Evidence for the First Globular Cluster Stellar Stream beyond the Milky Way

Julie Kiel Holm, Sarah Pearson, Jacob Nibauer +5

The dark matter content of ultra-diffuse galaxies is the subject of considerable debate. Stellar streams, which form when a host galaxy tidally strips stars from an orbiting stella…

Euclid Quick Data Release (Q1): The geometry of dark matter halos from extragalactic streams

Euclid Collaboration, N. Starkman, J. Nibauer +295

Wide-field surveys like Euclid mark a new era of extragalactic stellar stream studies. With a large number of streams, it is now possible to constrain the dark matter halos of gala…

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…

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…

Potamides: Mapping Dark Matter Halo Shapes from Stellar Stream Tracks in the Local Universe

Sirui Wu, Nathaniel Starkman, Sarah Pearson +3

Stellar streams trace the gravitational potential of their host galaxies and offer a direct probe of dark matter halo geometry. Cosmological simulations predict that halo shapes de…

Testing Dark Matter with Generative Models for Extragalactic Stellar Streams

Jacob Nibauer, Sarah Pearson

Upcoming ground and space-based surveys are poised to illuminate low surface brightness tidal features, providing a new observable connection to dark matter physics. From imaging o…
