Kinematics of zCOSMOS field galaxies up to z~1
Abstract
(abridged) The evolution of the B-band Tully Fisher relation (TFR) and of the stellar mass TFR up to z~1 is investigated using VIMOS tilted-slit spectra of 160 zCOSMOS galaxies. Furthermore, the stellar-to-halo-mass ratio (SHMR) as a function of mass is studied and compared to predictions from simulations. Interestingly, the derived SHMR is in agreement with abundance matching models, although using simple derivations of vcircular from vmax and of rvirial from r1/2. This shows that this new approach can be used complementary to abundance matching techniques to get new insights in the stellar content of dark matter halos for individual galaxies.
