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…
Magnetic field transport in compact binaries
Nicolas Scepi, Geoffroy Lesur, Guillaume Dubus +1
Dwarf novae (DNe) and low mass X-ray binaries (LMXBs) show eruptions that are thought to be due to a thermal-viscous instability in their accretion disk. These eruptions provide co…
