A Stochastic Model for the Luminosity Fluctuations of Accreting Black Holes
Brandon C. Kelly, Malgorzata Sobolewska, Aneta Siemiginowska
In this work we have developed a new stochastic model for the fluctuations in lightcurves of accreting black holes. The model is based on a linear combination of stochastic process…
Constraints on Black Hole Growth, Quasar Lifetimes, and Eddington Ratio Distributions from the SDSS Broad Line Quasar Black Hole Mass Function
Brandon C. Kelly, Marianne Vestergaard, Xiaohui Fan +3
We present an estimate of the black hole mass function (BHMF) of broad line quasars (BLQSOs) that self-consistently corrects for incompleteness and the statistical uncertainty in t…
Modeling the Time Variability of SDSS Stripe 82 Quasars as a Damped Random Walk
C. L. MacLeod, Ž. Ivezić, C. S. Kochanek +10
We model the time variability of ~9,000 spectroscopically confirmed quasars in SDSS Stripe 82 as a damped random walk. Using 2.7 million photometric measurements collected over 10…
Morphological classification of galaxies and its relation to physical properties
D. B. Wijesinghe, A. M. Hopkins, B. C. Kelly +2
We extend a recently developed galaxy morphology classification method, Quantitative Multiwavelength Morphology (QMM), to connect galaxy morphologies to their underlying physical p…
Submillimeter Variability and the Gamma-ray Connection in Fermi Blazars
Allison L. Strom, Aneta Siemiginowska, Mark A. Gurwell +1
We present multi-epoch observations from the Submillimeter Array (SMA) for a sample of 171 bright blazars, 43 of which were detected by Fermi during the first three months of obser…
