The nature of gas and stars in the circumnuclear regions of AGN: a chemical approach

TL;DR

This paper investigates the chemical composition of gas and stars near galaxy nuclei, using various techniques to compare different galaxy types and understand the influence of nuclear activity.

Contribution

It presents initial results on chemical abundances in circumnuclear regions across galaxy classes, employing multiple estimation techniques.

Findings

Chemical abundances vary with galaxy activity level

Different techniques yield consistent abundance estimates

Initial results suggest links between chemical properties and nuclear activity

Abstract

Aim of this communication is to describe the first results of a work-in-progress regarding the chemical properties of gas and stars in the circumnuclear regions of nearby galaxies. Different techniques have been employed to estimate the abundances of chemical elements in the gaseous and stellar components of nuclear surroundings in different classes of galaxies according to the level of activity of the nucleus (normal or passive, star forming galaxies and AGNs).
