Instrumentation and Methods for Astrophysics Papers of the Week

We report theoretical predictions and modeling of the far-wing absorption of CO2 broadened by He over a wide temperature range (200-1000 K), which are relevant for exoplanet atmosphere studies.

This paper introduces a framework for combining block-adaptive mesh refinement with block-local tensor-train representations of the photon specific intensity.

We propose science cases exploiting \textsc{SHARP}, a multi-mode near-infrared spectrograph for Extremely Large Telescopes and future space facilities.

We present the first search for fixed-polarization dark photon (DP) dark matter in the 44-52$\mu\mathrm{eV}$ mass range, corresponding to 10.7-12.5GHz.

We present, to our knowledge, the first learned surrogates of three-dimensional resistive MHD turbulence, and compare three standard backbones in that role: a convolutional UNet, a shifted-window transformer and a Fourier neural operator.

This paper introduces the physical architecture of the TART, describes it's electronics, radios, correlator, and the design of the antenna array.

In this study, we develop MP-DualNet, an end-to-end dual-branch deep learning framework for automated magnetopause detection from simulated SXI observations.

This setting gives rise to a natural machine learning problem: given observations of an object in some surveys, how to infer its appearance in other surveys. We formalize this as the problem of cross-survey modality imputation and introduce COSMIO, a multi-survey benchmark of aligned observations obtained by forward-rendered shared astrophysical scenes across LSST, Euclid, and Roman under survey-specific instrument characteristics.

We develop a unified framework that combines physical modeling with deep learning.

We present Finite-iteration Deconvolution--Reconvolution Denoising (FiDeR), a method for reducing noise in astronomical images while retaining approximately the input point-spread function (PSF).

We determine the best-fitting fPos through $\chi^2$ minimization and apply the method to astrometric data for the directly imaged PDS 70 and HR 8799 systems and to radial-velocity data for GJ 876.

Starting from Preston's law of material removal, we derive a first-principles explanation.

In this work, we aim to assess the capability of ET to detect orbital decay in hot Jupiters previously observed by Kepler.

This paper develops a restricted formal framework for estimating partial factual truth.

This paper introduces an improved Richardson--Lucy (RL) framework utilizing negative backfilling (NB) and the novel filtered image deconvolution and noise backfilling (FiDNoBa) algorithm.

We investigate the potential of the Ariel space telescope to detect and characterise exocomet transits through their wavelength-dependent photometric signatures.

We present auto_research, a semi-autonomous multi-agent pipeline that retrieves and analyses raw data from the High Energy Astrophysics Science Archive Research Center (HEASARC) and writes the analysis tools that it needs.

We develop a statistical approach to reconstruct the 2D distribution of the Galactic cirrus while preserving the underlying diffuse extragalactic emission from stellar halos.

We present ALMA and NOEMA observations of six CO isotopologue lines ($^{13}$CO, C$^{18}$O, and C$^{17}$O, $J$=2--1 and 1--0).
