The topic of cosmic strings provides a bridge between the physics of the very small and the
very large. They are predicted by some unified theories of particle interactions. If they exist …

▪ Abstract The central half kiloparsec region of our Galaxy harbors a variety of phenomena
unique to the central environment. This review discusses the observed structure and activity …

We investigate the constraints that can be placed on the cosmic string tension by using the
current pulsar timing array (PTA) limits on the gravitational wave background. We have …

In this report we review the important progress made in recent years towards understanding
the experimental data on ultra-high-energy (E≳ 1 0 9 GeV) cosmic rays. We begin with a …

This paper reviews the physical state of stars and Interstellar Matter in the Galactic Bulge
(radius R∼0.3-3\, kpc from the dynamical center of the Galaxy), in the Nuclear Bulge …

The scientific literature is rich with studies of non-standard primodial nucleosynthesis. We
review a number of these variants on the simplest standard big bang (SBB) nucleosynthesis …

Magnetic fields are an essential constituent of our Universe and their manifestations on
Earth were recognized a long time ago: from loadstones found in the ancient Greece in the …

This current updated and expanded text reflects the large number of scientific advances,
both theoretically and experimentally, within the discipline of cosmoparticle physics in the …

The effect of charge on a vortex world-sheet is examined. The relationship between world-
sheet charge, winding number, and the flow of momentum along the vortex is illuminated …

The observation of quasars at high redshifts presents a mystery in the theory of black hole
formation. In order to source such objects, one often relies on the presence of heavy seeds () …
