An Optimal Integral Controller for Adaptive Optics Systems
Sensors, 2023 Integral controllers are commonly employed in astronomical adaptive optics. This work presents a novel tuning procedure for integral controllers in adaptive optics systems which relies on information about the measured disturbances. This tuning procedure

Spectral Templates Optimal for Selecting Galaxies at z > 8 with the JWST
The Astrophysical Journal, 2023 The selection of high-redshift galaxies often involves spectral energy distribution (SED) fitting to photometric data, an expectation for contamination levels, and measurement of sample completeness—all vetted through comparison to spectroscopic redshift

Photometric Accuracy of Deconvolved Simulated Astronomical Images
The Astrophysical Journal, 2005 A study of the photometric accuracy of deconvolved astronomical images was undertaken by processing two simulated images with several well-known algorithms. The simulations consisted of an image of a simple star field and an image of an active galactic nucleus (AGN).

VLBI Network SIMulator: An Integrated Simulation Tool for Radio Astronomers
, 2018 In this paper we introduce a software package, the Very Long Baseline Interferometry Network SIMulator (VNSIM), which provides an integrated platform assisting radio astronomers to design the Very Long Baseline Interferometry (VLBI) experiments and evaluate the network performance with a user-friendly interface. Though VNSIM is motivated to be designed

DeepSurveySim: Simulation Software and Benchmark Challenges for Astronomical Observation Scheduling
DeepSurveySim: Simulation Software and Benchmark Challenges for Astronomical Observation Scheduling, 2023 Modern astronomical surveys have multiple competing scientific goals. Optimizing the observation schedule for these goals presents significant computational and theoretical challenges, and state-of-the-art methods rely on expensive human inspection of simulated telescope schedules.

A Lightweight Procedural Layer for Hybrid Experimental–Computational Workflows in Materials Science
Advanced Engineering Materials, EarlyView.We unveil a prototype hybrid‐workflow framework that fuses automatedcomputation with hands‐on experiments. Built atop pyiron, a lightweight, parameterized layer translates procedure descriptions into executable manual steps, syncing instrument settings, human interventions, and data capture in real‐time today.

Kinematic Evidence of an Embedded Protoplanet in HD 142666 Identified by Machine Learning
The Astrophysical Journal, 2023 Observations of protoplanetary disks have shown that forming exoplanets leave characteristic imprints on the gas and dust of the disk. In the gas, these forming exoplanets cause deviations from Keplerian motion, which can be detected through molecular ...
