We present the first spatial clustering measurements of z~1, 24um-selected,star forming galaxies in the Great Observatories Origins Deep Survey (GOODS).The sample under investigation includes 495 objects in GOODS-South and 811objects in GOODS-North selected down to flux densities of f_24>20 uJy andz_AB<23.5 mag, for which spectroscopic redshifts are available. The medianredshift, IR luminosity and star formation rate (SFR) of the samples are z~0.8,L_IR~4.4 x 10^10 L_sun, and SFR~7.6 M_sun/yr, respectively. We measure theprojected correlation function w(r_p) on scales of r_p=0.06-10 h^-1 Mpc, fromwhich we derive a best fit comoving correlation length of r_0 = 4.0 +- 0.4 h^-1Mpc and slope of gamma=1.5 +- 0.1 for the whole f_24>20uJy sample aftercombining the two fields. We find indications of a larger correlation lengthfor objects of higher luminosity, with Luminous Infrared Galaxies (LIRGs,L_IR>10^11 L_sun) reaching r_0~5.1 h^-1 Mpc. This would imply that galaxieswith larger SFRs are hosted in progressively more massive halos, reachingminimum halo masses of ~3 x 10^12 M_sun for LIRGs. We compare our measurementswith the predictions from semi-analytic models based on the Millenniumsimulation. The variance in the models is used to estimate the errors in ourGOODS clustering measurements, which are dominated by cosmic variance. Themeasurements from the two GOODS fields are found to be consistent within theerrors. On scales of the GOODS fields, the real sources appear more stronglyclustered than objects in the Millennium-simulation based catalogs, if theselection function is applied consistently. This suggests that star formationat z~0.5-1 is being hosted in more massive halos and denser environments thancurrently predicted by galaxy formation models.[truncated]
