Bravo Stéphane pour le spectre !

A noter aussi que Stéphane a publié un article dans l' Astronomie Magazine du mois de Juillet-Août 2016 qui concerne notre galaxie et la radio astronomie. Chapeau pour le travail !

Superbe Olivier ! J'ai du mal à suivre tant le niveau de maîtrise technique est élevé.
Que signifient les pics d'absorption vers 5900 A ?
Amicalement,
Michel
