Galactic Bar Resonances Inferred from Kinematically Hot Stars in Gaia EDR3
Daisuke Kawata, Junichi Baba, Jason A. S. Hunt +5
Using a numerical simulation of an isolated barred disc galaxy, we first demonstrate that the resonances of the inner bar structure induce more prominent features in the action spa…
The power of co-ordinate transformations in dynamical interpretations of Galactic structure
Jason A. S. Hunt, Kathryn V. Johnston, Alex R. Pettitt +3
DR2 has provided an unprecedented wealth of information about the positions and motions of stars in our Galaxy, and has highlighted the degree of disequilibria in the disc.…
Unveiling the Distinct Formation Pathways of the Inner and Outer Discs of the Milky Way with Bayesian Machine Learning
Ioana Ciucă, Daisuke Kawata, Andrea Miglio +2
We develop a Bayesian Machine Learning framework called BINGO (Bayesian INference for Galactic archaeOlogy) centred around a Bayesian neural network. After being trained on the APO…
Constraining stellar population parameters from narrow band photometric surveys using convolutional neural networks
Choong Ling Liew-Cain, Daisuke Kawata, Patricia Sanchez-Blazquez +2
Upcoming large-area narrow band photometric surveys, such as J-PAS, will enable us to observe a large number of galaxies simultaneously and efficiently. However, it will be challen…
Sausage & Mash: The dual origin of the Galactic thick disc and halo from the gas-rich Gaia-Enceladus-Sausage merger
Robert J. J. Grand, Daisuke Kawata, Vasily Belokurov +6
We analyse a set of cosmological magneto-hydrodynamic simulations of the formation of Milky Way-mass galaxies identified to have a prominent radially anisotropic stellar halo compo…
Explaining the chemical trajectories of accreted and in-situ halo stars of the Milky Way
Chris B. Brook, Daisuke Kawata, Brad K. Gibson +2
The Milky Way underwent its last significant merger ten billion years ago, when the Gaia-Enceladus-Sausage (GES) was accreted. Accreted GES stars and progenitor stars born prior to…
