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…
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…
Data-driven Dynamics with Orbital Torus Imaging: A Flexible Model of the Vertical Phase Space of the Galaxy
Adrian M. Price-Whelan, Jason A. S. Hunt, Danny Horta +4
The vertical kinematics of stars near the Sun can be used to measure the total mass distribution near the Galactic disk and to study out-of-equilibrium dynamics. With contemporary…
Orbital Torus Imaging: Acceleration, density, and dark matter in the Galactic disk measured with element abundance gradients
Danny Horta, Adrian M. Price-Whelan, David W. Hogg +5
Under the assumption of a simple and time-invariant gravitational potential, many Galactic dynamics techniques infer the Milky Way's mass and dark matter distribution from stellar…
Finding, characterizing and classifying variable sources in multi-epoch sky surveys: QSOs and RR Lyrae in PS1 3 data
Nina Hernitschek, Edward F. Schlafly, Branimir Sesar +14
In area and depth, the Pan-STARRS1 (PS1) 3 survey is unique among many-epoch, multi-band surveys and has enormous potential for all-sky identification of variable sources. PS1 h…
Constraining the Milky Way potential with a 6-D phase-space map of the GD-1 stellar stream
Sergey E. Koposov, Hans-Walter Rix, David W. Hogg
The narrow GD-1 stream of stars, spanning 60 deg on the sky at a distance of ~10 kpc from the Sun and ~15 kpc from the Galactic center, is presumed to be debris from a tidally disr…
