Development of computational framework for optimizing broadband x-ray multilayer coatings for high-energy astrophysics

Optics + Optoelectronics
The design of broadband, high-angular-resolution X-ray optics is pivotal for advancing astronomical instrumentation, particularly in missions targeting high-energy astrophysical phenomena across the 2–200 keV range. Depth-graded multilayer (DGM) coatings

Oscillations of hypothetical strange stars as an efficient source ultra-high-energy particles.

Proceedings of 7th International Symposium on Ultra High Energy Cosmic Rays — PoS(UHECR2024)
We investigate the dynamical behavior of strange quark matter (SQM) objects, such as stars and planets, when subjected to radial oscillations induced by tidal interactions in stellar systems.

Lensing effects of ultra-high-energy cosmic rays propagating in the Galactic magnetic field

International Conference on Rebooting Computing
Since ultra-high-energy cosmic rays (UHECRs) are electrically charged particles, they are deflected by magnetic fields. Those magnetic fields can act as lenses, altering their trajectories and (de)magnifying their apparent source images.
