Testing MOND using the dynamics of nearby stellar streams
Orlin Koop, Amina Helmi
The stellar halo of the Milky Way is built up, at least in part, from debris from past mergers. Stars from such merger events define substructures in phase-space, for example in th…
On the Galactic rotation curve inferred from the Jeans equations Assessing its robustness using Gaia DR3 and cosmological simulations
Orlin Koop, Teresa Antoja, Amina Helmi +2
Several works have recently applied Jeans modelling to Gaia-based datasets to infer the circular velocity curve for the Milky Way. Such works have consistently found evidence for a…
Swarming in stellar streams: Unveiling the structure of the Jhelum stream with ant colony-inspired computation
Petra Awad, Marco Canducci, Eduardo Balbinot +8
The halo of the Milky Way galaxy hosts multiple dynamically coherent substructures known as stellar streams that are remnants of tidally disrupted systems such as globular clusters…
Characterization and dynamics of the peculiar stream Jhelum, A tentative role for the Sagittarius dwarf galaxy
Hanneke C. Woudenberg, Orlin Koop, Eduardo Balbinot +1
Stellar streams are a promising tool to study the Milky Way's dark matter subhalo population, as interactions with subhalos could produce substructure in streams. However, other po…
