The expected photometrical characteristics of high redshift spiral galaxies

TL;DR

This paper models how star formation and metallic enrichment in early spiral galaxies affect their colors through emission lines, using chemo-spectro-photometrical theories.

Contribution

It introduces a consistent theoretical approach to quantify the impact of emission lines on the color evolution of high redshift spiral galaxies.

Findings

Emission lines significantly alter galaxy colors at early stages.

Color variations depend on star formation and metallicity levels.

Models help interpret observations of distant spiral galaxies.

Abstract

The star formation and the subsequent metallic enrichment of spiral galaxies, occurring at the early phases of their evolution, produce emission lines whose contribution may change the colors of these objects. We have computed this contribution with consistent chemo-spectro-photometrical theoretical models in order to calculate the variations in the colors evolution.
