TL;DR

This paper introduces open-source web tools for interactive visualization of galaxy spectral and imaging data, enhancing accessibility and integration with astronomical archives.

Contribution

Development of modern, customizable web-based viewers for spectral and imaging data visualization using Quasar and Vue.js frameworks.

Findings

Interactive spectral and SED viewers with minimal server load

Compatibility with third-party tools like Aladin Lite

Easy embedding into astronomical web resources

Abstract

We present a set of open-source web tools for visualization of spectral and imaging data, which we use in the second Reference Catalogue of Spectral Energy Distributions of galaxies RCSEDv2 (https://rcsed2.voxastro.org/). Using modern web frameworks Quasar and Vue.js we developed interactive viewers to visualize spectra and SEDs of galaxies and the diagrams presenting emission line ratios determined from the analysis of their spectra (BPT diagrams). The viewers are built in Javascript which puts a minimum load on the server side while providing full interactivity for the user. The use of modern web frameworks provides full customization making the viewers easily embeddable into web-sites of astronomical archives and databases. It also provides compatibility with popular third-party web-tools such as Aladin Lite.
