Towards a universal analytical model for Population III star formation: interplay between feedback and fragmentation
ABSTRACT JWST has brought us new insights into Cosmic Dawn with tentative detection of
the unique signatures of metal-free Population III (Pop III) stars, such as strong He II …

High-redshift JWST massive galaxies and the initial clustering of supermassive primordial black holes
HL Huang, JQ Jiang, YS Piao - Physical Review D, 2024 - APS
In this paper, we show that the initial clustering of supermassive primordial black holes
(SMPBHs) beyond a Poisson distribution can efficiently enhance the matter power spectrum …

Signatures of black hole seeding in the local Universe: Predictions from the BRAHMA cosmological simulations
The first" seeds" of supermassive black holes (BHs) continue to be an outstanding puzzle,
and it is currently unclear whether the imprints of early seed formation survive today. Here …
