Tropical cyclones can produce extreme winds in the lowest portion of the boundary layer, posing high risks to critical energy infrastructure, including wind energy systems. This study evaluates the dynamic response of an idling wind turbine to turbulent inflow...

The unimolecular dynamics of Criegee intermediates depend strongly on their internal energy, which can differ substantially between nascent atmospheric species and laboratory-prepared reactants. Here, the decomposition dynamics of {\it anti-}CH$_3$CHOO are inv...

In the recent AI Model Intercomparison Project (AIMIP) benchmark, the ACE2.1-ERA5 emulator was shown to underestimate the true near-surface warming trend both during the training period and the out-of-sample extrapolation period. In this work, we present M-ACE...

Utilities request mutual aid crews to restore power after severe storms, and requesting early secures more crews but relies on less accurate forecasts. We examined how forecast lead time affects the value of outage predictions for crew deployment, using operat...

Urban hydrodynamic flood models typically rely on a surveyed terrain model, an explicit pipe drainage network, and rain gauge measurements, none of which were available for the inundation following Typhoon Matmo in My Dinh and Tay Mo, Hanoi, on 7 October 2025....

We characterize comet P/2026 N2, whose outer Main Belt orbit has $a=3.07$ au, $e=0.21$, and $i=2.25^\circ$, using optical observations, archival imaging, and dynamical integrations. Observations from the Legacy Survey of Space and Time (LSST) at NSF-DOE Vera C...

NASA's Kepler mission found more systems with one transiting planet (``singles'') than expected from those with several (``multis''). This excess was first taken as evidence for a Kepler dichotomy -- a second population of intrinsically single or highly inclin...

The shape of an exoplanet encodes fundamental information about its internal structure. For close-in giant planets, strong stellar tidal forces induce measurable deformations that can be probed through high-precision photometry. These deformations are quantifi...

Our understanding of complex organic chemistry during the formation of stars and planets is shaped by a handful of cherry-picked sources with bright molecular emission lines. This observational bias impedes our assessment of how universal chemical complexity i...

A growing number of transiting exoplanets exhibit spectroscopic evidence that their leading and trailing limbs differ. Interpreting these observations is now the limiting step. The standard approach of fitting limb-resolved transit depths results in highly ant...

We present a homogeneous analysis of 268 confirmed and candidate transiting hot-Jupiter host stars with 4800K < Teff < 6200K. We combine high-resolution TRES spectra, Gaia, 2MASS and WISE photometry, and Gaia astrometry to determine these stars' Teff, log g, R...

Water megamasers in the circumnuclear disks of active galactic nuclei are among the most precise probes of supermassive black holes. VLBI imaging of 22 GHz disk masers has provided geometric distances to independently constrain $H_0$, accurate black hole mass...
