First Constraints on Helium +He3 Evolution in z = 3–4 Using the 8.67 GHz Hyperfine Transition
The Astrophysical Journal, 2023 We present the first constraints on the cross-correlation power spectrum of the He ii ( ^+ He ^3 ) signal strength using the redshifted 8.67 GHz hyperfine transition between z = 2.9 and 4.1 and with interferometric data obtained from the public archive ...

The GRAVITY fringe tracker: correlation between optical path residuals and atmospheric parameters
, 2018 After the first year of observations with the GRAVITY fringe tracker, we compute correlations between the optical path residuals and atmospheric and astronomical parameters. The median residuals of the optical path residuals are 180 nm on the ATs and 270

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.
