First Detection of Radio Polarization During Jet Formation in the Changing-Look AGN 1ES 1927+654
Onic I. Shuvo, Eileen T. Meyer, Sibasish Laha +10
We present a multiwavelength radio study of the changing-look AGN 1ES 1927+654 following its renewed X-ray brightening since mid-2022, combining VLBA imaging with multi-band and ti…
The emergence of X-ray emission lines during relativistic radio-jet formation in the changing-look active galactic nucleus 1ES 1927+654
Dev R. Sadaula, Sibasish Laha, Eileen T. Meyer +27
We present results from a comprehensive multi-wavelength monitoring campaign of the changing-look active galactic nucleus 1ES 1927+654 during the onset and evolution of a relativis…
Relativistic Jets and Winds in Radio-Identified Supermassive Black Hole Binary Candidates
Andrew G. Sullivan, Roger D. Blandford, Anna Synani +4
Supermassive black hole binary systems (SMBHBs) are thought to emit the recently discovered nHz gravitational wave background; however, not a single individual nHz source has been…
Demystifying flux eruptions: Magnetic flux transport in magnetically arrested disks
Jonatan Jacquemin-Ide, Mitchell C. Begelman, Beverly Lowell +3
Magnetically arrested disks (MADs) are a compelling model for explaining variability in low-luminosity active galactic nuclei (AGN), including horizon-scale outbursts like those ob…
Dissipation and particle acceleration at intermittent structures with velocity and magnetic shear: Interaction of Kelvin-Helmholtz and Drift-Kink instabilities
Tsun Hin Navin Tsung, Gregory R. Werner, Dmitri A. Uzdensky +1
We present two-dimensional (2D) particle-in-cell simulations of a magnetized, collisionless, relativistic pair plasma subjected to combined velocity and magnetic-field shear, a sce…
Magnetic Pressure Dominance Stabilizes AGN Disks Against Gravitational Instability
Hannalore J. Gerling-Dunsmore, Mitchell C. Begelman, Jacob B. Simon +1
Magnetic effects have long been considered a possible factor in stabilizing the outer regions of active galactic nuclei (AGN) accretion disks against gravitational instability (GI)…
