Swift Follow-up of Reported Radio Pulsars at Fermi 4FGL Unassociated Sources

The Astrophysical Journal, 2023
Following the discovery of radio pulsars at the position of Fermi-LAT unassociated sources by the TRAPUM group, we conduct Swift-XRT observations of six of those 4FGL sources to determine if any pulsar-like X-ray sources are present and to confirm the ...

Selective Hydrogenation of 1‐Indanone to 1‐Indanol near Room Temperature Catalyzed by Immobilized Pt‐Nanoparticles on SBA‐15

ChemCatChem, Volume 17, Issue 16, August 18, 2025.
This study presents a sustainable method of producing 1‐indanol at room temperature via the selective reduction of the C = O bond in 1‐indanone using Pt/SBA‐15 catalysts and green hydrogen. Using n‐decane as a carrier liquid, the process efficiently converts the substance under ambient conditions.

On the soft emission mechanism in X-ray pulsars

Journal of Theoretical and Applied Physics, 2019
We propose a mechanism responsible for the soft emission in X-ray pulsars. We discuss the origin of the soft emission for isolated X-ray pulsars as well as for soft gamma-ray repeaters and anomalous X-ray pulsars.

Two Micron‐Size Dark Dimensions

Fortschritte der Physik, Volume 73, Issue 8, August 2025.
Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

Maximum Mass Limit of Generalized MIT Compact Star: A Theoretical Study of Thin Shell Dynamics and Gravitational Lensing

Fortschritte der Physik, Volume 73, Issue 8, August 2025.
Abstract In this study, the properties, equilibrium, and stability of compact objects within the framework of teleparallel gravity with the generalized MIT bag model are investigated. By incorporating the modified field equations, the influence of the generalized bag constant on the structure and physical characteristics of quark stars and neutron ...
