Learning the Universe at High Redshifts: Impact of Accretion Modeling on Early Black Hole Growth
Jonathan Kho, Aklant K. Bhowmick, Rainer Weinberger +8
JWST discoveries of the earliest () supermassive black holes (BHs, ) challenge the BH seeding and accretion models of most cosmol…
Learning the Universe with PRFM-vol: Introducing a new subgrid model for star formation in cosmological simulations
Jan D. Burger, Volker Springel, Eve C. Ostriker +7
We introduce PRFM-vol, a new subgrid model for star formation in cosmological simulations that aims to increase the physical realism of cosmological simulations by leveraging resul…
Blue Monsters and Dusty Descendants: Reconciling UV and IR Emission from Galaxies from z=7, up to z= 14
Laura Sommovigo, Lachlan Lancaster, Shyam H. Menon +3
Recent JWST observations reveal massive, UV-bright galaxies at with little apparent dust attenuation, whereas ALMA detections at show similarly massive system…
Chemical Signatures of Population III Stars in Damped Lyman- Absorption Systems at
Eli Visbal, Greg L. Bryan, Zoltan Haiman
Recently, Sodini et al. (2024) presented a sample of OI damped Lyman- absorption system (DLA) analogs at that contain possible chemical signatures of Population III (P…
LAP1-B is the First Observed System Consistent with Theoretical Predictions for Population III Stars
Eli Visbal, Ryan Hazlett, Greg L. Bryan
Recently, Nakajima et al. (2025) presented James Webb Space Telescope observations of the Population III (Pop III) candidate LAP1-B, which is gravitationally lensed by gala…
Modeling Cosmic Rays at AGN Jet-Driven Shock Fronts
Kung-Yi Su, Greg L. Bryan, Philip F. Hopkins +4
Active Galactic Nuclei (AGN) feedback is a key physical mechanism proposed to regulate star formation, primarily in massive galaxies. In particular, cosmic rays associated with AGN…
