Probing the Origin of Changing-look Quasar Transitions with Chandra
Qian Yang, Paul J. Green, Chelsea L. MacLeod +9
Extremely variable quasars can also show strong changes in broad-line emission strength and are known as changing-look quasars (CLQs). To study the CLQ transition mechanism, we pre…
The long-term broad-line responsivity in MKN 110
D. Homan, A. Lawrence, M. Ward +7
We examine the long-term history of the optical spectrum of the extremely variable Active Galactic Nucleus (AGN) MKN 110. By combining various archival data with new data, we cover…
The Time Domain Spectroscopic Survey: Changing-Look Quasar Candidates from Multi-Epoch Spectroscopy in SDSS-IV
Paul J. Green, Lina Pulgarin-Duque, Scott F. Anderson +18
Active galactic nuclei (AGN) can vary significantly in their rest-frame optical/UV continuum emission, and with strong associated changes in broad line emission, on much shorter ti…
