Discovery of the Distant, Ultra-Faint Milky Way Satellite Aquarius IV with the Vera C. Rubin Observatory Early Data Preview 2
William Cerny, Aashay Pai, Alex Drlica-Wagner +16
We present the discovery of Aquarius IV (Rubin J22010234) -- the first ultra-faint Milky Way satellite to be identified using data from the Vera C. Rubin Observatory. This syste…
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
The paper describes the twentieth data release (DR20) of the Sloan Digital Sky Survey, providing over 3 million new optical spectra from the SDSS‑V Milky Way, Black Hole, and Local…
Deep Imaging of Grus II and Horologium II: Structure and Extent of Two Ultra-Faint Milky Way Satellites
Deepthi S. Prabhu, David J. Sand, Anirudh Chiti +29
We present deep, wide-field Magellan/Megacam imaging of the ultra-faint Milky Way (MW) satellites Grus II (Gru II) and Horologium II (Hor II), with the aim of deriving improved con…
The DECam MAGIC Survey: Uncovering the Tidal Tails of the Crater II Dwarf Galaxy
Kaia R. Atzberger, Andrew B. Pace, Nitya Kallivayalil +27
Crater II (CraII), a large and low-density dwarf spheroidal galaxy, has unusual observed properties that are difficult to reproduce in cold dark matter simulations. Ongoing tidal d…
SDSS-V LVM: Revealing the Physical and Chemical Structure of the Helix Nebula
R. Orozco-Duarte, J. E. Méndez-Delgado, J. A. Toalá +27
We present the first spatially contiguous study of the physical and chemical structure of the Helix Nebula (NGC~7293, PNG 036.1-57.1) based on integral-field spectroscopy from the…
Discovery and Spectroscopic Characterization of a Distant, Compact Milky Way Satellite in Gemini
K. Overdeck, W. Cerny, C. Y. Tan +27
We present the discovery of a compact Milky Way satellite in the constellation of Gemini. This system was discovered by cross-matching detections from two independent search algori…
