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 […]
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 […]
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 […]
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, […]
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 […]
Kavli Affiliate: Naoki Yasuda | First 5 Authors: Weiyu Wu, Weiyu Wu, , , | Summary: In recent years, with an increasing number of type Ia supernovae (SNe Ia) discovered soon after their explosions, a non-negligible fraction of SNe Ia with early-excess emissions (EExSNe Ia) have been confirmed. In this letter, we present a total […]
Kavli Affiliate: Sven Herrmann | First 5 Authors: Piotr Maj, Piotr Maj, , , | Summary: We present a Virtual Frisch-Grid geometry-based CZT gamma detector developed for identifying different radioisotopes over an energy range from single keV up to 2 MeV, and useful for efficient characterization of CZT crystals. The detector is built with a […]
Kavli Affiliate: Hu Zhan | First 5 Authors: Huai-Jin Tang, Huai-Jin Tang, , , | Summary: It is projected that more than 100,000 communication satellites will be deployed in Low-Earth Orbit (LEO) over the next decade. These LEO satellites (LEOsats) will be captured frequently by the survey camera onboard the China Space Station Telescope (CSST), […]
Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Kazuki Kannaka, Kazuki Kannaka, , , | Summary: Let $X=G/H$ be a homogeneous space, where $G supset H$ are reductive Lie groups. We ask: in the setting where $Gamma backslash G/H$ is a standard quotient, to what extent can the discrete subgroup $Gamma$ be deformed while preserving […]
Kavli Affiliate: Kejia Lee | First 5 Authors: Dengke Zhou, Dengke Zhou, , , | Summary: Possible periodic features in fast radio bursts (FRBs) may provide insights into their astrophysical origins. Using extensive observations from the Five-hundred-meter Aperture Spherical radio Telescope (FAST), we conduct a search for periodicity across multiple timescales in the exceptionally active […]
