In a following paper, we apply this method to real 5D data, finding new likely members of known substructures. Thanks to @amina_helmi and the group at the Kapteyn Institute for your comments and support!

We test our methodology on 6D samples and show that our vlos predictions and membership probabilities are statistically accurate. For most groups, high-purity samples CAN be selected from 5D data, with a statistical trade-off between selecting purity and completeness.

We have developed a method to infer the likely line-of-sight velocity (vlos), dynamics, and substructure membership of 5D stars within 2.5kpc of the sun.

We show that Gaia BH3 is part of the ED-2 star cluster. The update astrometry puts GaiaBH3 in excellent agreement with the orbit of ED-2. Using some @ESO data we got last period we also show that ED-2 is very likely a disrupted globular cluster

Interested in Galactic dynamics? But also interested in element abundances? Check out our new paper (ui.adsabs.harvard.edu/abs/2023arXiv2…), where we use a generative model to measure the acceleration field, mass density, and amount of dark matter in the MW disc with element abundances. 🧵

We are growing at the @ICC_UB , remember you can take any of these postdoc fellowships to Barcelona: Marie Curie (EU commission), Juan de la Cierva (Spanish Ministry), Beatriu del Pino (Catalan Government), La Caixa Junior Leader. Plan ahead, get in touch! I will sponsor you.

Very impressed with the science coming out of #iaus379. It's a wonderful time to study galactic dynamics! Massive appreciation to @alexanderpji for relaying every moment of it!

Richard Bower was energetic, brilliant, kind and undoubtedly unique. We're better off for all that he has given us and all the poorer that he's left us so soon. He will be sorely missed.

Galaxy mergers and alien life! Interviewed @Emma_L_Dodd and @astrosoof for the In Science podcast. The future looks bright with new generation researchers like them! #womeninscience

A very clever paper by Callingham et al. on arXiv this morning. Uses the distribution of energy and angular momentum of satellite galaxies in the Eagle cosmological simulations to infer the mass of the Milky Way. arxiv.org/abs/1808.10456
