Kavli Affiliate: Eric D. Miller | First 5 Authors: Gerrit Schellenberger, Ralph Kraft, Paul Nulsen, Eric D. Miller, Marshall W. Bautz | Summary: The level and uncertainty of the particle induced background in CCD detectors plays a crucial role for future X-ray instruments, such as the Wide Field Imager (WFI) onboard Athena. To mitigate the […]

Kavli Affiliate: Lina Necib | First 5 Authors: Tri Nguyen, Justin Read, Lina Necib, Siddharth Mishra-Sharma, Claude-André Faucher-Giguère | Summary: The Dark Matter (DM) distribution in dwarf galaxies provides crucial insights into both structure formation and the particle nature of DM. GraphNPE (Graph Neural Posterior Estimator), first introduced in Nguyen et al. (2023), is a […]

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Oliver Zier, Rahul Kannan, Aaron Smith, Ewald Puchwein, Mark Vogelsberger | Summary: Population III (Pop III) stars are the first stars in the Universe, forming from pristine, metal-free gas and marking the end of the cosmic dark ages. Their formation rate is expected to sharply decline after […]

Kavli Affiliate: Max Tegmark | First 5 Authors: David D. Baek, Max Tegmark, , , | Summary: In this paper, we investigate how model distillation impacts the development of reasoning features in large language models (LLMs). To explore this, we train a crosscoder on Qwen-series models and their fine-tuned variants. Our results suggest that the […]

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Oliver Zier, Oliver Zier, , , | Summary: We investigate the impact of ionizing external ultraviolet (UV) radiation on low-mass haloes ($M_h<10^10M_odot$) at high redshift using $1140M_odot$ baryonic resolution zoom-in simulations of seven regions from the THESAN-ZOOM project. We compare three simulation sets that differ in the […]

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: William McClymont, Sandro Tacchella, Aaron Smith, Rahul Kannan, Ewald Puchwein | Summary: Characterizing the evolution of the star-forming main sequence (SFMS) at high redshift is crucial to contextualize the observed extreme properties of galaxies in the early Universe. We present an analysis of the SFMS and its […]

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Rahul Kannan, Ewald Puchwein, Aaron Smith, Josh Borrow, Enrico Garaldi | Summary: We introduce the THESAN-ZOOM project, a comprehensive suite of high-resolution zoom-in simulations of $14$ high-redshift ($z>3$) galaxies selected from the THESAN simulation volume. This sample encompasses a diverse range of halo masses, with $M_mathrm{halo} approx […]

Kavli Affiliate: Anna Frebel | First 5 Authors: Kaley Brauer, Jennifer Mead, John H. Wise, Greg L. Bryan, Mordecai-Mark Mac Low | Summary: We explore the effect of variations in the Population III (Pop III) initial mass function (IMF) and star-by-star feedback on early galaxy formation and evolution using the Aeos simulations. We compare simulations […]
