The Twentieth Data Release of the Sloan Digital Sky Survey: First All-Sky BOSS Spectra, eROSITA-SDSS-V Mapper Coordinated Observations, and a Preview of the Local Volume Mapper
SDSS Collaboration, Mojgan Aghakhanloo, David Aguilar +273
This paper presents the twentieth data release (DR20) from the Sloan Digital Sky Survey, the third data release of its fifth generation (SDSS-V). SDSS-V is a panoptic spectroscopy…
Epicyclic Density Variations in the Indus Stellar Stream
Yong Yang, Geraint F. Lewis, Ting S. Li +12
Longitudinal density fluctuations observed in stellar streams can result from gravitational interactions with massive perturbers in the Milky Way, such as dark matter subhalos. Ana…
Chemodynamics of BoötesI with : Revised Velocity Gradient, Dark Matter Density, and Galactic Chemical Evolution Constraints
Nathan R. Sandford, Ting S. Li, Sergey E. Koposov +14
We combine new spectroscopic observations of the ultra faint dwarf galaxy (UFD) Boötes I (Boo I) from the Southern Stellar Stream Spectroscopic Survey () with 15 years…
The Nineteenth Data Release of the Sloan Digital Sky Survey
SDSS Collaboration, Gautham Adamane Pallathadka, Mojgan Aghakhanloo +210
Mapping the local and distant Universe is key to our understanding of it. For decades, the Sloan Digital Sky Survey (SDSS) has made a concerted effort to map millions of celestial…
Flipping of the tidal tails of the Ophiuchus stream due to the decelerating Galactic bar
Yong Yang, Geraint F. Lewis, Denis Erkal +16
The Ophiuchus stellar stream presents a puzzle due to its complicated morphology, with a substructure perpendicular to the main track (spur), a broadened tail (fanning), and a shor…
Kinematics of Antlia 2 and Crater 2 from The Southern Stellar Stream Spectroscopic Survey (S5)
Alexander P. Ji, Sergey E. Koposov, Ting S. Li +15
We present new spectroscopic observations of the diffuse Milky Way satellite galaxies Antlia 2 and Crater 2, taken as part of the Southern Stellar Stream Spectroscopic Survey (S5).…
The age-metallicity structure of the Milky Way disc with APOGEE
J. Ted Mackereth, Jo Bovy, Ricardo P. Schiavon +1
The best way to trace back the history of star formation and mass assembly of the Milky Way disc is by combining chemical compositions, ages and phase-space information for a large…
