The models are based on simple ``scaling relations'' for discs, obtained in the framework of Cold Dark Matter models for galaxy formation, and were ``calibrated'' as to reproduce the properties of the Milky Way and of nearby discs (at redshift z~0). In this paper, we compare the predictions of our ``hybrid'' approach to galaxy evolution to observations at moderate and high redshift. We find that the models are in fairly good agreement with observations up to z~1, while some problems appear at higher redshift (provided there is no selection bias in the data); these discrepancies may suggest that galaxy mergers (not considered in this work) played a non negligible role at z>1. We also predict the existence of a ``universal'' correlation between abundance gradients and disc scalelengths, independent of redshift.", "revisions": [ { "version": "v1", "updated": "2001-02-26T17:41:09.000Z" } ], "analyses": { "keywords": [ "spiral galaxies", "galactic discs", "chemo-spectrophotometric evolution", "properties", "cold dark matter models" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 14, "language": "en", "license": "arXiv", "status": "editable", "inspire": 573759 } } }
