The Age-Thickness Relation of the Milky Way Disk: A Tracer of Galactic Merging History
Lekshmi Thulasidharan, Elena D'Onghia, Robert Benjamin +3
The prevailing model of galaxy formation proposes that galaxies like the Milky Way are built through a series of mergers with smaller galaxies over time. However, the exact details…
Constraints on the history of Galactic spiral arms revealed by Gaia GSP-Spec alpha-elements
M. Barbillon, A. Recio-Blanco, E. Poggio +4
The distribution of chemical elements in the Galactic disc can reveal fundamental clues on the physical processes that led to the current configuration of our Galaxy. We map chemic…
Comment on 'a slightly oblate dark matter halo revealed by a retrograde precessing Galactic disk warp' by Huang et al
Walter Dehnen, Ralph Schönrich, Ronald Drimmel +3
Huang et al. (2024) measured the derivative of the phase of the Galactic warp traced by classical Cepheids with respect to their age and interpreted it as th…
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…
