Kavli Affiliate: Salman Habib | First 5 Authors: Kelly R. Moran, Richard Payne, Earl Lawrence, David Higdon, Stephen A. Walsh | Summary: The nonlinear matter power spectrum in cosmology describes how matter density fluctuations vary with scale in the universe, providing critical insights into large-scale structure formation. The matter power spectrum includes both smooth regions […]
Kavli Affiliate: Chihway Chang | First 5 Authors: Benjamin Levine, Javier Sánchez, Chihway Chang, Anja von der Linden, Eboni Collins | Summary: The Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) will survey the southern sky to create the largest galaxy catalog to date, and its statistical power demands an improved understanding […]
Kavli Affiliate: Alexander P. Ji | First 5 Authors: Petra Awad, Ting S. Li, Denis Erkal, Reynier F. Peletier, Kerstin Bunte | Summary: As globular clusters (GCs) orbit the Milky Way, their stars are tidally stripped forming tidal tails that follow the orbit of the clusters around the Galaxy. The morphology of these tails is […]
Kavli Affiliate: Savdeep Sethi | First 5 Authors: Gabriel Weiderpass, Mayur Sharma, Savdeep Sethi, , | Summary: A wide range of non-equilibrium phenomena in nature involve non-reciprocal interactions. To understand the novel behaviors that can emerge in such systems, finding tractable models is essential. With this goal, we introduce a non-reciprocal generalization of the kinetic […]
Kavli Affiliate: Savdeep Sethi | First 5 Authors: Gabriel Weiderpass, Mayur Sharma, Savdeep Sethi, , | Summary: Non-reciprocal interactions are a generic feature of non-equilibrium systems. We define a non-reciprocal generalization of the kinetic Ising model in one spatial dimension. We solve the model exactly using two different approaches for infinite, semi-infinite and finite systems […]
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Kylar Greene, Aurora Ireland, Gordan Krnjaic, Yuhsin Tsai, | Summary: A B-mode polarization signal in the cosmic microwave background is widely regarded as smoking gun evidence for gravitational waves produced during inflation. Here we demonstrate that tensor perturbations from a cosmological phase transition in the post-inflationary universe […]
Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Evgeny P. Kurbatov, Vasily Belokurov, Sergey Koposov, Andrey Kravtsov, Elliot Y. Davies | Summary: The innermost portions of the Milky Way’s stellar halo have avoided scrutiny until recently. The lack of wide-area survey data, made it difficult to reconstruct an uninterrupted view of the density distribution of […]
Kavli Affiliate: Elise Jennings | First 5 Authors: Soronzonbold Otgonbaatar, Elise Jennings, , , | Summary: Modern supercomputers can handle resource-intensive computational and data-driven problems in various industries and academic fields. These supercomputers are primarily made up of traditional classical resources comprising CPUs and GPUs. Integrating quantum processing units with supercomputers offers the potential to […]
Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Elliot Y. Davies, Vasily Belokurov, Andrey Kravtsov, Stephanie Monty, GyuChul Myeong | Summary: The stellar halo of the Milky Way comprises an abundance of chemical signatures from accretion events and textit{in-situ} evolution, that form an interweaving tapestry in kinematic space. To untangle this, we consider the mixtures […]
Kavli Affiliate: Brian D. Nord | First 5 Authors: Shrihan Agarwal, Aleksandra Ćiprijanović, Brian D. Nord, , | Summary: Modeling strong gravitational lenses is computationally expensive for the complex data from modern and next-generation cosmic surveys. Deep learning has emerged as a promising approach for finding lenses and predicting lensing parameters, such as the Einstein […]
