Magnetic flux inversion in a peculiar changing look AGN

Nicolas Scepi, Mitchell C. Begelman, Jason Dexter

We argue that the changing-look event in the active galactic nucleus 1ES 1927+654, followed by a dip of 3 orders of magnitude in the X-ray luminosity, is controlled by a change in…

QPOs in compact binaries from small scale eruptions in an inner magnetized disk

Nicolas Scepi, Mitchell C. Begelman, Jason Dexter

Dwarf novæ (DNe) and low mass X-ray binaries (LMXBs) are compact binaries showing variability on time scales from years to less than seconds. Here, we focus on explaining part of t…
