Polarization Angle Swings in Blazars Detected in the Millimeter-wave with the South Pole Telescope
A. Simpson, E. Anderes, A. J. Anderson +93
We present the first systematic search for electric vector position angle (EVPA) swings in the millimeter-wave (mm-wave) emission of blazars, using five years of observations from…

An X-ray and optical spectral study of the changing-look narrow-line Seyfert 1 2MASX J0413-0050
A. Vietri, A. Tortosa, D. IliÄ +12
Active galactic nuclei (AGN) showing dramatic spectral and flux variations, either due to changes in the accretion rate (changing-state, CS-AGN) of the supermassive black hole or i…

Flip-flop states in X-ray binaries and changing-state AGN
Thomas J. Maccarone, Jessie Runnoe, Gregoire Marcel +4
We show that the flip-flop transitions in X-ray binaries (rapid cycling between different spectral states which are sometimes seen near the global state transition) show a series o…
