Candidate Periodically Variable Quasars from the Dark Energy Survey and the Sloan Digital Sky Survey
Yu-Ching Chen, Xin Liu, Wei-Ting Liao +62
Periodically variable quasars have been suggested as close binary supermassive black holes. We present a systematic search for periodic light curves in 625 spectroscopically confir…

Dark Energy Survey Identification of A Low-Mass Active Galactic Nucleus at Redshift 0.823 from Optical Variability
Hengxiao Guo, Colin J. Burke, Xin Liu +56
We report the identification of a low-mass AGN, DES J02180430, in a redshift galaxy in the Dark Energy Survey (DES) Supernova field. We select DES J02180430 as an…
