Latent-centric Isotropic Resolution Enhancement for Expansion Microscopy Imaging via Neural Compression and Self-supervised Learning

Posted by dbos February 10, 2026February 23, 2026UCSD / Salk

Kavli Affiliate: Ann-Shyn Chiang | Authors: Pin-Hsun Lian, Tzu-Yi Chuang, Ya-Ding Liu, Li-An Chu, Sheng-Cheng Chang, Yu-Chen Kuo, Wei-Kun Chang, Ann-Shyn Chiang and Gary Chang | Summary: Expansion microscopy (ExM) enables nanoscale imaging for disease characterization. However, whole-organ analyses remain limited by several challenges. Current super-resolution methods either require high-resolution ground-truth data or assume spatially […]

Field-driven Ion Pairing Dynamics in Concentrated Electrolytes

Posted by klaurent February 10, 2026February 23, 2026Berkeley

Kavli Affiliate: David T. Limmer | Summary:We investigate ion pairing dynamics in electrolytes driven far from equilibrium using molecular simulations and nonequilibrium rate theory. Focusing on 0.5 M $mathrmLiPF_6$ in water and acetonitrile under uniform electric fields, we compute transition path theory observables including reactive fluxes and mean first-passage times of ion pairing. Moreover, we […]

Keck Observations in the INfrared of Taurus and $ρ$ Oph Exoplanets And Ultracool dwarfs (KOINTREAU) II: Two Young Bound Companions to Ophiuchus Stars

Posted by klaurent February 10, 2026Caltech

Kavli Affiliate: Dimitri Mawet| Summary:We present the second set of discoveries from Keck Observations in the INfrared of Taurus and $ρ$ Oph Exoplanets And Ultracool dwarfs (KOINTREAU), an adaptive optics survey of young stars in the Taurus and $ρ$ Oph star-forming regions using Keck/NIRC2 in conjunction with the Keck infrared pyramid wavefront sensor. We have […]

Relativistic Effects in LaBi$_2$ Thin Films

Posted by klaurent February 10, 2026February 23, 2026Caltech

Kavli Affiliate: Joseph Falson | Summary:Chemical substitution in crystalline quantum materials is a powerful way to explore the consequences of strong spin-orbit coupling on their structural and electronic properties. In this work, we present an investigation of thin films of the La$textitPn_2$ ($textitPn$~=~Sb, Bi) class of layered square-net intermetallics. We report the growth of LaBi$_2$ […]

A Deep Precursor-Dip-Main Superoutburst Sequence in VW Hydri Observed with TESS: High-Cadence Constraints on the Thermal-Tidal Instability Model

Posted by klaurent February 10, 2026February 23, 2026MIT

Kavli Affiliate: Avi Shporer | Summary:We present 120s cadence TESS observations of three superoutbursts of the SU UMa-type dwarf nova VW Hydri. Two events (SO2 in Sectors 87+88 and SO3 in Sector 93) exhibit a pronounced, temporally pronounced precursor-dip followed by a rapid rise into the main superoutburst plateau. This morphology, previously seen in Kepler […]

Microlensing events and primordial black holes in the axionlike curvaton model

Posted by klaurent February 10, 2026February 23, 2026Tokyo

Kavli Affiliate: Masahiro Kawasaki | Summary:Recently, Subaru Hyper Suprime-Cam (HSC) observations found 12 candidates for microlensing events. These events can be explained by primordial black holes (PBHs) with masses of $10^-7$-$10^-6 M_odot$ and a fraction of all dark matter of $f_mathrmPBH = mathcalO(10^-1)$. In this paper, we consider the PBH production in two types of […]

The compositions of the HR 8799 planets reflect accretion of both solids and metal-enriched gas

Posted by klaurent February 10, 2026Caltech

Kavli Affiliate: Dimitri Mawet| Summary:With four giant planets ($msim5-10~M_rm Jup$, $T_rmeffsim900-1200$ K) orbiting between 15-70 au, HR 8799 provides an unparalleled testbed for studying giant planet formation and probing compositional trends across the protoplanetary disk. We present new JWST/NIRSpec IFU observations ($2.85-5.3~μ$m, $Rapprox2700$) that now include the spectrum of HR 8799 b, and higher S/N […]

Mass-Radius Constraints for 2S 0918-549 from an RXTE Superexpansion Burst: A Direct Cooling-Tail Analysis

Posted by klaurent February 10, 2026February 23, 2026Peking

Kavli Affiliate: Renxin Xu | Summary:Thermonuclear (Type I ) X-ray bursts from accreting neutron stars offer a means to determine neutron-star (NS) mass ($M$) and radius ($R$) and thereby probe the properties of matter at supranuclear density. A subset of these events, photospheric radius-expansion (PRE) bursts, provide a particularly powerful tool to constrain the neutron-star […]

A proof of Dolbeault geometric Langlands for $mathrmGL_2$ with reduced spectral curves

Posted by klaurent February 10, 2026Tokyo

Kavli Affiliate: Yukinobu Toda | Summary:In our previous paper with Tudor Pădurariu, we introduced the notion of limit categories for moduli stacks of Higgs bundles and formulated the Dolbeault geometric Langlands correspondence. These limit categories are expected to provide an effective “classical limit” of the categories of D-modules on the moduli stack of bundles, and […]
