Our research examines various characteristics of neutron stars, pulsars, X-ray binaries, and supernova remnants to address core questions regarding compact object physics, cosmic-ray generation and movement in our galaxy, particle acceleration processes, accretion dynamics, and the overall population of Galactic X-ray sources (encompassing neutron stars, black holes, X-ray binaries, and micro-quasars).
Neutron stars represent the collapsed cores of massive stars, with surfaces so intensely hot they radiate ultraviolet and X-ray energy. Younger neutron stars featuring active, particle-filled magnetospheres appear as pulsars - celestial bodies emitting powerful, periodic bursts of radio waves, X-rays, or visible light. The extraordinary conditions within neutron stars make them ideal natural laboratories for investigating the poorly understood behavior of ultra-dense, highly magnetized, superconducting matter. These extreme states cannot be replicated in terrestrial laboratories, making neutron star observation the sole method for studying nuclear reactions and elementary particle interactions under such conditions. These findings hold crucial significance for particle physics and quantum field theory. Analyzing pulsar winds helps decipher complex PWN structures, reveals the behavior of relativistic magnetized outflows and their interaction with surrounding matter, and demonstrates remarkably efficient particle acceleration (reaching PeV energy levels) in these outflows. These physical mechanisms also apply to numerous other astrophysical phenomena, including AGN and micro-quasar jets.
