Mesoscale Modelling of Titan's Shangri-La region: the impact of surface properties on winds
Maxence Lefèvre, Léa E. Bonnefoy, Aymeric Spiga +3
The knowledge of Titan's near-surface atmosphere is sparse. The Huygens descent probe measured winds, and the multiple dune field observations and possible dust storms suggest acti…
Geometry-Dependent Properties of Physically Crosslinked PPy-PVA Hydrogels Enable Tunable Iontophoretic Drug Delivery
Heather Jin Hee Kim, Mohsen Alishahi, Kyuin Park +3
Objective: Iontophoretic drug delivery has primarily relied on current modulation to regulate drug transport. Here, we investigate hydrogel geometry, microstructure, and local elec…

Superconducting weak links at substrate steps in bilayer nickelate films
Yidi Liu, Yaoju Tarn, Lopa Bhatt +6
Ambient-pressure superconductivity above 40 K has been realized in bilayer nickelate thin films on SrLaAlO (001), yet resistive measurements often exhibit incomplete zero-resis…
Monolayer van der Waals kagome lattice for high-temperature flat-band physics
Hyungkun Bong, Choongjae Won, Seongyong Lee +26
Kagome lattice materials host a remarkably rich landscape of novel quantum phenomena, all arising from the intrinsic interplay of topology, correlation, and frustration. While prev…
VHF Reconfigurable Intelligent Surfaces for Meteor Burst Communication
Rajiv Thummala, Luke Flores, Gregory Falco
Meteor Burst Communication (MBC) utilizes the transient ionized trails left by meteors to reflect Very High Frequency (VHF) signals, enabling long-range, beyond-line-of-sight commu…
The Science Potential of Characterizing Gas Giant Exoplanets with HWO
Beck Dacus, Jean-Baptiste Ruffio, Quinn Konopacky +19
With the ability to directly image Earth-like exoplanets and search their atmospheres for biosignatures, the upcoming Habitable Worlds Observatory (HWO) will also collect high sign…
The Nancy Grace Roman Space Telescope Coronagraph Community Participation Program
Dmitry Savransky, Vanessa P. Bailey, Schuyler G. Wolff +53
In preparation for the operational phase of the Nancy Grace Roman Space Telescope, NASA has created the Coronagraph Community Participation Program (CPP) to prepare for and execute…
High-Temperature ferromagnetism from site-selective filling in (Fe,Ni)GeTe
Tyler L. Werner, Jonathan T. Reichanadter, Xiang Chen +23
The discovery of high-temperature ferromagnetism in the metallic van der Waals (vdW) system FeGeTe has brought two-dimensional (2D) magnets into technologically relevant te…
Leveraging Impact Parameter to Mitigate the Transit Light Source Effect: Early Insights from TRAPPIST-1
Ana Glidden, Alexander I. Shapiro, Sara Seager +19
Stellar activity complicates exoplanet transmission spectra, particularly for smaller planets around M dwarfs with JWST. The transit light source (TLS) effect, the imprinting of sp…
Atmospheric Reconnaissance of TRAPPIST-1 f with JWST NIRISS SOSS: No Evidence for the Transit Light Source Effect
Olivia Lim, René Doyon, Ryan J. MacDonald +25
In just over three years of operation, JWST has observed all seven planets of the TRAPPIST-1 system. The two innermost planets were found to have little to no atmosphere, barring t…
A Three-Fluid Model of Dissipation at Surfaces in Superconducting Radiofrequency Cavities
Matthias Liepe Michelle M. Kelley, Sean Deyo, Nathan Sitaraman +4
Experiments on superconducting cavities have found that under large RF fields the quality factor can improve with increasing field amplitude, a so-called ``anti-Q slope.'' We numer…
Fabrication-free assessment of microwave losses in germanium-based dielectrics and superconductors
Haoran Lu, Kushagra Aggarwal, Xiangqin Wang +10
We present a flip-chip-based sensing scheme to measure effective microwave losses associated with target materials for quantum technologies, without requiring any device fabricatio…
The MegaWave Radio Surveyor
T. Joseph W. Lazio, Evgenya Shkolnik, James Aguirre +40
Several Decadal-level questions in astrophysics, exoplanets, astrobiology, and cosmology can be addressed only at low radio frequencies inaccessible from Earth. The MegaWave Radio…
CCAT: The Prime-Cam Instrument for the Fred Young Submillimeter Telescope -- Overview and Status
