Spatially-resolved Evolution of Galaxies

TL;DR

This review discusses the spatially-resolved properties of galaxies, emphasizing the importance of kpc-scale scaling relations derived from Integral Field Spectroscopy to understand galaxy formation and evolution.

Contribution

It highlights the significance of kpc-scale scaling relations obtained via IFS in linking local and global galaxy evolution processes.

Findings

Existence of kpc-scale scaling relations supports unified galaxy evolution models

IFS enables detailed study of spatial distribution of galaxy observables

Local scaling relations mirror global galaxy properties

Abstract

Projected in the sky, galaxies are spatially-resolved objects. To understand how they formed and evolve it is necessary to study the spatial distribution of their observables. In this review talk, we briefly describe some scaling relations used to understand the physical processes that drive galaxy evolution, in particular for disk-like star-forming galaxies. First, we explore the relations derived using integrated galactic properties, then we introduce the scaling relations at kpc scales derived using the technique called Integral Field Spectroscopy (IFS) for large samples of galaxies in the nearby Universe.The very existence of scaling relations at kpc scales is a strong evidence that any physical scenario that explains the observed global scaling relations must be able to also explain their local counterpart.
