Detecting Solar System Analogs through Joint Radial Velocity/Astrometric Surveys

Kavli Affiliate: David N. Spergel | First 5 Authors: Daniel A. Yahalomi, Ruth Angus, David N. Spergel, Daniel Foreman-Mackey, | Summary: Earth-mass exoplanets on year-long orbits and cool gas giants (CGG) on decade-long orbits lie at the edge of current detection limits. The Terra Hunting Experiment (THE) will take nightly radial velocity (RV) observations on […]

Chiral spin liquid in a $mathbb{Z}_3$ Kitaev model

Kavli Affiliate: Cheng Peng | First 5 Authors: Li-Mei Chen, Tyler D. Ellison, Meng Cheng, Peng Ye, Ji-Yao Chen | Summary: We study a $mathbb{Z}_3$ Kitaev model on the honeycomb lattice with nearest neighbor interactions. Based on matrix product state simulations and symmetry considerations, we find evidence that, with ferromagnetic isotropic couplings, the model realizes […]

Stochastic gravitational wave background from supernovae in massive scalar-tensor gravity

Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Roxana Rosca-Mead, Michalis Agathos, Christopher J. Moore, Ulrich Sperhake, | Summary: In massive scalar-tensor gravity, core-collapse supernovae are strong sources of scalar-polarized gravitational waves. These can be detectable out to large distance. The dispersive nature of the propagation of waves in the massive scalar field mean the […]

Modeling the Galaxy Distribution in Clusters using Halo Cores

Kavli Affiliate: Lindsey Bleem | First 5 Authors: Danila Korytov, Esteban Rangel, Lindsey Bleem, Nicholas Frontiere, Salman Habib | Summary: The galaxy distribution in dark matter-dominated halos is expected to approximately trace the details of the underlying dark matter substructure. In this paper we introduce halo `core-tracking’ as a way to efficiently follow the small-scale […]

Semantic-Guided Generative Image Augmentation Method with Diffusion Models for Image Classification

Kavli Affiliate: Feng Wang | First 5 Authors: Bohan Li, Xiao Xu, Xinghao Wang, Yutai Hou, Yunlong Feng | Summary: Existing image augmentation methods consist of two categories: perturbation-based methods and generative methods. Perturbation-based methods apply pre-defined perturbations to augment an original image, but only locally vary the image, thus lacking image diversity. In contrast, […]
