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 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…
How Fast Could Supermassive Black Holes Grow At the Epoch of Reionization?
Ziyong Wu, Renyue Cen, Romain Teyssier
Utilizing cosmological hydrodynamic simulations we show that there is a brief super-Eddington accretion phase in typical halos at high redshift, impervious to AGN self-regulation.…
Numerical Cosmology
Romain Teyssier
In these lecture notes, we describe the current state-of-the-art for numerical simulations of large-scale structure and galaxy formation. Numerical simulations play a central role…
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…
Cosmological simulations of the same spiral galaxy: satellite properties, the role of baryonic physics and star formation history in shaping dark matter cores/cusps
A. Nuñez-Castiñeyra, E. Nezri, P. Mollitor +3
We investigate the role of baryonic physics in shaping the population, structure, and internal dynamics of galactic subhalos using the Mochima suite of cosmological zoom-in simulat…
Line Intensity Mapping Prediction from the Cosmic Dawn (CoDa) III Simulation for H from Galaxies and the Intergalactic Medium during the Epoch of Reionization
Eugene Hyeonmin Lee, Joohyun Lee, Paul R. Shapiro +13
The evolution of large-scale structure, galaxies and the intergalactic medium (IGM) during the Epoch of Reionization (EoR) can be probed by upcoming Line Intensity Mapping (LIM) ex…
Synergising semi-analytical models and hydrodynamical simulations to interpret JWST data from the first billion years
Valentin Mauerhofer, Pratika Dayal, Martin G. Haehnelt +3
The field of high redshift galaxy formation has been revolutionised by JWST, which is yielding unprecedented insights on galaxy assembly at early times. Our key aim is to study the…
Constructing Merger Trees of Density Peaks Using Phase-Space Watershed Segmentation Algorithm
Robel Geda, Romain Teyssier
Structure identification in cosmological simulations plays an important role in analysing simulation outputs. The definition of these structures directly impacts the inferred prope…
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…
