Beyond the Damped Random Walk: Multiband AGN Variability from SDSS to Rubin LSST
Izak Schmidlkofer, Zhirui Hu, Weixiang Yu +1
The flux variability of Active Galactic Nuclei (AGNs) is commonly modeled using the damped random walk (DRW), but increasingly rich multiband time-domain surveys motivate more flex…
Evidence for evolving Dark Energy from a new cosmic probe
Isaque Dutra, Colin J. Burke, Priyamvada Natarajan +1
The CDM concordance cosmological model provides a remarkably successful description of the formation and evolution of structure in the Universe. However, a growing discrepancy b…
Examining AGN UV/Optical Variability Beyond the Simple Damped Random Walk. II. Insights from 22 Years Observations of SDSS, PS1 and ZTF
Weixiang Yu, Gordon T. Richards, John J. Ruan +3
A damped random walk (DRW) process is often used to describe the temporal UV/optical continuum variability of active galactic nuclei (AGN). However, recent investigations have show…
Preliminary census of galaxies in the LISA localisation volume: I. Searching for LISA candidate massive black hole binary merger hosts using Sloan Digital Sky Survey photometry
Carolyn L. Drake, Jessie Runnoe, Aaron Stemo +6
With the launch of the Laser Interferometer Space Antenna (LISA), we will be able to estimate the sky position, luminosity distance (d), chirp mass, and mass ratio for detect…
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…
