Causes of Hot Jupiter Inflation from Causal Discovery
Zehao Jin, Mohamad Ali-Dib, Yujia Zheng +3
Hot Jupiters often have radii larger than predicted by standard cooling--contraction models, but it remains unclear which process supplies or preserves the extra internal heat. We…
Causal Reversal in the $M_\unicode{x25CF}\unicode{x2013}Ï_0$ Relation: Implications for High-Redshift Supermassive Black Hole Mass Estimates
Benjamin L. Davis, Saakshi More, Zehao Jin +3
The nascent methodology of applying the principles of causal discovery to astrophysical data has produced affirming results about deeply held theories concerning the causal nature…
Two faces of Gaia-Sausage-Enceladus: Mining the chemical abundance space with graph attention networks
Milan Quandt-Rodriguez, Sara Lucatello, Lorenzo Spina +2
Recent studies suggest that chemical abundances hold the key to disentangling halo substructure, providing a more reliable tracer than dynamics alone. We aim to probe the Milky Way…
GW emission and relativistic dynamical friction in intermediate mass ratio inspirals
P. Di Cintio, G. Bertone, C. Chiari +4
We present a set of preliminary simulations of intermediate mass ratio inspirals (IMRIs) inside dark matter (DM) spikes accounting for post-Newtonian corrections the interaction be…
Chaos in violent relaxation dynamics. Disentangling micro- and macro-chaos in numerical experiments of dissipationless collapse
Simone Sartorello, Pierfrancesco Di Cintio, Alessandro Alberto Trani +1
Violent relaxation (VR) is often regarded as the mechanism leading stellar systems to collisionless meta equilibrium via rapid changes in the collective potential. We investigate t…
Causal Discovery in Astrophysics: Unraveling Supermassive Black Hole and Galaxy Coevolution
Zehao Jin, Mario Pasquato, Benjamin L. Davis +9
Correlation does not imply causation, but patterns of statistical association between variables can be exploited to infer a causal structure (even with purely observational data) w…
