Forecasting Dark Matter Subhalo Constraints from Stellar Streams using Implicit Likelihood Inference
Tri Nguyen, Rutong Pei, Zhuofu Li +9
The evidence for dark matter (DM) remains compelling, although attempts to understand its particle nature remain inconclusive. One promising method to study DM is detecting DM subh…
: 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…
A second-generation star in a relic dwarf galaxy
Anirudh Chiti, Vinicius M. Placco, Andrew B. Pace +22
Stars that contain only trace amounts of elements heavier than helium, referred to as having low "metallicity", preserve the chemical fingerprints of the first generation of stars…
The DECam Field of Streams: a deep view of the Milky Way halo
Peter Ferguson, Nora Shipp
We present a Field of Streams visualizing stellar structures in the Milky Way halo as viewed by the Dark Energy Camera (DECam). We use - and -band imaging from the Dark Energ…
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…
The DECam MAGIC Survey: A Wide-field Photometric Metallicity Study of the Sculptor Dwarf Spheroidal Galaxy
Fabrícia O. Barbosa, Anirudh Chiti, Guilherme Limberg +26
The metallicity distribution function and internal chemical variations of a galaxy are fundamental to understand its formation and assembly history. In this work, we analyze photom…
