A study of the large-scale formation in the environment of A3266: Infalling groups, filaments, and a premerger cold front

J. Dietl, A. Veronica, T. H. Reiprich +7

The paper uses eROSITA X‑ray data to map the outskirts of the galaxy cluster Abell 3266, revealing a hot X‑ray filament linking the cluster to a nearby group and showing how the cl…

Weighted Webs: Morphology-Informed Marked Fields

Mikel Martin Barandiaran, Jessica A. Cowell, David Alonso +2

The paper investigates how weighting the cosmic matter density field by morphological characteristics of the cosmic web (such as filamentarity and tidal shear) can enhance constrai…

Enabling Cosmic Web Analysis at Gigaparsec Scales: A Multi Block Approach for DisPerSE

Ankit Singh, Frazer Pearce, Meghan Gray +1

The paper introduces a frozen‑core, multi‑block technique that enables the DisPerSE filament finder to process gigaparsec‑scale cosmological simulations by preserving global topolo…

Alignment of the Milky Way and M31 with their cosmic environment. New insights from constrained Local Group simulations

Hanneke C. Woudenberg, Amina Helmi, Ewoud Wempe +4

Using constrained simulations that reproduce the observed Milky Way–Andromeda configuration, the authors examine how the surrounding Local Sheet influences the shapes, spins, and d…
