Spatial energy spectrum of primordial magnetic fields
Grazyna Siemieniec-Ozieblo
Here, we analyze the primordial magnetic field transition between a radiative and a matter-dominated universe. The gravitational structure formation affects its evolution and energ…
A study of diffusive shock acceleration as a process explaining observations of 1 E0657-56 galaxy cluster
G. Siemieniec-Ozieblo
Chandra X-ray observations of the 1 E0657-56 galaxy cluster diffuse emission reveal the existence of large scale cluster merger shock. We study the observed radio and X-ray data of…
Magnetized cosmic walls
G. Siemieniec-Ozieblo, A. Woszczyna
Nonlinear growth of one-dimensional density structures with a frozen-in magnetic field is investigated in Newtonian cosmology. A mechanism of magnetic field amplification is discus…
On energy spectra of UHE cosmic rays accelerated in supergalactic accretion flows
G. Siemieniec, M. Ostrowski
Some ultra-high energy (UHE) cosmic ray (CR) events may be correlated with the Local Supercluster plane. We consider acceleration of such particles at the large-scale accretion flo…
