Kavli Affiliate: Ran Wang | First 5 Authors: Mohamed Naveed Gul Mohamed, Raman Goyal, Suman Chakravorty, Ran Wang, | Summary: This paper considers the problem of system identification for linear time varying systems. We propose a new system realization approach that uses an "information-state" as the state vector, where the "information-state" is composed of a […]
Kavli Affiliate: E. P. S. Shellard | First 5 Authors: Amelia Drew, E. P. S. Shellard, , , | Summary: We implement adaptive mesh refinement (AMR) simulations of global topological strings using the public code, GRChombo. We perform a quantitative investigation of massive radiation from single sinusoidally displaced string configurations, studying a range of string […]
Kavli Affiliate: Clarence L. Chang | First 5 Authors: Aaron S. Chou, Marcelle Soares-Santos, Tim M. P. Tait, Rana X. Adhikari, Luis A. Anchordoqui | Summary: This report summarizes the current status of Cosmic Frontier physics and the broad and exciting future prospects identified for the Cosmic Frontier as part of the 2021 Snowmass Process. […]
Kavli Affiliate: Eric D. Miller | First 5 Authors: Ralph Kraft, Maxim Markevitch, Caroline Kilbourne, Joseph S. Adams, Hiroki Akamatsu | Summary: The Line Emission Mapper (LEM) is an X-ray Probe for the 2030s that will answer the outstanding questions of the Universe’s structure formation. It will also provide transformative new observing capabilities for every […]
Kavli Affiliate: Debora Sijacki | First 5 Authors: Sergio Martin-Alvarez, Debora Sijacki, Martin G. Haehnelt, Marion Farcy, Yohan Dubois | Summary: Enshrouded in several well-known controversies, dwarf galaxies have been extensively studied to learn about the underlying cosmology, notwithstanding that physical processes regulating their properties are poorly understood. To shed light on these processes, we […]
Kavli Affiliate: Jia Liu | First 5 Authors: Xiao-Qing Liu, Jia Liu, Zheng-Yuan Xue, , | Summary: Quantum computation attaches importance to high-precision quantum manipulation, where the quantum state transfer with high fidelity is necessary. Here, we propose a new scheme to implement the quantum state transfer of high fidelity and long distance, by adding […]
Kavli Affiliate: Philip J. Marshall | First 5 Authors: Ji Won Park, Simon Birrer, Madison Ueland, Miles Cranmer, Adriano Agnello | Summary: We present a Bayesian graph neural network (BGNN) that can estimate the weak lensing convergence ($kappa$) from photometric measurements of galaxies along a given line of sight. The method is of particular interest […]
Kavli Affiliate: Aaron Roodman | First 5 Authors: Ji Won Park, Simon Birrer, Madison Ueland, Miles Cranmer, Adriano Agnello | Summary: We present a Bayesian graph neural network (BGNN) that can estimate the weak lensing convergence ($kappa$) from photometric measurements of galaxies along a given line of sight. The method is of particular interest in […]
Kavli Affiliate: Jing Wang | First 5 Authors: Phanuel Mariano, Jing Wang, , , | Summary: Assuming the heat kernel on a doubling Dirichlet metric measure space has a generalized sub-Gaussian bound, we prove an asymptotically sharp spectral upper bound on the survival probability of the associated diffusion process. As a consequence, we can show […]
Kavli Affiliate: Joshua A. Frieman | First 5 Authors: Jason Poh, Ashwin Samudre, Aleksandra Ćiprijanović, Brian Nord, Gourav Khullar | Summary: Current ground-based cosmological surveys, such as the Dark Energy Survey (DES), are predicted to discover thousands of galaxy-scale strong lenses, while future surveys, such as the Vera Rubin Observatory Legacy Survey of Space and […]
