Variable X-ray reverberation in the rapidly accreting AGN Ark 564: the response of the soft excess to the changing geometry of the inner accretion flow

Posted by klaurent July 22, 2025August 4, 2025Stanford

Kavli Affiliate: Steven W. Allen | First 5 Authors: Zhefu Yu, Zhefu Yu, , , | Summary: X-ray reverberation, which exploits the time delays between variability in different energy bands as a function of Fourier frequency, probes the structure of the inner accretion disks and X-ray coronae of active galactic nuclei. We present a systematic […]

Stellar Mass-Dispersion Measure Correlations Constrain Baryonic Feedback in Fast Radio Burst Host Galaxies

Posted by klaurent July 22, 2025August 4, 2025MIT

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Calvin Leung, Calvin Leung, , , | Summary: Low redshift fast radio bursts (FRBs) provide robust measurements of the host-galaxy contribution to the dispersion measure (DM), which can constrain the circumgalactic medium (CGM) of the hosts. We curate a sample of 20 nearby FRBs with low […]

WGRAMMAR: Leverage Prior Knowledge to Accelerate Structured Decoding

Posted by klaurent July 22, 2025August 4, 2025Peking

Kavli Affiliate: Ran Wang | First 5 Authors: Ran Wang, Ran Wang, , , | Summary: Structured decoding enables large language models (LLMs) to generate outputs in formats required by downstream systems, such as HTML or JSON. However, existing methods suffer from efficiency bottlenecks due to grammar compilation, state tracking, and mask creation. We observe […]

EarthCrafter: Scalable 3D Earth Generation via Dual-Sparse Latent Diffusion

Posted by klaurent July 22, 2025August 4, 2025Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Shang Liu, Shang Liu, , , | Summary: Despite the remarkable developments achieved by recent 3D generation works, scaling these methods to geographic extents, such as modeling thousands of square kilometers of Earth’s surface, remains an open challenge. We address this through a dual innovation in data […]

STAR: A Benchmark for Astronomical Star Fields Super-Resolution

Posted by klaurent July 22, 2025August 4, 2025Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Kuo-Cheng Wu, Kuo-Cheng Wu, , , | Summary: Super-resolution (SR) advances astronomical imaging by enabling cost-effective high-resolution capture, crucial for detecting faraway celestial objects and precise structural analysis. However, existing datasets for astronomical SR (ASR) exhibit three critical limitations: flux inconsistency, object-crop setting, and insufficient data diversity, […]

The THESAN project: environmental drivers of Local Group reionization

Posted by klaurent July 22, 2025August 4, 2025MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Yu Zhao, Yu Zhao, , , | Summary: The timing of cosmic reionization across Local Group (LG) analogues provides insights into their early histories and surrounding large-scale structure. Using the radiation-hydrodynamic simulation THESAN-1 and its dark matter-only counterpart THESAN-DARK-1, we track the reionization histories of all haloes, […]

Optimal schedule of multi-channel quantum Zeno dragging with application to solving the k-SAT problem

Posted by klaurent July 22, 2025Berkeley

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Yipei Zhang, Yipei Zhang, , , | Summary: Quantum Zeno dragging enables the preparation of common eigenstates of a set of observables by frequent measurement and adiabatic-like modulation of the measurement basis. In this work, we present a deeper analysis of multi-channel Zeno dragging using generalized measurements, […]

Increased Exertion Variability is Linked to Disruptions in Effort Assessment in Multiple Sclerosis

Posted by dbos July 21, 2025August 4, 2025Hopkins

Kavli Affiliate: Vikram Chib | Authors: Michael H Dryzer, Bardia Nourbakhsh, Jennifer Keller and Vikram S. Chib | Summary: Accurate assessment of exertion is crucial for determining whether to continue or rest during physical activity. Individuals with multiple sclerosis (MS) often report fatigue and motor impairments, yet the mechanisms underlying their assessments of effortful exertion […]

A Partially Massless Superconductor

Posted by klaurent July 21, 2025August 4, 2025Chicago

Kavli Affiliate: Austin Joyce | First 5 Authors: Kurt Hinterbichler, Kurt Hinterbichler, , , | Summary: We describe a Higgs mechanism for the partially massless graviton. In order to do so, we first construct a covariant fracton-like effective field theory on de Sitter space that linearly realizes a dipolar shift symmetry. The global symmetry of […]
