Hidden Disruption in Milky Way-like Satellite Galaxy Populations
Gray Thoron, Nora Shipp, Alexander H. Riley +9
Determining whether a satellite galaxy is tidally disrupting from photometric observations alone remains a fundamental challenge in near-field cosmology. Cosmological simulations o…
The Carbon-Dependent Binary Frequency of CEMP-no Stars
John D. Dixon, Terese T. Hansen, Jennifer Marshall +15
Studies of the oldest and most metal-poor stars in the Milky Way confirm a common chemical signature of high carbon abundances and subsolar neutron-capture enrichment. The so-calle…
The DECam MAGIC Survey Mapping the Ancient Galaxy in CaHK: Overview and Summary of Early Science
A. Chiti, A. Drlica-Wagner, A. B. Pace +42
We present the DECam Mapping the Ancient Galaxy in CaHK (MAGIC) survey, a 54-night NOIRLab Survey Program to image 5,000deg of the southern hemisphere using a meta…
No Stream Left Unscathed: The imprint of a host galaxy
Arpit Arora, Peter S. Ferguson, Jacob Nibauer +11
Stellar streams from disrupted globular clusters are excellent probes of dark matter (DM) subhalos. Observed Milky Way streams display a remarkable diversity of features: spurs, ga…
The DECam MAGIC Survey: Investigating the Jet Stellar Stream with Photometric Metallicities
H. Q. Do, A. Chiti, P. S. Ferguson +27
Stellar streams are dynamically fragile structures formed by the tidal disruption of dwarf galaxies and stellar clusters. These objects are valuable tracers of the gravitational po…
TOI-7169 b: A Hot Jupiter Transiting a Metal-Poor Star
Joshua D. Simon, Joseph E. Rodriguez, Jhon Yana Galarza +38
Most known planets are found around metal-rich host stars, which has made it difficult to determine whether a lower metallicity limit for planet formation exists and how the proper…
A Path to an All-Sky Survey with Roman
Jiwon Jesse Han, Anirudh Chiti, Kai-Feng Chen +93
A deep, space-based, all-sky near-infrared survey carried out with the Nancy Grace Roman Space Telescope would constitute a foundational astronomical infrastructure for decades to…
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…
