The low-mass and structured stellar halo of M83 argues against a merger origin for its starburst and extended neutral hydrogen disk
Eric F. Bell, Benjamin Harmsen, Matthew Cosby +12
A merger origin has been suggested for M83's massive, metal-rich extended HI disk and nuclear starburst. We observe M83's stellar halo to test this idea. We train nearest-neighbor…
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…
STRRINGS: STReams in Residual Images of Nearby GalaxieS
E. Sola, D. Chemaly, V. Belokurov +11
Tidal features from galaxy mergers, particularly stellar streams, offer valuable insights into galaxy assembly and dark matter halo properties. This paper aims to identify a large…
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…
Galactic Accelerations from the GD-1 Stream Suggest a Tilted Dark Matter Halo
Jacob Nibauer, Ana Bonaca
Cold dark matter halos are expected to be triaxial and often tilted relative to the stellar disk. Stellar streams provide a sensitive tracer of the Milky Way's halo shape, though m…
