Inferring Stellar Densities with Flexible Models I: The Distribution of RR Lyrae in the Milky Way with DR3

Madeline Lucey, Cecilia Mateu, Adrian Price-Whelan +3

Understanding the formation and evolutionary history of the Milky Way requires detailed mapping of its stellar components, which preserve fossil records of the Galaxy's assembly th…

Active galactic nuclei do not exhibit strictly sinusoidal brightness variations

Kareem El-Badry, David W. Hogg, Hans-Walter Rix

Periodic variability in active galactic nuclei (AGN) light curves has been proposed as a signature of close supermassive black hole (SMBH) binaries. Recently, 181 candidate SMBH bi…

The Milky Way's circular velocity curve measured using element abundance gradients

Danny Horta, Adrian M. Price-Whelan, Sergey E. Koposov +4

Spectroscopic surveys now supply precise stellar label measurements such as element abundances for large samples of stars throughout the Milky Way. These element abundances are kno…

Sloan Digital Sky Survey-V: Pioneering Panoptic Spectroscopy

Juna A. Kollmeier, Hans-Walter Rix, Conny Aerts +217

The Sloan Digital Sky Survey-V (SDSS-V) is pioneering panoptic spectroscopy: it is the first all-sky, multi-epoch, optical-to-infrared spectroscopic survey. SDSS-V is mapping the s…

Identification of 30,000 White Dwarf-Main Sequence binaries candidates from Gaia DR3 BP/RP(XP) low-resolution spectra

Jiadong Li, Yuan-Sen Ting, Hans-Walter Rix +5

White dwarf-main sequence (WDMS) binary systems are essential probes for understanding binary stellar evolution and play a pivotal role in constraining theoretical models of variou…
