Kavli Affiliate: Erin Kara | First 5 Authors: Missagh Mehdipour, Jelle S. Kaastra, Megan E. Eckart, Liyi Gu, Ralf Ballhausen | Summary: We present our study of the XRISM observation of the Seyfert-1 galaxy NGC 3783. For the first time, XRISM’s Resolve microcalorimeter enables a detailed characterization of the highly ionized outflows in this active […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Yanjun Dai, Haoyang Feng, Yuan Gao, , | Summary: While online advertising is highly dependent on implicit interaction networks of anonymous users for engagement inference, and for the selection and optimization of delivery strategies, existing graph models seldom can capture the multi-scale temporal, semantic and higher-order dependency […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Aklant K. Bhowmick, Laura Blecha, Luke Z. Kelley, Aneesh Sivasankaran, Paul Torrey | Summary: We analyze the dynamics of low-mass black hole (BH) seeds in the high-redshift ($zgtrsim5$) Universe using a suite of $[4.5~mathrm{Mpc}]^3$ and $[9~mathrm{Mpc}]^3$ BRAHMA cosmological hydrodynamic simulations. The simulations form seeds with mass $M_{mathrm{seed}}=2.2times10^3~M_{odot}$ […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Haochen Wang, Panupong Phoompuang, Kiyoshi W. Masui, Arnab Chakraborty, Simon Foreman | Summary: Hybrid Foreground Residual Subtraction (HyFoReS) is a new family of algorithms designed to remove systematics-induced foreground contamination for 21-cm intensity mapping data. Previously, the algorithm was shown to be effective in mitigating beam […]
Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Senrui Chen, Akel Hashim, Noah Goss, Alireza Seif, Irfan Siddiqi | Summary: Noise is a major challenge for building practical quantum computing systems. Precise characterization of quantum noise is crucial for developing effective error mitigation and correction schemes. However, state preparation and measurement (SPAM) errors on many […]
Kavli Affiliate: Feng Wang | First 5 Authors: Zehong Ma, Longhui Wei, Feng Wang, Shiliang Zhang, Qi Tian | Summary: Existing acceleration techniques for video diffusion models often rely on uniform heuristics or time-embedding variants to skip timesteps and reuse cached features. These approaches typically require extensive calibration with curated prompts and risk inconsistent outputs […]
Kavli Affiliate: Kiyoshi Masui | First 5 Authors: Haochen Wang, Kiyoshi Masui, Shion Andrew, Emmanuel Fonseca, B. M. Gaensler | Summary: The dispersion of extragalactic fast radio bursts (FRBs) can serve as a powerful probe of the diffuse plasma between and surrounding galaxies, which contains most of the Universe’s baryons. By cross-correlating the dispersion of […]
Kavli Affiliate: Long Zhang | First 5 Authors: Peipei Lu, Mengju Yuan, Jing Zhang, Qiang Gao, Shuang Liu | Summary: In type-I superconductors, zero electrical resistivity and perfect diamagnetism define two fundamental criteria for superconducting behavior. In contrast, type-II superconductors exhibit more complex mixed-state physics, where magnetic flux penetrates the material above the lower critical […]
Kavli Affiliate: Menno Veldhorst | First 5 Authors: Pablo Cova Fariña, Daniel Jirovec, Xin Zhang, Elizaveta Morozova, Stefan D. Oosterhout | Summary: Quasi-particle dynamics in interacting systems in the presence of disorder challenges the notion of internal thermalization, but proves difficult to investigate theoretically for large particle numbers. Engineered quantum systems may offer a viable […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Li-Na Sheng, Geng Wang, Wei-Ping Chai, You-Jin Yuan | Summary: The construction of the High Intensity heavy ion Accelerator Facility (HIAF) has been completed, with current efforts focused on subsystem commissioning. Beam commissioning is scheduled for autumn 2025, marking a critical milestone in the HIAF […]
