Extragalactic Stellar Streams in Time-Dependent Cosmological Halos
Sarah Pearson, Jacob Nibauer, Emily C. Cunningham +4
Upcoming and ongoing surveys will detect thousands of stellar streams around galaxies other than the Milky Way. Studies from the Milky Way have shown that time-dependent evolution…
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…
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…
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…
