This paper reviews the available information on the central density distribution and shape of the Milky Way's halo. At present, there is no strong evidence that the Milky Way's halo properties conflict with the predictions of cold dark matter (CDM): a primordial central power law cusp can be accommodated by the observations, and the current constraints

Ultrafast Demagnetization Through Femtosecond Generation of Non‐Thermal Magnons
A fully ab initio parametrized model is developed to describe out‐of‐equilibrium magnon dynamics in ferromagnetic metals. Applying this model to ultrafast laser‐induced demagnetization, it is revealed that the generation of non‐thermal magnons provides a sizable demagnetization within 200 fs in excellent comparison with experiments, which establishes ...

Interfacing ferroelectric PbZr0.2Ti0.8O3 with ultrathin Sr2IrO4 tunes the antiferromagnetic Mott insulator into a 2D correlated metal. Switching the ferroelectric polarization induces nonvolatile, reversible resistance modulation in Sr2IrO4. The magnetoresisance in the heterostructure reveals the intriguing interplay of interfacial lattice coupling ...

A Multifaceted Spatial Analysis of Tomb Distribution in Blemmyan Berenike (Eastern Desert of Egypt)
ABSTRACT This study examines the spatial and visual organisation of tombs in the post–Roman Berenike located in Egypt's Eastern Desert. Archaeological surveys, remote sensing, geophysical methods, excavations and GIS‐based analyses are used for a comprehensive understanding of the spatial patterns and cultural significance behind the positions and ...

Thermal‐Infrared Measurements of the North‐East Tower at Ardrossan Castle
ABSTRACT Thermal‐infrared imaging of buildings is used to investigate a range of phenomena including the accumulation of moisture. In general, the presence of moisture poses a direct danger to historic structures and must be characterized prior to any intervention.
