Black hole and neutron star X-ray binary systems routinely show quasi-periodic oscillations
(QPOs) in their X-ray flux. Despite being strong, easily measurable signals, their physical …

Luminous accreting stellar mass and supermassive black holes produce power–law
continuum X-ray emission from a compact central corona. Reverberation time lags occur …

High-throughput experimental methods in neuroscience have led to an explosion of
techniques for measuring complex interactions and multi-dimensional patterns. However …

Neural oscillations are ubiquitous across recording methodologies and species, broadly
associated with cognitive tasks, and amenable to computational modelling that investigates …

Accretion disks around supermassive black holes in active galactic nuclei produce
continuum radiation at ultraviolet and optical wavelengths. Physical processes in the …

As telescopes, detectors, and computers grow ever more powerful, the volume of data at the
disposal of astronomers and astrophysicists will enter the petabyte domain, providing …

This paper describes the design and implementation of stingray, a library in Python built to
perform time series analysis and related tasks on astronomical light curves. Its core …

The author presents a model for variability of the flux and polarization of blazars in which
turbulent plasma flowing at a relativistic speed down a jet crosses a standing conical shock …

We review some practical aspects of measuring the amplitude of variability in 'red noise'light
curves typical of those from active galactic nuclei (AGN). The quantities commonly used to …

We model the time variability of∼ 9000 spectroscopically confirmed quasars in SDSS Stripe
82 as a damped random walk (DRW). Using 2.7 million photometric measurements …
