A Probabilistic Interpretation of the Ball Mapper Graph
John Rick Manzanares, Jay-Anne Bulauan
We introduce Probabilistic Ball Mapper, a formulation of Ball Mapper in which each data point is assigned a probability distribution supported only on the metric balls that contain…
Constraints on dynamically-formed massive black holes in Little Red Dots from X-ray non-detections
M. Liempi, D. R. G. Schleicher, M. A. Latif +4
The existence of massive, compact galaxies (Little Red Dots, LRDs) at challenges early structure formation models, suggesting rapid stellar and black hole (BH) assembly.…
Massive black hole formation in Population III star clusters
B. Reinoso, M. A. Latif, D. R. G. Schleicher
The James Webb Space Telescope (JWST) has revealed a population of active galactic nuclei (AGNs) that challenge existing black hole (BH) formation models. These newly observed BHs…
Massive black holes or stars first: the key is the residual cosmic electron fraction
Muhammad A. Latif, Sadegh Khochfar
Recent James Webb Space Telescope observations have unveiled that the first supermassive black holes (SMBHs) were in place at z 10, a few hundred Myrs after the Big Bang. Th…
