The FMOS-COSMOS Survey: Properties of dark matter halos of main-sequence star-forming galaxies at z~1.6

We investigate the properties of dark matter halos that contain "main-sequence" star-forming galaxies at 1.43<z<1.74 using the FMOS-COSMOS survey. The projected correlation function is measured for 516 galaxies down to stellar mass of 10^9.57 M_⦿ and SFR~15 M_⦿ yr^-1, for which the Hα emission line is detected. We find that these galaxies live in halos of M_h=5×10¹² M_⦿ on average, which will likely become present-day halos equivalent to the typical mass scale of galaxy groups. We then constrain the stellar-to-halo mass ratio at M_h<10¹² M_⦿, finding a systematically lower mass ratio than those measured at higher masses.
