When Streams Curve Away: a Test of Dark Matter from Extragalactic Stellar Stream Populations
Nathaniel Starkman, Jacob Nibauer, Sarah Pearson +2
The nature of dark matter sets the shape of galactic halos: collisionless cold dark matter (CDM) predicts triaxial halos, while scattering in self-interacting dark matter (SIDM) ro…
Stellar streams around dwarf galaxies are observationally rare in the local Universe
Joanna D. Sakowska, David Martíınez-Delgado, Sarah Pearson +6
The frequency and properties of stellar streams around dwarf galaxies remain observationally under-explored. Building a statistically significant sample is challenging because dwar…
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…
A near field guide to Roman's wide-area surveys
Robyn E. Sanderson, Kevin A. McKinnon, Adrien C. R. Thob +7
The Nancy Grace Roman Space Telescope currently plans to survey nearly 6000 square degrees of the sky, mainly in the High-Latitude Wide-Area Survey (HLWAS) and Galactic Plane Surve…
Stellar streams around dwarf galaxies in the Local Universe
Joanna D. Sakowska, David Martínez-Delgado, Sarah Pearson +6
While mergers between massive galaxies and their dwarf satellites are well studied, the properties of dwarf - dwarf satellite mergers are not well constrained. Stellar streams trac…
MUSE observations of dwarf galaxies and a stellar stream in the M83 group
Oliver Müller, Marina Rejkuba, Katja Fahrion +8
Spectroscopy for faint dwarf galaxies outside of our own Local Group is challenging. Here, we present MUSE spectroscopy to study the properties of four known dwarf satellites and o…
