Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Calvin Leung, Calvin Leung, , , | Summary: Baryonic feedback is a leading contaminant in studying dark matter and cosmology using cosmic shear. This has meant omitting much of the data during cosmological inference, or forward-modeling the spatial distribution of gas around dark matter halos using […]
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Gordan Krnjaic, Gordan Krnjaic, , , | Summary: We study inelastic dark matter produced via freeze-in through a light mediator with a mass splitting below the electron-positron threshold. In this regime, the heavier dark matter state is naturally long-lived compared to the age of the Universe and […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Xuejian Shen, Xuejian Shen, , , | Summary: Early JWST observations have revealed a high-redshift universe more vibrant than predicted by canonical galaxy-formation models within $Lambda$CDM, showing an excess of ultraviolet(UV)-bright, massive, and morphologically mature galaxies. Departures from $Lambda$CDM prior to recombination can imprint signatures on non-linear […]
Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Kohei Inayoshi, Kohei Inayoshi, , , | Summary: The birth of seeds of massive black holes (BHs) and nascent galaxies at cosmic dawn takes place in dense gaseous environments, which play a crucial role in shaping their coevolution and radiation spectra. We investigate gas accretion during the […]
Kavli Affiliate: Jie Shan | First 5 Authors: Zhongdong Han, Zhongdong Han, , , | Summary: Quantum spin Hall insulators (QSHIs) and excitonic insulators (EIs) are prototypical topological and correlated states of matter, respectively. The topological phase transition between the two has attracted much theoretical interest but experimental studies have been hindered by the availability […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Bingnan Li, Bingnan Li, , , | Summary: Despite steady progress in layout-to-image generation, current methods still struggle with layouts containing significant overlap between bounding boxes. We identify two primary challenges: (1) large overlapping regions and (2) overlapping instances with minimal semantic distinction. Through both qualitative examples […]
Kavli Affiliate: Wei Gao | First 5 Authors: Xiaolei Li, Xiaolei Li, , , | Summary: This paper proposes an orthogonality-constrained modal search (OCMS) method for estimating modal wavenumbers and modal depth functions using a vertical linear array (VLA). Under the assumption of a known sound speed profile, OCMS leverages the orthogonality of distinct modal […]
Kavli Affiliate: Long Zhang | First 5 Authors: Lingwen Deng, Lingwen Deng, , , | Summary: Parameter-Preserving Knowledge Editing (PPKE) enables updating models with new or corrected information without retraining or parameter adjustment. Recent PPKE approaches based on knowledge graphs (KG) to extend knowledge editing (KE) capabilities to multi-hop question answering (MHQA). However, these methods […]
Kavli Affiliate: Sunil R. Golwala | First 5 Authors: Brandon J. Sandoval, Brandon J. Sandoval, , , | Summary: Phonon sensitive superconducting qubits promise to provide sub-eV energy deposit thresholds, useful for future rare-event experiments looking for interactions from dark matter and neutrinos. We detail here engineering results from a Quantum Parity Detector (QPDs), one […]
