Multi-modal strain mapping of steel crack tips with micrometer spatial resolution
Ahmar Khaliq, Felix Wittwer, Markus Hartmann +6
Due to their superior fatigue strength, martensitic steels are the material of choice for high cyclic loading applications such as coil springs. However, crack propagation is influ…
Spatial and kinematic segregation in star cluster merger remnants
David R. Cole, Victor P. Debattista, Anna Lisa Varri +2
Globular clusters which exhibit chemical and dynamical complexity have been suggested to be the stripped nuclei of dwarf galaxies (e.g., M54, Cen). We use -body simulations…
Texture tomography with high angular resolution utilizing sparsity
Mads Carlsen, Florencia Malamud, Peter Modregger +5
We demonstrate a novel approach to the reconstruction of scanning probe x-ray diffraction tomography data with anisotropic poly crystalline samples. The method involves reconstruct…
Deepfakes in Criminal Investigations: Interdisciplinary Research Directions for CMC Research
Lorenz Meinen, Astrid Schomäcker, Stefanie Wiedemann +5
The emergence of deepfake technologies offers both opportunities and significant challenges. While commonly associated with deception, misinformation, and fraud, deepfakes may also…
Constraining the role of star cluster mergers in nuclear cluster formation: Simulations confront integral-field data
Markus Hartmann, Victor P. Debattista, Anil Seth +2
We present observations and dynamical models of the stellar nuclear clusters (NCs) at the centres of NGC 4244 and M33. We then compare these to an extensive set of simulations test…
The effect of bars on the M-sigma relation: offset, scatter and residuals correlations
Markus Hartmann, Victor P. Debattista, David R. Cole +3
We analyse a set of collisionless disc galaxy simulations to study the consequences of bar formation and evolution on the M-sigma relation of supermassive black holes. The redistri…
