Rotation du trou noir sur lui-me\u0302me<\/b><\/p>\n

Avec son e\u0301quipe, l\u2019astrophysicienne a e\u0301tudie\u0301 la rotation du trou noir sur lui-me\u0302me a\u0300 partir du comportement de la matie\u0300re formant son disque d\u2019accre\u0301tion. Les chercheurs ont pour cela utilise\u0301 le rayonnement X de SgrA*, collecte\u0301 par le te\u0301lescope spatial Chandra, et le rayonnement radio gra\u0302ce au Very Large Array (VLA), au Nouveau-Mexique.<\/p>\n

Un phare de rayons X<\/b><\/p>\n

Leurs observations re\u0301ve\u0300lent que le trou noir tourne tre\u0300s vite sur lui-me\u0302me, a\u0300 60 % de la vitesse maximale autorise\u0301e par les lois de la physique. Or, cette vitesse constitue une re\u0301serve d\u2019e\u0301nergie conside\u0301rable si un nuage de gaz ou une e\u0301toile venait a\u0300 s\u2019e\u0301garer a\u0300 proximite\u0301… SgrA* transformerait alors cette matie\u0300re en puissants jets d\u2019e\u0301nergie. Jusqu\u2019ici endormi, il se mettrait a\u0300 briller tel un phare de rayons X dans la galaxie.<\/p>\n
