Boötes III is a Tidally Disrupting Ultra-Faint Dwarf Galaxy on an Eccentric Polar Orbit
Ting S. Li, Denis Erkal, Andrew B. Pace +20
We present updated systemic properties of the ultra-faint dwarf galaxy Boötes III from the Southern Stellar Stream Spectroscopic Survey (S). We identify 21 high-probability mem…
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…
: Tidal Disruption in Crater 2 and Formation of Diffuse Dwarf Galaxies in the Local Group
Guilherme Limberg, Alexander P. Ji, Ting S. Li +19
We present results of a spectroscopic campaign around the diffuse dwarf galaxy Crater 2 (Cra2) and its tidal tails as part of the Southern Stellar Stream Spectroscopic Survey ($S^5…
OzDES Reverberation Mapping of Active Galactic Nuclei: Final Data Release, Black-Hole Mass Results, & Scaling Relations
H. McDougall, T. M. Davis, Z. Yu +53
Over the last decade, the Australian Dark Energy (OzDES) collaboration has used Reverberation Mapping to measure the masses of high redshift supermassive black holes. Here we prese…
OzDES Reverberation Mapping Program: CIV lags from six years of data
A. Penton, H. McDougall, T. M. Davis +52
We present 29 successfully recovered CIV time lags in Active Galactic Nuclei from the complete Dark Energy Survey Reverberation Mapping campaign. The AGN in this sample span a reds…
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…
Sifting for a Stream: The Morphology of the Stellar Stream
Benjamin Cohen, Alexander P. Ji, Peter S. Ferguson +18
Stellar streams are sensitive laboratories for understanding the small-scale structure in our Galaxy's gravitational field. Here, we analyze the morphology of the stellar st…
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…
: New insights from deep spectroscopic observations of the tidal tails of the globular clusters NGC 1261 and NGC 1904
Petra Awad, Ting S. Li, Denis Erkal +22
As globular clusters (GCs) orbit the Milky Way, their stars are tidally stripped forming tidal tails that follow the orbit of the clusters around the Galaxy. The morphology of thes…
The Great Escape: Discovery of a nearby 1700 km/s star ejected from the Milky Way by Sgr A*
Sergey E. Koposov, Douglas Boubert, Ting S. Li +17
We present the serendipitous discovery of the fastest Main Sequence hyper-velocity star (HVS) by the Southern Stellar Stream Spectroscopic Survey (S5). The star S5-HVS1 is a $\sim…
Finding high-redshift strong lenses in DES using convolutional neural networks
C. Jacobs, T. Collett, K. Glazebrook +63
We search Dark Energy Survey (DES) Year 3 imaging data for galaxy-galaxy strong gravitational lenses using convolutional neural networks. We generate 250,000 simulated lenses at re…
Quasar Accretion Disk Sizes from Continuum Reverberation Mapping in the DES Standard Star Fields
Zhefu Yu, Paul Martini, T. M. Davis +72
Measurements of the physical properties of accretion disks in active galactic nuclei are important for better understanding the growth and evolution of supermassive black holes. We…
DES15E2mlf: A Spectroscopically Confirmed Superluminous Supernova that Exploded 3.5 Gyr After the Big Bang
Y. -C. Pan, R. J. Foley, M. Smith +63
We present the Dark Energy Survey (DES) discovery of DES15E2mlf, the most distant superluminous supernova (SLSN) spectroscopically confirmed to date. The light curves and Gemini sp…
Extreme variability quasars from the Sloan Digital Sky Survey and the Dark Energy Survey
Nick Rumbaugh, Yue Shen, Eric Morganson +49
We perform a systematic search for long-term extreme variability quasars (EVQs) in the overlapping Sloan Digital Sky Survey (SDSS) and 3-Year Dark Energy Survey (DES) imaging, whic…
The LMC geometry and outer stellar populations from early DES data
Eduardo Balbinot, B. X. Santiago, L. Girardi +50
The Dark Energy Camera has captured a large set of images as part of Science Verification (SV) for the Dark Energy Survey. The SV footprint covers a lar ge portion of the outer Lar…
