Time evolution of the ionization state of metals in the cosmic baryons is investigated in a cosmological context without the assumption of ionization equilibrium. We find that a significant fraction of ionized oxygen (Ovii and Oviii) in the warm-hot intergalactic medium (WHIM) is not in the ionization equilibrium state at a redshift of z≃ 0. We also investigate the effect on the detectability a...

Supernova remnants interacting with molecular clouds are potentially exciting systems in which to detect evidence of cosmic ray acceleration. Prominent γ-ray emission is produced via the decay of neutral pions when cosmic rays encounter the nearby dense clouds. In many of the supernova remnants coincident with γ-ray sources, the presence of OH(1720 MHz) masers is used to identify interaction wi...

We present the results of linear analysis and two-dimensional local magnetohydrodynamic (MHD) simulations of the Parker instability, including the effects of cosmic rays (CRs), in magnetized gas disks (galactic disks). As an unperturbed state for both the linear analysis and the MHD simulations, we adopted an equilibrium model of a magnetized two-temperature layered disk with constant gravitati...

Tracking the transmutation of the angular component of a complex Higgs field into the longitudinal polarisation state of the gauge field during the termination of inflation in hybrid models might reveal interesting details of the real time Higgs effect and of the electroweak dynamics . The excitation rate of the different polarisation states might be different as well as the thermal relaxation ...

A possible candidate for the present accelerated expansion of the Universe is “phantom energy”, which possesses an equation of state of the form ω ≡ p/ρ < −1, consequently violating the null energy condition. As this is the fundamental ingredient to sustain traversable wormholes, this cosmic fluid presents us with a natural scenario for the existence of these exotic geometries. In this context,...

Evidence is presented for neutrons emanating from partially deuterated titanium foils (TiDx) subjected to non-equilibrium conditions (charged particle results appear in a separate paper in this proceedings). Two types of deuteriding and varied currents were employed to produce the non-equilibrium conditions within the foils, and emissions lasted over long durations. Experiments were conducted i...

We consider the stimulated emission of gravitons from an initial state of thermal equilibrium, under the action of the cosmic gravitational background eld. We nd that the low-energy graviton spectrum is enhanced if compared with spontaneous creation from the vacuum; as a consequence, the scale of innation must be lowered, in order not to exceed the observed CMB quadrupole anisotropy. This eeect...

Recently, Barrow proposed a modified area-entropy relation S=(A/A0)1+Δ/2, where the exponent Δ, ranges 0≤Δ≤1, by taking account of quantum gravitational deformation effects to black hole’s surface. In recent literature, this horizon entropy has been adopted cosmological context. Following this, we obtained law emergence, which describes dynamics universe, with in context equilibrium thermodynam...
