Characterisation of local halo building blocks: Thamnos and Sequoia
Emma Dodd, Tomás Ruiz-Lara, Amina Helmi +5
A crucial aspect of galaxy evolution is the pace at which galaxies build up their mass. We investigate this hierarchical assembly by uncovering and timing accretion events experien…
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…
Filling in the Blanks: A Method to Infer the Substructure Membership and Dynamics of 5D Stars
Thomas M. Callingham, Amina Helmi
We present and test a method to infer a probability density function (PDF) for the missing vlos of a star with 5D information within kpc. We use stars from the Gaia DR3 RVS c…
The 33 M black hole Gaia BH3 is part of the disrupted ED-2 star cluster
E. Balbinot, E. Dodd, T. Matsuno +19
The Gaia Collaboration has recently reported the detection of a 33 M black hole in a wide binary system located in the Solar neighbourhood. Here we explore the relationship…
