ABSTRACT We present the radial gas-phase, mass-weighted metallicity profiles and gradients of TNG50 star-forming galaxy population measured at redshifts z = 0–3. investigate redshift evolution examine relations between gradient (negative) steepness properties. find that are predominantly negative all redshifts, although we observe significant diversity among these gradients. determine galaxies ...

We present a model for the CO molecular line emission from high redshift Submillimeter Galaxies (SMGs). By combining hydrodynamic simulations of gas rich galaxy mergers with the polychromatic radiative transfer code, SUNRISE, and the 3D non-LTE molecular line radiative transfer code, TURTLEBEACH, we show that if SMGs are typically a transient phase of major mergers, their observed compact CO sp...
