Mapping the diffuse interstellar bands <i>λ</i>5780 and <i>λ</i>6284 in the luminous infrared galaxy merger NGC 6240 Open
Context. Diffuse interstellar bands (DIBs) are faint absorption features of a generally unknown origin. Observational constraints on their carriers have been provided in the vast majority of the cases thanks to observations in our Galaxy. …
