Kavli Affiliate: Sara Seager | Summary:Small exoplanet radii show two populations, referred to as super-Earths and sub-Neptunes, separated by a gap known as the radius valley. This may be produced by the removal of atmospheres due to stellar or internal heating, or lack of an initial envelope. We us transit photometry and radial velocity measurements […]
Kavli Affiliate: Lijing Shao | Summary:The dense Galactic Center environment is expected to host compact binary inspirals detectable by future space-borne gravitational wave (GW) observatories (e.g., LISA, TianQin, Taiji) in the millihertz band. Aided by information from these facilities, next-generation ground-based GW detectors (e.g., Cosmic Explorer, Einstein Telescope) can potentially capture gravitational radiation in the […]

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 […]
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 […]
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 […]
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$_2$ […]
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 […]
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 […]
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 […]
