Beyond Extreme Burstiness: Evolving Star Formation Efficiency as the Key to Early Galaxy Abundance
Abhijnan Kar, Shadab Alam, Joseph Silk
JWST observations have revealed an overabundance of bright galaxies at , creating apparent tensions with theoretical predictions within standard CDM cosmology. We addr…
Supermassive black hole growth in hierarchically merging nuclear star clusters
Konstantinos Kritos, Ricarda S. Beckmann, Joseph Silk +5
Supermassive black holes are prevalent at the centers of massive galaxies, and their masses scale with galaxy properties, increasing evidence suggesting that these trends continue…
TRINITY VI: Connection between Galaxy Star Formation Rates and Supermassive Black Hole Accretion Rates from z=0-10
Haowen Zhang, Peter Behroozi, Marta Volonteri +6
We infer supermassive black hole (SMBH) accretion rates and Eddington ratios as a function of SMBH/host galaxy mass and redshift with the empirical TRINITY model of dark matter hal…
Which came first: supermassive black holes or galaxies? Insights from JWST
Joseph Silk, Mitchell Begelman, Colin Norman +2
Insights from JWST observations suggest that AGN feedback evolved from a short-lived, high redshift phase in which radiatively cooled turbulence and/or momentum-conserving outflows…
Density profile of dark matter haloes and galaxies in the Horizon-AGN simulation: the impact of AGN feedback
S. Peirani, Y. Dubois, M. Volonteri +7
Using a suite of three large cosmological hydrodynamical simulations, Horizon-AGN, Horizon-noAGN (no AGN feedback) and Horizon-DM (no baryons), we investigate how a typical sub-gri…
