Towards DIB mapping in galaxies beyond 100 Mpc. A radial profile of the lambda 5780.5 diffuse interstellar band in AM1353-272 B
Thanks to MUSE on the ESO-VLT, the authors have been able to detect and resolve the absorption of diffuse interstellar bands (DIBs) from the interstellar medium (ISM) of two interacting galaxies known by the name of the Dentist’s Chair. This is the first time that DIBs are resolved in galaxies outside the Local Group. The radial profile of the DIBS decreases in correlation with extinction, as expected because the same behaviour is observed in the Milky Way. These observations open new means for studying the ISM of remote galaxies and quasars.
