title: Merger-free AGN-hosts with GALFIT

description: History

This repository contains the data released in the paper "Structural Decomposition of Merger-Free Galaxies Hosting Luminous AGNs" (DOI to follow on publication).

We release GALFIT photometric fitting of bulgeless galaxies hosting luminous, Type 1 AGN imaged with the Hubble Space Telescope.
