Spectral similarities in galaxies through an unsupervised classification of spaxels

H Chambon, D Fraix-Burnet - Astronomy and Astrophysics-A&A, 2024 - aanda.org
Aims. We present the first unsupervised classification of spaxels in hyperspectral images of
individual galaxies. Classes identify regions by spectral similarity and thus take all the …
