The Regulation of Galaxy Growth along the Size-Mass Relation by Star Formation, as Traced by H alpha in KMOS3D Galaxies at 0.7 less than or similar to z less than or similar to 2.7
We present half-light sizes measured from H-alpha emission tracing star formation in 281 star-forming galaxies from the KMOS3D survey at 0.7 less than or similar to z less than or similar to 2.7. Sizes are derived by fitting 2D exponential disk models, with bootstrap errors averaging 20%. H-alpha sizes are a median (mean) of 1.19 (1.26) times larger than those of the stellar continuum-which, due to radial dust gradients, places an upper limit on the growth in stellar size via star...[Show more]
