Chemical Complexity in Galaxies

TL;DR

This paper discusses how ALMA's imaging spectroscopy can reduce chemical complexity in galaxies by enabling detailed analysis of molecular line emissions at high resolution.

Contribution

It highlights the potential of high-resolution ALMA observations to better understand the chemical diversity in galaxies.

Findings

Molecular line emission varies significantly on kpc scales.

High-resolution imaging can define physical regions, reducing chemical complexity.

ALMA will enhance the ability to classify galactic regions based on molecular lines.

Abstract

ALMA will be able to detect a broad spectrum of molecular lines in galaxies. Current aperture synthesis observations indicate that the molecular line emission from galaxies is remarkably variable, even on kpc scales. Imaging spectroscopy at resolutions of an arcsecond or better will reduce the chemical complexity by allowing regions of physical conditions to be defined and classified.
