Testing the limits of past-adapted explanations by post-endpoint randomisation: anticipatory EEG as a worked case
George Sopasakis, Alexandros Sopasakis
A predictive model can fit its data even when its information set is insufficient; fit alone cannot establish sufficiency. This Perspective introduces Level II-A, a new design-base…
Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: Resolved Stellar Populations Studies in M31 and its Satellites
C. Gallart, E. Fernández-Alvar, A. B. A. Queiroz +48
A 30 m class optical/near-IR telescope in the Northern Hemisphere, equipped for diffraction-limited imaging and high-resolution, multi-object spectroscopy of faint stars, would ena…
A Kinematic History of Stellar Encounters with Beta Pictoris
Jose Luis Gragera-Más, Santiago Torres, Alexander James Mustill +1
Beta Pictoris is an A-type star hosting a complex planetary system with two massive gas giants and a prominent debris disk. Variable absorption lines in its stellar spectrum have b…
Early Career Researcher Input to the European Strategy for Particle Physics Update: White Paper
Jan-Hendrik Arling, Alexander Burgman, Christina Dimitriadi +42
This document, written by early career researchers (ECRs) in particle physics, aims to represent the perspectives of the European ECR community and serves as input for the 2025--20…
Asymmetries in the LMC velocity maps
Marie Schölch, Ãscar Jiménez-Arranz, Mercè Romero-Gómez +4
The analysis of precise Gaia DR3 astrometry in the LMC region has revealed asymmetric patterns in the bar quadrupole and the disc outskirts of the LMC in-plane velocity maps. We ai…
Blind search for activity-sensitive lines in the near-infrared using HARPS and NIRPS observations of Proxima and Gl 581
João Gomes da Silva, Elisa Delgado-Mena, Nuno C. Santos +145
Stellar activity variability is one of the main obstacles to the detection of Earth-like planets using the RV method. The aim of this work is to measure the effect of activity in t…
