The birth of the intracluster medium: the evolution of multiphase gas and Lyman- haloes in a simulated protocluster
Jake S. Bennett, Aaron Smith, Fabrizio Arrigoni-Battaia +3
The paper uses a high‑resolution cosmological zoom‑in simulation of a massive protocluster to study how multiphase gas and Lyman‑α/ H‑α haloes evolve from redshift ~4.4 to 2.7, hig…
Supermassive Black Hole Assembly from Heavy Seeds with Dynamical Friction in the BRAHMA Simulations: Implications for JWST, LISA, and the Local Universe
Aklant K. Bhowmick, Laura Blecha, Paul Torrey +8
The JWST discoveries of supermassive black holes (BHs) at may provide key insights into their seeding origins. Using new BRAHMA cosmological sim…
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…
The evolution of the baryonic content and mass profiles of satellite galaxies in the MTNG simulations
Sergio Contreras, Raul E. Angulo, Giovanni Aricò +5
Empirical models often rely on key relations from the galaxy--halo connection to construct mock galaxy catalogues. These relations typically describe central galaxies more accurate…
Introducing sapphire: Towards Hybrid Physics-Informed, Data-Driven Modeling of Galaxy Formation
Viraj Pandya, Greg L. Bryan, T. Lucas Makinen +18
Semi-analytic models (SAMs) have been treating galaxy populations as dynamical systems for years, but their evolution equations remain poorly constrained. We introduce…
