SED modelling of LEGA-C & HST massive gal.

Combining stellar kinematic data from the Large Early Galaxy Astrophysics Census (LEGA-C) survey with structural parameters measured from deep Hubble Space Telescope imaging, we obtain a sample of 1419 massive (log(M_*_/M_{sun}_)>10.5) galaxies that span a wide range in morphology, star formation activity, and environment, and therefore is representative of the massive galaxy population at z~0.8.

We find that quiescent and star-forming galaxies occupy the parameter space of the g-band FP differently and thus have different distributions in the dynamical mass-to-light ratio (M_dyn_/L_g_), largely owing to differences in the stellar age and recent star formation history, and to a lesser extent, the effects of dust attenuation. In contrast, we show that both star-forming and quiescent galaxies lie on the same mass FP at z~0.8, with a comparable level of intrinsic scatter about the plane.
