Abstract

We present the evolution of the luminosity-size and stellar mass-size relations of luminous ( L V ≳ 3.4 × 10 10 h L ☉ ) and massive ( M * ≳ 3 × 10 10 h M ☉ ) galaxies in the last ~11 Gyr. We use very deep near-infrared images of the Hubble Deep Field-South and the MS 1054-03 field in the J s , H , and K s bands from FIRES to retrieve the sizes in the optical rest frame for galaxies with z > 1. We combine our results with those from GEMS at 0.2 < z < 1 and SDSS at z ~ 0.1 to achieve a comprehensive picture of the optical rest-frame size evolution from z = 0 to 3. Galaxies are differentiated according to their light concentration using the Sérsic index n . For less concentrated objects, the galaxies at a given luminosity were typically ~3 ± 0.5 (±2 σ) times smaller at z ~ 2.5 than those we see today. The stellar mass-size relation has evolved less: the mean size at a given stellar mass was ~2 ± 0.5 times smaller at z ~ 2.5, evolving proportionally to (1 + z ) -0.40±0.06 . Simple scaling relations between dark matter halos and baryons in a hierarchical cosmogony predict a stronger (although consistent within the error bars) than observed evolution of the stellar mass-size relation. The observed luminosity-size evolution out to z ~ 2.5 matches well recent infall model predictions for Milky Way-type objects. For low- n galaxies, the evolution of the stellar mass-size relation would follow naturally if the individual galaxies grow inside out. For highly concentrated objects, the situation is as follows: at a given luminosity, these galaxies were ~2.7 ± 1.1 times smaller at z ~ 2.5 (or, put differently, were typically ~2.2 ± 0.7 mag brighter at a given size than they are today), and at a given stellar mass the size has evolved proportionally to (1 + z ) -0.45±0.10 .

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
