The discovery of the first “changing look” quasar: new insights into the physics and phenomenology of active galactic nuclei
Stephanie M. LaMassa,Sabrina Cales,Sabrina Cales,E. C. Moran,Adam D. Myers,Gordon T. Richards,Michael Eracleous,Timothy M. Heckman,Luigi C. Gallo,C. Megan Urry +9 more
TL;DR: The most distant active galactic nucleus (AGN) was observed to have undergone such a dramatic change between 2000 and 2010 as discussed by the authors, which is the most distant AGN yet observed.

The Discovery of the First "Changing Look" Quasar: New Insights into the Physics & Phenomenology of AGN
Stephanie M. LaMassa,Sabrina Cales,E. C. Moran,Adam D. Myers,Gordon T. Richards,Michael Eracleous,Timothy M. Heckman,Luigi Gallo,C. Meg Urry +8 more
TL;DR: In this article, it was shown that the AGN flux dropped by a factor of 6 between 2000 and 2010 while the broad H$\alpha$ emission faded and broadened.
