| | 9 | In the context of the wealth of recent work focusing on the contribution of |
| | 10 | discreet evolutionary processes to galaxy size growth, we aim to |
| | 11 | re-establish the importance of underlying cosmic evolution, examining how |
| | 12 | the radii of collapsed structures predicted by standard cosmology maps on to |
| | 13 | mass-size trends in the galaxy population. In particular, we find that |
| | 14 | trends in galactic radii can be seen as emerging from stellar mass content |
| | 15 | that varies strongly as a function of host structure properties (for |
| | 16 | physical reasons which we review), but that carries a characteristic |
| | 17 | specific angular momentum which remains an imprint of its host's. This |
| | 18 | interpretation is complementary to well known merger-based arguments, which |
| | 19 | it naturally incorporates as a limiting case, but includes and quantifies |
| | 20 | the roles of cooling, feedback and cosmology. |
