Kavli Affiliate: George Efstathiou | Summary:We provide an overview of the eight SKAO Science Book chapters that motivate the Epoch of Reionisation and Cosmic Dawn experiments with SKA-Low. We describe the individual SKA-Low experiments and expected sensitivity – power spectrum, tomography, 21-cm forest, cross-correlations, building on the broad observational plan laid out in the 2015 […]
Kavli Affiliate: Wei Gao| Summary:Multi-fingered robots promise the speed and dexterity of human hands, yet challenging problems such as precise assembly have remained out of reach. These tasks are contact-rich, making data collection for imitation learning difficult, and sparse-reward, making direct exploration with reinforcement learning (RL) intractable. Consequently, prior work has made progress by structuring […]

Kavli Affiliate: Alex Kolodkin | Authors: Stephanie L Sarbanes, Jakub Ziak, Alex L Kolodkin and Antonina Roll-Mecak | Summary: Microtubule dynamics regulation is critical for neuronal development, yet how neurons regulate tubulin levels remains poorly understood. Tetratricopeptide repeat domain 5 (TTC5) mediates the co-translational degradation of tubulin transcripts in response to excess soluble tubulin, a.k.a. […]
Kavli Affiliate: Sunil Golwala | Summary:As SuperCDMS SNOLAB is getting ready to search for low mass dark matter particles, using cryogenic Ge and Si detectors, a set of six of the new SuperCDMS High Voltage (HV) detectors (four Ge and two Si) were tested in the Cryogenic Underground TEst facility (CUTE) at SNOLAB. This provided […]
Kavli Affiliate: Kiyoshi Masui | Summary:The recent release of CHIME/FRB Catalog~2 provides the largest sample to date with which to investigate the intrinsic distributions of fast radio bursts (FRBs). Leveraging an expanded campaign of 587,367 synethetic bursts injected into the live CHIME/FRB search pipeline, we perform a population analysis of the fluence, scattering timescale, pulse […]
Kavli Affiliate: Jinyi Shangguan | Summary:Detections of protoplanets are rare and protoplanetary disk features mischaracterized as planets are common. PDS 70 is one of only two stars known to host multiple confirmed protoplanets, PDS 70 b and c, and repeat detections of a third point-like source in the system suggest the presence of third inner […]

Kavli Affiliate: David T. Limmer | Summary:Odd diffusion is a hallmark of chiral active matter, generating currents transverse to density gradients. Existing theories rely on a linear antisymmetric transport coefficient that exists only in two dimensions, raising the question of whether odd diffusion can occur in isotropic three-dimensional systems. Here we show that such transport […]
Kavli Affiliate: Lina Necib | Summary:The density profiles of dwarf spheroidal galaxies are among the most sensitive probes of dark matter physics, yet extracting them from noisy stellar kinematics remains a fundamental obstacle. We present GraphNPE, a simulation-based inference method for dynamical mass modeling that incorporates measurement uncertainties and spectroscopic selection functions in the forward […]
