The superb image quality, stability, and sensitivity of JWST permit deconvolution techniques to be pursued with a fidelity unavailable to ground-based observations. We present an assessment of several deconvolution approaches to improve image quality and mitigate the effects of the complex JWST point-spread function (PSF). The optimal deconvolution

Dynamical Architectures of S-type Transiting Planets in Binaries. I. Target Selection Using Hipparcos and Gaia Proper Motion Anomalies
The effect of stellar multiplicity on planetary architecture and orbital dynamics provides an important context for exoplanet demographics. We present a volume-limited catalog of up to 300 pc of 66 stars hosting planets and planet candidates from Kepler, K2, and TESS with significant Hipparcos-Gaia proper motion anomalies, which indicates theZhang, Jingwen et al.
Optimal 1D Ly α forest power spectrum estimation - III. DESI early data
The 1D power spectrum P1D of the Ly α forest provides important information about cosmological and astrophysical parameters, including constraints on warm dark matter models, the sum of the masses of the three neutrino species, and the thermal state of the intergalactic medium. We present the first measurement of P1D with the quadratic maximumKaraçaylı, Naim Göksel et al.
Strategies for optimal sky subtraction in the low surface brightness regime
The low surface brightness (LSB) regime (μg ≳ 26 mag arcsec-2) comprises a vast, mostly unexplored discovery space, from dwarf galaxies to the diffuse interstellar medium. Accessing this regime requires precisely removing instrumental signatures and light contamination, including, most critically, night sky emission. This is not trivial, as faintWatkins, Aaron E. et al.
PRIMASS near-infrared study of the Erigone collisional family
Past analyses of spectral properties of the inner-belt primitive families in visible wavelengths have uncovered the possible existence of two compositional groups: Erigone-like (highly hydrated) and Polana-like (nearly anhydrous) (Morate et al., 2018). We explore the spectral properties of the Erigone asteroid family in the near-infrared to probeHarvison, Brittany et al.
Constraints on axion-like particles with the Perseus Galaxy Cluster with MAGIC
Axion-like particles (ALPs) are pseudo-Nambu-Goldstone bosons that emerge in various theories beyond the standard model. These particles can interact with high-energy photons in external magnetic fields, influencing the observed gamma-ray spectrum. This study analyzes 41.3 h of observational data from the Perseus Galaxy Cluster collected with theAbe, H. et al.
