Why haven't the observed high-frequency QPOs been produced by (MHD) computer simulations of black hole accretion disks?
Robert V. Wagoner, Celia R. Tandon
We compare some predictions of Wagoner & Tandon (2021) with the results of the hydrodynamic and magnetohydrodynamic (MHD) simulations of Reynolds & Miller (2009). It appears that t…
Evolution of a Mode of Oscillation Within Turbulent Accretion Disks
Robert V. Wagoner, Celia R. Tandon
We investigate the effects of subsonic turbulence on a normal mode of oscillation [a possible origin of the high-frequency quasi-periodic oscillations (HFQPOs) within some black ho…
Confrontation of Observation and Theory: High Frequency QPOs in X-ray Binaries, Tidal Disruption Events, and Active Galactic Nuclei
Krista Lynne Smith, Celia R. Tandon, Robert V. Wagoner
We compile observations of high-frequency quasi-periodic oscillations (QPOs) around black holes, both stellar and supermassive, and compare their positions in the parameter space o…
Evidence for an Optical Low-frequency Quasi-Periodic Oscillation in the Kepler Light Curve of an Active Galaxy
Krista Lynne Smith, Richard F. Mushotzky, Patricia T. Boyd +1
We report evidence for a quasi-periodic oscillation (QPO) in the optical light curve of KIC 9650712, a narrow-line Seyfert 1 galaxy in the original Kepler field. After the developm…
Science-Driven Optimization of the LSST Observing Strategy
LSST Science Collaboration, Phil Marshall, Timo Anguita +102
The Large Synoptic Survey Telescope is designed to provide an unprecedented optical imaging dataset that will support investigations of our Solar System, Galaxy and Universe, acros…
Order out of Randomness : Self-Organization Processes in Astrophysics
Markus J. Aschwanden, Felix Scholkmann, William Bethune +13
Self-organization is a property of dissipative nonlinear processes that are governed by an internal driver and a positive feedback mechanism, which creates regular geometric and/or…
