity to fully sample the HI mass range for a complete census of local star formation to include lower stellar mass galaxies which dominate the local Universe. |
