The NIVARIA-Local Group simulations: Unveiling the origin of rotation curve diversity in dwarf galaxies and its connection to galaxy morphology

A. Contreras-Santos, A. Di Cintio, A. Negri +7

Dwarf galaxies exhibit a large diversity in rotation curve shapes, challenging galaxy formation models within the CDM paradigm. We present NIVARIA-LG, a new suite of cosmologica…

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…

Formation of a nuclear star cluster through the inspiral of globular clusters: A case study of the dwarf elliptical galaxy UGC 7346

Ismael Khan, Fazeel Mahmood Khan, Andrea V. Macciò +2

Nuclear star clusters (NSCs) are dense stellar environments located in the center of most galaxies. NSCs are thought to form through two primary methods; through the inspiral of gl…

Feedback driven interactions between dark and luminous matter to explain tight galaxy scaling relations

Leen Alrawas, Andrea V. Macciò, Carlo Cannarozzo

The tight empirical correlation linking the stellar disk scale length to the dark matter scale radius has been proposed as possible evidence for a fundamental coupling…

Causal Reversal in the $M_\unicode{x25CF}\unicode{x2013}σ_0$ 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…
