Distribution and Kinematics of Classical Cepheids in the Galactic Outer Ring
Open Astronomy, 2015 The existence of an outer ring in the Galaxy can explain the kinematics of OB associations in the Perseus and Sagittarius stellar-gas complexes. Moreover, it can also explain the orientation of the Carina arm with respect to the major axis of the bar. We

On the Structure of Galaxy Clusters
, 2007 I summarise the state of the scientific exploration of the structure of galaxy clusters and present two new studies, namely, I propose and test a novel method to model clusters by a joint X-ray, thermal Sunyaev-Zeldovich and lensing analysis, and I investigate the impact of baryonic physics on strong cluster lensing and cluster structure.

Synergies in Self‐Assembly—From Supramolecular Polymers to Defined Hierarchical Superstructures
Journal of Polymer Science, EarlyView.Shaping supramolecular polymers built from molecular building blocks into superstructures with defined dimensions. Synergies within supramolecular architectures such as chirality or an additional second orthogonal driving force that does not interfere with the central supramolecular motif facilitate the confinement of the growth of these ...

Effects of Galactic Irradiation on Thermal and Electronic Transport in Tungsten
physica status solidi (b), EarlyView.This atomic‐scale study reveals how low‐to‐mid‐energy space irradiation alters tungsten's thermal and electronic behavior, even at low defect levels. Focusing on vacancy sites in bulk and near grain boundaries, it employs two novel approaches: site‐projected thermal conductivity and the N2$^{2}$ method for the thermal and electronic response analysis ...

Structure of Dark Matter in Galaxies [PDF]
, 2004 The origin, nature and distribution of dark matter in the universe form some of the biggest questions in modern astrophysics. Dark matter is distributed on a wide range of scales in the universe. This thesis concentrates on galactic scales, attempting to lower the veil and probe the structure of dark matter in galaxies.

Prioritized Real‐Time UAV‐Based Vessel Detection for Efficient Maritime Search
Journal of Field Robotics, EarlyView.ABSTRACT Real‐time vessel detection in maritime environments is crucial for diverse applications requiring speed and accuracy. Static camera views often introduce blind spots, compromising detection efficiency. This paper proposes a novel, real‐time UAV‐based system that uses a dynamic camera control strategy to address this limitation.
