Continuum variability in multi-epoch quasar spectra from the Sloan Digital Sky Survey
Minjin Kim, Suyeon Son, Luis C. Ho
We examine the continuum variability of active galactic nuclei (AGNs) by analyzing the multi-epoch spectroscopic data from the Sloan Digital Sky Survey. To achieve this, we utilize…

Probing the Physical Origin of the Balmer Decrement in the Broad-line Region of Nearby Active Galactic Nuclei via Spectral Variability
Suyeon Son, Minjin Kim, Luis C. Ho +1
To investigate the physical origin of the Balmer decrement in the broad-line region of active galactic nuclei (AGNs), we measure the temporal variability of the fluxes of the broad…

Temperature Profiles of Accretion Disks in Luminous Active Galactic Nuclei derived from Ultraviolet Spectroscopic Variability
Suyeon Son, Minjin Kim, Luis C. Ho
The characteristic timescale () of continuum variability of the accretion disk in active galactic nuclei (AGNs) is known to be related to the thermal timescale, which is predict…
