Which Milky Way Streams Make the Best Dark Matter Detectors?

Vedant Chandra, Charlie Conroy, Risa Wechsler +7

The abundance and properties of low-mass dark matter subhalos can be inferred by measuring the density and velocity structure of stellar streams, testing physical models of dark ma…

Detectable subhalo impacts in Milky Way streams

Junyang Lu, Elias Bernreuther, Tongyan Lin +3

Dark matter subhalos leave gravitational imprints in the stellar streams of the Milky Way. Observing individual strong impacts of subhalos offers a compelling way to constrain and…

The Binary Populations of Stellar Streams are Set by Cluster Dynamics

Anya Phillips, Charlie Conroy, Jacob Nibauer +5

We present a suite of direct N-body simulations of low mass () globular cluster streams initialized with observationally-motivated binary demographics in order to…

That's so Retro: The Gaia-Sausage-Enceladus Merger Trajectory as the Origin of the Chemical Abundance Bimodality in the Milky Way Disk

James W. Johnson, Diane K. Feuillet, Ana Bonaca +1

The Milky Way (MW) is thought to have experienced a 3:1 mass-ratio merger event near redshift with a significantly retrograde trajectory. This now-disrupted dwarf ga…

Measurement of Substructure from the Kinematics of the GD-1 Stellar Stream

Jacob Nibauer, Ana Bonaca, Adrian M. Price-Whelan +2

Stellar streams are sensitive tracers of low-mass dark matter subhalos and provide a means to test the Cold Dark Matter (CDM) paradigm on small scales. In this work, we connect the…

Breaking Down the : Toward Modeling and Understanding Globular Cluster Stellar Streams in a Fully Cosmological Context

Nondh Panithanpaisal, Robyn E. Sanderson, Carl L. Rodriguez +7

Next-generation surveys are expected to uncover thousands of globular cluster (GC) stellar streams, motivating the need for a theoretical framework that produces realistic GC strea…
