Transformational astrophysics and exoplanet science with Habitable Worlds Observatory's High Resolution Imager
Vincent Van Eylen, Richard Massey, Saeeda Awan +167
Habitable Worlds Observatory (HWO) will be NASA's flagship space telescope of the 2040s, designed to search for life on other planets and to transform broad areas of astrophysics.…
Orbital migration and heating history of the Galactic disc: a transition between the bimodal discs
HanYuan Zhang, Vasily Belokurov, Jason L. Sanders +7
Stellar orbits in the Galactic disc evolve from their birth to the current shape through both radial migration and dynamical heating. The history of their secular evolution is impr…
Thick-to-thin disc transition and gas disc shrinking induced by the Gaia-Sausage-Enceladus merger
Natsuki Funakoshi, Daisuke Kawata, Jason L. Sanders +3
Understanding the Milky Way disc formation requires characterising its structural and kinematic properties as functions of stellar age. Using red giant stars from APOGEE DR17 and G…
GalactiKit: reconstructing mergers from debris using simulation-based inference in Auriga
Andrea Sante, Daisuke Kawata, Andreea S. Font +1
We present GalactiKit, a data-driven methodology for estimating the lookback infall time, stellar mass, halo mass and mass ratio of the disrupted progenitors of Milky Way-like gala…
