Hybrid Agents for Image Restoration

Kavli Affiliate: Li Xin Li | First 5 Authors: Bingchen Li, Xin Li, Yiting Lu, Zhibo Chen, | Summary: Existing Image Restoration (IR) studies typically focus on task-specific or universal modes individually, relying on the mode selection of users and lacking the cooperation between multiple task-specific/universal restoration modes. This leads to insufficient interaction for unprofessional […]

JWST’s First View of Tidal Disruption Events: Compact, Accretion-Driven Emission Lines & Strong Silicate Emission in an Infrared-selected Sample

Kavli Affiliate: Erin Kara | First 5 Authors: Megan Masterson, Kishalay De, Christos Panagiotou, Erin Kara, Anna-Christina Eilers | Summary: Mid-infrared (MIR) emission from tidal disruption events (TDEs) is a powerful probe of the circumnuclear environment around dormant supermassive black holes. This emission arises from the reprocessing of intrinsic emission into thermal MIR emission by […]

Measurement of the Branching Fraction of $Λ_c^+ to p K_S^0 π^0$ at Belle

Kavli Affiliate: T. Higuchi | First 5 Authors: The Belle, Belle II Collaborations, :, I. Adachi, L. Aggarwal | Summary: We report a precise measurement of the ratio of branching fractions $mathcal{B}(Lambda_c^+to p K_S^0 pi^0)/mathcal{B}(Lambda_c^+to p K^- pi^+)$ using 980 fb$^{-1}$ of $e^+e^-$ data from the Belle experiment. We obtain a value of $mathcal{B}(Lambda_c^+to p […]
