A Framework for Ultralow Surface-brightness Integral-field-unit Emission Mapping with the Keck Cosmic Web Imager

open access: yesThe Astronomical Journal
Detecting spatially resolved emission at surface-brightness levels of ∼10 ^−20 –10 ^−19  erg cm ^−2  s ^−1  arcsec ^−2  Å ^−1 in optical integral-field spectroscopy requires reduction procedures limited not by photon statistics, but by systematic effects

Multispectral UV Imaging on Capacitive CMOS Arrays Enabled by Solution‐Processed Metal‐Oxide Nanoparticles

open access: yesAdvanced Science, EarlyView.
Ultraviolet (UV) imagers are important for a variety of applications but often require dedicated semiconductor process flows. Here, a versatile capacitive CMOS platform is transformed into a visible‐blind, multispectral UV imager through post‐CMOS functionalization with solution‐processed metal‐oxide nanoparticles. The UV‐induced photodielectric effect

Data-Rich Astronomy: Mining Synoptic Sky Surveys

open access: yes, 2015
In the last decade a new generation of telescopes and sensors has allowed the production of a very large amount of data and astronomy has become, a data-rich science; this transition is often labeled as: "data revolution" and "data tsunami".

Searching for Short-period Variables in M31: Method and Catalogs

open access: yesThe Astrophysical Journal Supplement Series
Utilizing high-cadence and continuous g - and r -band data over three nights acquired from the 3.6 m Canada–France–Hawaii Telescope, aiming to find short-duration microlensing events, we conduct a systematic search for variables, transients, and ...

Scalable Crackle‐Lithography for Multifunctional Enclosed Plastic Nanofluidic Devices

open access: yesAdvanced Science, EarlyView.
Crackle‐lithography enables scalable fabrication of enclosed plastic‐substrate‐based nanofluidic devices with interconnected nanochannels that enable molecular transport, optical interrogation, confined electroless copper deposition, and ionic memristive behavior.

Data-driven Radiative Hydrodynamics Simulations of the Solar Photosphere Using Physics-informed Neural Networks: Proof of Concept

open access: yesThe Astrophysical Journal
Current, realistic numerical simulations of the solar atmosphere reproduce observations in a statistical sense; they do not replicate observations such as a movie of solar granulation.

Synergies between exoplanet surveys and variable star research

open access: yesEPJ Web of Conferences, 2017
With the discovery of the first transiting extrasolar planetary system back in 1999, a great number of projects started to hunt for other similar systems. Because the incidence rate of such systems was unknown and the length of the shallow transit events

Observation of Magnetic‐Anisotropy Crossover and High‐Temperature Skyrmions in the Dirac Magnet Fe3Ge with a Distorted Kagome Lattice

open access: yesAdvanced Science, EarlyView.
A temperature‐driven magnetic anisotropy crossover is revealed in the Dirac kagome magnet Fe3Ge with a distorted kagome lattice. The transition from easy‐plane to easy‐axis magnetic anisotropy stabilizes robust Bloch‐type skyrmions over an exceptionally wide temperature window of 375–650 K.

SIMLA: The Spitzer Infrared Spectrograph Mapping Legacy Archive

open access: yesThe Astrophysical Journal Supplement Series
We present the Spitzer/IRS Mapping Legacy Archive (SIMLA); a complete set of mid-infrared spectral cubes built from low-resolution mapping-mode fixed-target observations from the Spitzer Infrared Spectrograph (IRS; 5.2–38 μ m, R ∼ 60–130).

Quantum‐Trained AI Enables Inverse Design of Organic Frontier Orbitals at Billion‐Scale

open access: yesAdvanced Science, EarlyView.
Quantum‐trained AI links molecular substructures to frontier‐orbital energetics and enables interpretable screening across nearly one billion GDB‐13 molecules. By combining fragment‐ and ring‐level insights with donor–acceptor energy alignment against ITIC, the framework narrows an immense chemical space to a small set of promising candidates and ...
