Quantifying the Active Galactic Nuclei Fraction in Cosmic Voids via Mid-Infrared Variability
Anish S. Aradhey, Anca Constantin, Michael S. Vogeley +1
Observations and theoretical simulations suggest that the large scale environment plays a significant role in how galaxies form and evolve and, in particular, whether and when gala…
Investigating Non-linear and Stochastic Hard X-ray Variability of Active Galactic Nuclei using Recurrence Analysis
R. A. Phillipson, M. S. Vogeley, P. T. Boyd
We present results of recurrence analysis of 46 active galactic nuclei (AGN) using light curves from the 157-month catalog of the Swift Burst Alert Telescope (BAT) in the 14-150 ke…
HST /COS Lyman-alpha Absorbers in Cosmic Voids
William E. Watson, Michael S. Vogeley
We investigate the spatial distribution of Lyman- (Ly ) absorbers within cosmic voids. We create a catalogue of cosmic voids in Sloan Digital Sky Survey Data Release 7 (SDSS…
Examining AGN UV/optical Variability Beyond the Simple Damped Random Walk
Weixiang Yu, Gordon T. Richards, Michael S. Vogeley +2
We present damped harmonic oscillator (DHO) light-curve modeling for a sample of 12,714 spectroscopically confirmed quasars in the Sloan Digital Sky Survey Stripe 82 region. DHO is…
Properties of a Previously Unidentified Instrumental Signature in that was Confused for AGN Variability
Jackeline Moreno, Rachel Buttry, John O'Brien +3
The satellite potentially provides the highest precision photometry of active galactic nuclei (AGN) available to investigate short-timescale optical variability.…
Complex Variability of Kepler AGN Revealed by Recurrence Analysis
R. A. Phillipson, P. T. Boyd, A. P. Smale +1
The advent of new time domain surveys and the imminent increase in astronomical data expose the shortcomings in traditional time series analysis (such as power spectra analysis) in…
