The Milky Way in motion: gauging stellar trajectories that shape the Galactic thin disc
M. L. L. Dantas, R. Smiljanic, R. S. de Souza +2
As stars traverse the Milky Way, their orbits evolve through perturbations that alter their orbital radii. These changes arise from two mechanisms: churning, which modifies angular…
Diving into dangerous tides: The impact of galaxy cluster tidal environments on satellite galaxy mass densities
Matias Blaña, Thomas H. Puzia, Yasna Ordenes-Briceño +8
Satellite galaxies endure powerful environmental tidal forces that drive mass stripping of their outer regions. Consequently, satellites located in central regions of galaxy cluste…
Differences in baryonic and dark matter scaling relations of galaxy clusters: A comparison between IllustrisTNG simulations and observations
Daniel Miller, Diego Pallero, Patricia B. Tissera +1
We compare the self-similar baryonic mass fraction scaling relations between galaxy clusters from the South Pole Telescope Sunyaev-Zel'dovich (SPT-SZ) survey and the IllustrisTNG s…
Probing the origins. II. Unravelling lithium depletion and stellar motion: Intrinsic stellar properties drive depletion, not kinematics
M. L. L. Dantas, R. Smiljanic, D. Romano +4
In Paper I, we classified a stellar sample from the thin disc with a broad range in metallicity as being churned outward or inward, or blurred/undisturbed. In this paper (Paper II)…
Hidden Figures in the Sky: Evolution of low-surface brightness galaxies from a hydro-dynamical perspective
D. Stoppacher, P. Tissera, Y. Rosas-Guevara +2
Low-surface brightness galaxies (LSBGs) are defined as galaxies with central surface brightness levels fainter than the night sky, making them challenging to observe. A key open qu…
Probing the origins. I. Generalised Additive Model inference of birth radii for Milky Way stars in the solar vicinity
M. L. L. Dantas, R. Smiljanic, R. S. de Souza +2
We employ a Generalised Additive Model (GAM) to address the limitations inherent in radial metallicity gradients predicted by chemical evolution models, thereby facilitating the es…
