Supermassive Black Hole Growth in Massive Galaxies at Cosmic Dawn

James Sunseri, Zachary L. Andalman, Romain Teyssier

Among the emerging excess of massive, bright galaxies at Cosmic Dawn seen by the James Webb Space Telescope, several exhibit spectral features associated with active…

The AGORA High-resolution Galaxy Simulations Comparison Project. XI: Solving the Non-Spherical Morphology and Evolution of Dark Matter Halos with Haskap Pie

Kirk S. S. Barrow, Thinh Huu Nguyen, Santi Roca-FÃ brega +26

We introduce a halo solving and tracking procedure that intrinsically treats dark matter halos as non-spherical objects by leveraging the bound particle searching techniques used i…

Redshift Evolution of the Ratio of Supermassive Black Hole Mass to Stellar Mass

Ziyong Wu, Renyue Cen, Romain Teyssier

We run and analyze a suite of high-redshift zoom-in cosmological simulations with varying supernova feedback and supermassive black hole (SMBH) accretion prescriptions to study the…

The AGORA High-resolution Galaxy Simulations Comparison Project. X: Formation and Evolution of Galaxies at the High-redshift Frontier

Hyeonyong Kim, Ji-hoon Kim, Minyong Jung +22

Recent observations from JWST have revealed unexpectedly luminous galaxies, exhibiting stellar masses and luminosities significantly higher than predicted by theoretical models at…

From Feedback-Free Star Clusters to Little Red Dots via Compaction

Avishai Dekel, Dhruba Dutta Chowdhury, Sharon Lapiner +6

We address the origin of the Little Red Dots (LRDs) seen by JWST at cosmic morning () as compact stellar systems with over-massive black holes (BHs). We propose…

The impact of cosmic ray feedback during the epoch of reionisation

Marion Farcy, Joakim Rosdahl, Yohan Dubois +5

Galaxies form and evolve via a multitude of complex physics. In this work, we investigate the role of cosmic ray (CR) feedback in galaxy evolution and reionisation, by examining it…
