Kavli Affiliate: David W. Miller | Summary:Open clusters are powerful laboratories for investigating the formation and evolution of white dwarfs (WDs), as their well-constrained ages link WDs to their progenitor stars. This is particularly valuable for atypical WDs, including magnetic WDs and those with non-hydrogen-dominated spectra, whose origins can be difficult to disentangle in the […]
Kavli Affiliate: Alan David Kaplan | Authors: Arghamitra Talukder and Alan Kaplan | Summary: Genomic foundation models promise to infer regulatory consequences of genetic variants directly from DNA sequence, but how well these predictions translate to clinical utility remains unclear. To probe this question, we evaluate AlphaGenome (AG) for understanding amyotrophic lateral sclerosis (ALS) genetics […]
Kavli Affiliate: Irfan Siddiqi | Summary:Dynamical protection via strong driving can enable resilient quantum processing on imperfect physical hardware. However, the practical utility of such schemes is frequently limited by parasitic processes such as drive-induced dephasing and leakage. Here, we demonstrate that sub-GHz charge driving of superconducting Kerr oscillators (KOs) in the transmon regime circumvents […]
Kavli Affiliate: Erin Kara | Summary:Quasi-periodic eruptions (QPEs) are repeating X-ray transients from galactic nuclei potentially caused by a stellar-mass orbiter repeatedly colliding with the accretion disk of a supermassive black hole (SMBH) in an extreme mass-ratio inspiral (EMRI). In this picture, the eruption arrival times encode the orbit and its relativistic precessions, while the […]
Kavli Affiliate: Huawei Zhang | Summary:Spatial audio signal enhancement (SASE) aims to separate a desired soundfield from interference and noise while preserving its spatial cues. However, existing algorithms pay limited attention to preserving the spatial cues of the residual interference, which reduces their effectiveness in practical applications. In this paper, we propose a direction-preserving SASE […]
Kavli Affiliate: Huawei Zhang | Summary:We propose a hybrid framework that combines deep learning with adaptive filtering for acoustic echo cancellation (AEC) and suppression. It integrates a multi-output neural network to jointly update filter parameters and perform post-processing. A learnable variant of the normalized least mean squares (NLMS) filter is introduced, incorporating a variable step […]
Kavli Affiliate: Archana Raja| Summary:When Coulomb interactions dominate kinetic energy, dilute two-dimensional carriers form a Wigner solid. Both its melting and disorder-driven localization can drive density-tuned metal-insulator transitions, but their relative roles and interplay have been debated for decades. Atomically thin semiconductors offer a new test because transport and scanning tunneling microscopy can probe the […]
Kavli Affiliate: Bradford Benson | Summary:We present a measurement of the spatial clustering of galaxy clusters selected via the thermal Sunyaev-Zel’dovich (tSZ) signal. Using a cluster catalog derived from five years of SPT-3G Main field survey data, we define a sample spanning $0.25 < z < 1.1$, as well as two subsamples spanning $0.25 < […]
Kavli Affiliate: Giordano Scappucci | Summary:Semiconductor-superconductor hybrid systems form the basis for a broad range of quantum phenomena, such as Andreev bound states, topological superconductivity, and hybrid quantum Hall states. The performance of these hybrid systems can strongly benefit from the exceptional electronic properties of heterostructures with deeply buried quantum wells. However, establishing high-quality superconducting […]
Kavli Affiliate: Kaisey Mandel | Summary:We present photometric and spectroscopic follow-up observations of the strongly-lensed H-poor superluminous supernova (SLSN) 2025wny at $z = 2.0155$. We use integral-field Keck-II/KCWI spectroscopy to obtain rest-frame ultraviolet spectra spanning $11$ to $61$ days after maximum light. We use Pan-STARRS photometry to constrain the brightest image’s magnification, finding $μ_A=19.4pm1.6$, a […]
