Dark Energy Survey Year 6 Results: Photometric Data Set for Cosmology

K. Bechtol, I. Sevilla-Noarbe, A. Drlica-Wagner +103

We describe the photometric data set assembled from the full six years of observations by the Dark Energy Survey (DES) in support of static-sky cosmology analyses. DES Y6 Gold is a…

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…

Discovery of a Candidate Binary Supermassive Black Hole in a Periodic Quasar from Circumbinary Accretion Variability

Wei-Ting Liao, Yu-Ching Chen, Xin Liu +68

Binary supermassive black holes (BSBHs) are expected to be a generic byproduct from hierarchical galaxy formation. The final coalescence of BSBHs is thought to be the loudest gravi…

Two Ultra-Faint Milky Way Stellar Systems Discovered in Early Data from the DECam Local Volume Exploration Survey

S. Mau, W. Cerny, A. B. Pace +56

We report the discovery of two ultra-faint stellar systems found in early data from the DECam Local Volume Exploration survey (DELVE). The first system, Centaurus I (DELVE J1238-40…
