Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Wenzer Qin, Katelin Schutz, Olivia Rosenstein, Stephanie O’Neil, Mark Vogelsberger | Summary: We show that perturbative techniques inspired by effective field theory (EFT) can be used to "paint on" the 21~cm field during reionization using only the underlying linear density field. This procedure is accurate to within […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Vinh Tran, Vinh Tran, , , | Summary: Core collapse, a process associated with self-interacting dark matter (SIDM) models, can increase the central density of halos by orders of magnitude with observable consequences for dwarf galaxy properties and gravitational lensing. Resonances in the self-interaction cross section, features […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Xinghong Fu, Ziming Liu, Max Tegmark, , | Summary: When two AI models are trained on the same scientific task, do they learn the same theory or two different theories? Throughout history of science, we have witnessed the rise and fall of theories driven by experimental validation […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Emily K Pass, David Charbonneau, Andrew Vanderburg, , | Summary: Detecting and characterizing the atmospheres of terrestrial exoplanets is a key goal of exoplanetary astronomy, one that may now be within reach given the upcoming campaign to conduct a large-scale survey of rocky M-dwarf worlds with the […]

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Filippo Barbani, Raffaele Pascale, Federico Marinacci, Paul Torrey, Laura V. Sales | Summary: Galaxies are not isolated systems; they continuously interact with their surroundings by ejecting gas via stellar feedback and accreting gas from the environment. Understanding the interplay between outflows from the disc and the surrounding […]
Kavli Affiliate: Catherine E. Grant | First 5 Authors: Arnab Sarkar, Michael McDonald, Lindsey Bleem, Mark Bautz, Bradford A. Benson | Summary: We present joint South Pole Telescope (SPT) and XMM-Newton observations of 8 massive galaxy clusters (0.8–1.7$times$10$^{15}$ M$_{odot}$) spanning a redshift range of 0.16 to 0.35. Employing a novel SZ+X-ray fitting technique, we effectively […]

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Fangzhou Jiang, Zixiang Jia, Haonan Zheng, Luis C. Ho, Kohei Inayoshi | Summary: We present a statistical study on the formation and growth of black holes (BHs) seeded by gravothermal core-collapse of self-interacting dark matter (SIDM) halos at high redshifts, using a semi-analytical framework based on Monte-Carlo […]
