The Age-Thickness Relation as a Tracer of the Merger History of Disk Galaxies
Lekshmi Thulasidharan, Elena D'Onghia, Robert Benjamin +2
In the hierarchical framework of galaxy formation, disk galaxies are shaped by a sequence of mergers and interactions, yet reconstructing this history from observations remains cha…
Azimuthal Misalignments in Stellar Warp Structure as Dynamical Tracers of Mergers in Milky Way-like Galaxies
Lekshmi Thulasidharan, Elena D'Onghia, Robert Benjamin
We investigate the origin of warps in stellar disks using high-resolution Milky Way analogs from the IllustrisTNG50 simulation. Focusing on galaxies that experienced a major merger…
The Great Wave: Evidence of a large-scale vertical corrugation propagating outwards in the Galactic disc
E. Poggio, S. Khanna, R. Drimmel +6
We analyse the three-dimensional structure and kinematics of two samples of young stars in the Galactic disc, containing respectively young giants (17000 stars out to he…
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…
