Time-varying double-peaked emission lines following the sudden ignition of the dormant galactic nucleus AT2017bcc

E. J. Ridley, M. Nicholl, C. A. Ward +35

We present a pan-chromatic study of AT2017bcc, a nuclear transient that was discovered in 2017 within the skymap of a reported burst-like gravitational wave candidate, G274296. It…
