Controlling Grain Growth in Powder Bed Fusion of Yttria‐Stabilized Zirconia Using Femtosecond Lasers: Challenges and Methodological Insights

open access: yesAdvanced Engineering Materials, EarlyView.
Binder‐free laser powder bed fusion of 8YSZ with a femtosecond laser is used to map process windows linking scan strategy, heat accumulation, and grain growth. Time‐resolved thermography and simulations reveal thermal regimes that enable continuous, vitrified, and fine‐grained 8YSZ surface layers without absorptive additives and demonstrate ...

Impulsive Mixing of Stellar Populations in Dwarf Spheroidal Galaxies

open access: yesThe Astrophysical Journal
We study the response of mono-energetic stellar populations with initially isotropic kinematics to impulsive and adiabatic changes to an underlying dark matter potential.

Simulation‐Based Analysis of Insert Pull‐Out in Nickel‐Polyurethane Hybrid Foams Using CT‐Derived Geometries

open access: yesAdvanced Engineering Materials, EarlyView.
CT‐based finite element simulations combined with in situ X‐ray computed tomography are used to analyze insert pull‐out in nickel‐coated polymer foams. Despite variations in material parameters, deformation consistently concentrates within a narrow annular region around the insert.

Jormungandr: A Large Substructure Circling the Milky Way Identified from Gaia DR3 Data

open access: yesThe Astrophysical Journal
We report the discovery of a large substructure in the Milky Way passing through the solar neighborhood, detected in actions $\left({J}_{\phi },{J}_{{\rm{R}}}\right)$ calculated from Gaia DR3 data.

Probing Stellar Kinematics with the Time-Asymmetric Hanbury Brown and Twiss Effect

open access: yesThe Open Journal of Astrophysics
Intensity interferometry (II) offers a powerful means to observe stellar objects with a high resolution. In this work, we demonstrate that II can also probe internal stellar kinematics by revealing a time-asymmetric Hanbury Brown and Twiss (HBT) effect ...
