#238 On the retroconversion of quiescent galaxies to an active state
https://www.eso.org/public/news/eso2409/ This observation seems to be the first? Of a quiescent galaxy spontaneously becoming active in real time? This might be a sign of new physics, matter creation or efficient catalysis. Reminder though that quiescentness is a continuum and that quiescent galaxies are never? fully quiescent. Regardless this is a new record.
