The PAU Survey: Self-supervised image denoising for flux-preserving photometry
Deep photometric surveys increasingly rely on low signal-to-noise imaging, where noise affects source detection, flux measurements, photometric redshifts, and sample selection.On the Detectability of Compact Multi-Planet Systems via Gravitational Microlensing
Compact multi-planet systems orbiting ultracool dwarfs, such as TRAPPIST-1, may be a major population of terrestrial worlds with poorly constrained demographics.Harmonic Angular Mapping Method for Binary Microlensing Grid Search
Searching for binary-lens microlensing solutions is computationally demanding because of the complex parameter space and the large number of trial models required.Statistical Modeling of Foreground Galactic Cirrus for Diffuse Halo Light Measurement
Galactic cirrus, the diffuse Milky Way starlight scattered by interstellar dust, has become a major source of systematic uncertainty in measurements of extragalactic diffuse emission at ultra-low…Anomaly-ranked confirmation slows new-class learning
Anomaly detectors rank unfamiliar examples for expert confirmation, and the confirmed examples teach a classifier to recognise a new class.From Rock Tumbling to Telescope Mirror Grinding: How Optical Perfection Emerges from Random Motion
When two glass disks are rubbed together by hand with an abrasive between them, their surfaces spontaneously converge to perfectly matching spherical curves, accurate to tens of nanometers.Simulating winds in the Galactic centre. II. Observational biases on HI clouds and a multi-wavelength comparison
High-velocity neutral hydrogen (HI) clouds found up to several kiloparsecs above the Galactic centre (GC) provide some of the most direct evidence for a nuclear wind in the Milky Way, yet the…Learned Surrogates of Three-Dimensional Magnetohydrodynamic Turbulence
Three-dimensional magnetohydrodynamic (MHD) turbulence, the flow of astrophysical and fusion plasmas, is costly to simulate.Spectral Information Content of Diffraction-Limited Images
High-resolution optical imaging is fundamentally limited by diffraction, which imprints wavelength-dependent structure onto the point spread function (PSF) of the optical system.Cryogenic Optical Characteristics of S-FPL51 and S-LAH71: Refractive index, Transmission and Thermal expansion
Several near-infrared instruments on upcoming extremely large telescopes use a combination of OHARA S-FPL51 and S-LAH71 glass prisms to correct for the atmospheric differential refraction.Contrastive Astromer: Two-Stage Contrastive Representation Learning for Astronomical Light Curve Classification
Large astronomical surveys collect abundant light curves, but reliable class labels remain scarce.The Korean Space Telescope (KST): A Dedicated Space Observatory for the Dark Universe
The Korean Space Telescope (KST) is a next-generation 1.4-meter wide-field space observatory, a dedicated probe of the dark sector.On the Proper 3D Modeling of Orbits in Wide Binary Gravity Tests
A gravitationally-bound system of wide binary stars with precise 3D relative displacement $\mathbf{r}$ and velocity $\mathbf{v}$ can allow a Keplerian orbit reconstruction for an assumed…OCCAMS: A Multi-Task Learning-Based Investigation of the CMB Power Spectra
How many latent variables are needed to fit the cosmic microwave background (CMB) temperature and polarisation power spectra when a neural network is given no cosmological model, and to what extent…The unresolved high-mass frontier of the black hole Fundamental Plane
Accreting black holes follow a Fundamental Plane (FP) linking radio and X-ray luminosities to black hole mass, but whether this relation changes in the ultramassive regime, above…PyMsOfa 2.0: A Pure-Python Implementation of the IAU Standards of Fundamental Astronomy Service
Astrometric calculations require authoritative algorithms so that every result is correct and reproducible.GRAVITY-RESOLVE: A comprehensive image reconstruction tool for Galactic Center observations with GRAVITY
We aim to improve and extend the imaging capabilities of the GRAVITY beam combiner instrument of ESOs VLTI with respect to reconstruction software in the Galactic Center.UnEZ: A Fully Unsupervised Self-Templating Neural Network for Redshift and Line Strength Estimation
As spectroscopic surveys grow, estimating galaxy properties such as metallicity, star formation rate, and redshift becomes computationally cumbersome.A Hierarchical Bayesian Differential Calibration of the Gaia DR3 Parallax Zero Point Using Galactic Globular Clusters
Globular clusters (GCs) occupy a broad range of stellar colors and magnitudes while sharing nearly the same distance.Quantum Annealing for Gamma-ray Source Detection and Localization with AGILE Data
The detection and localization of gamma-ray sources via maximum-likelihood analysis is a complex parameter optimization problem.
