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…
JWST Observations of the Double Nucleus in NGC 4486B: Possible Evidence for a Recent Binary SMBH Merger and Recoil
Behzad Tahmasebzadeh, Monica Valluri, Shashank Dattathri +19
A recent study of the compact elliptical galaxy NGC 4486B using JWST-NIRSpec IFU kinematics confirmed a supermassive black hole (SMBH) of mass (~8% of…
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…
Intermediate Mass Black Hole Binary Evolution in Nuclear Star Clusters: the effect of the stellar mass black hole population
Fazeel Mahmood Khan, Peter Berczik, Margarita Sobolenko +4
In this study, we investigate the dynamics of Intermediate-Mass Black Hole (IMBH) binaries within Nuclear Star Clusters (NSCs) that contain a population of stellar-mass black holes…
