| Popis: | We present the first measurement of clustering properties of low mass galaxies with a stellar mass down to M_*~10^9 Msun at 11.3 show a large bias of b~7.2+-1.3 on scales up to \theta~100" or 3.1 comoving Mpc, while blue galaxies with 0.5~10^{10} Msun, we estimate a correlation length and bias to be r_0~4.5 h^{-1} Mpc and b=1.9-3.5, which are much larger than those of low mass (M_*~10^9-10^{10} Msun) galaxies. The comparison of our measurements with analytic CDM models constrains the properties of hosting dark halos, and indicates that the low mass galaxies would be progenitors of galaxies with a typical luminosity of L Comment: 15 pages, 11 figures, submitted to PASJ |
