Kavli Affiliate: Blake Sherwin | First 5 Authors: Karen Perez Sarmiento, Alex Laguë, Mathew Madhavacheril, Bhuvnesh Jain, Blake Sherwin | Summary: We reconstruct the non-linear matter power spectrum $P(k)$ using a joint analysis of gravitational lensing of the cosmic microwave background (CMB) and lensing of galaxies. This reconstruction is motivated by the $S_8$ tension between […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Dávid Puskás, Sandro Tacchella, Charlotte Simmonds, Kevin Hainline, Francesco D’Eugenio | Summary: We present a comprehensive analysis of galaxy close-pair fractions and major merger rates to evaluate the importance of mergers in the hierarchical growth of galaxies over cosmic time. This study focuses on the previously poorly […]
Kavli Affiliate: George Efstathiou | First 5 Authors: Simon Pochinda, Jiten Dhandha, Anastasia Fialkov, Eloy de Lera Acedo, | Summary: In this study, we train score-based diffusion models to super-resolve gigaparsec-scale cosmological simulations of the 21-cm signal. We examine the impact of network and training dataset size on model performance, demonstrating that a single simulation […]
Kavli Affiliate: Martin Haehnelt | First 5 Authors: Marion Farcy, Joakim Rosdahl, Yohan Dubois, Jérémy Blaizot, Sergio Martin-Alvarez | Summary: 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 its impact on the escape of […]

Kavli Affiliate: Debora Sijacki | First 5 Authors: Leah Bigwood, Martin A. Bourne, Vid Irsic, Alexandra Amon, Debora Sijacki | Summary: While cosmological simulations of galaxy formation have reached maturity, able to reproduce many fundamental galaxy and halo properties, no consensus has yet been reached on the impact of `baryonic feedback’ on the non-linear matter […]
Kavli Affiliate: Debora Sijacki | First 5 Authors: Xihan Ji, Roberto Maiolino, Hannah Übler, Jan Scholtz, Francesco D’Eugenio | Summary: Recent observations from JWST have revealed an abundant population of active galactic nuclei (AGN) and so-called “Little Red Dots” (LRDs) at $2lesssim z lesssim 11$, many of which are characterized by V-shaped UV-to-optical continua with […]

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Qinyue Fei, John D. Sivlerman, Seiji Fujimoto, Ran Wang, Luis C. Ho | Summary: We conduct a study of the gas kinematics of two quasar host galaxies at $zgtrsim6$ traced by the [CII] emission line using ALMA. By combining deep observations at both low and high resolution, […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: William M. Baker, Francesco D’Eugenio, Roberto Maiolino, Andrew J. Bunker, Charlotte Simmonds | Summary: We use NIRSpec MSA spectroscopy and NIRCam Photometry to explore the properties of JADES-GS8-RL-1, a rapidly quenched, $z=8.5$ galaxy with a stellar mass of $10^{8.9}M_odot$, a steep blue UV slope, a Balmer break, […]
