Signatures of simulated spiral arms on radial actions
P. A. Palicio, A. Recio-Blanco, T. Tepper-Garcia +7
Among the various implications of the spiral arms, it has been observed in the Milky Way disc that the distribution of radial actions from the Gaia Data Release 3 exhibits structur…
Nexus: A framework for conrolled simulations of idealised galaxies
Thor Tepper-Garcia, Joss Bland-Hawthorn, Eugene Vasiliev +3
Motivated by the need for realistic, dynamically self-consistent, evolving galaxy models that avoid the complexity of full, and zoom-in, cosmological simulations, we have developed…
Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry
Gaia Collaboration, P. Panuzzo, T. Mazeh +412
Gravitational waves from black-hole merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected base…
Turbulent gas-rich disks at high redshift: bars & bulges in a radial shear flow
Joss Bland-Hawthorn, Thor Tepper-Garcia, Oscar Agertz +1
Recent observations of high-redshift galaxies () reveal that a substantial fraction have turbulent, gas-rich disks with well-ordered rotation and elevated levels of s…
Galactic-Seismology Substructures and Streams Hunter with LAMOST and Gaia. I. Methodology and Local Halo Results
Guan-Yu Wang, Hai-Feng Wang, Yang-Ping Luo +4
We present a novel, deep-learning based method -- dubbed Galactic-Seismology Substructures and Streams Hunter, or GS Hunter for short, to search for substructures and streams…
