Abstract In this contribution, we present the first numerical simulations of a relativistic outflow propagating through inner hundreds parsecs its host galaxy, including atomic and ionized hydrogen, cooling effects ionization. Our results are preliminary, but observe efficient shock ionization hydrogen in interstellar clouds. The mean density medium these initial is lower than that expected typ...

The focus of this work is on identifying the processes behind the sustained initiation of ionization, or "ignition", at the inlet of a self-field magnetoplasmadynamic thruster (MPDT). Plasma accelerators generate high Isp thrust via a combination of high power densities and low mass densities, resulting in strong gradients of temperature and density, particularly in the areas of current concent...

High energy irradiation to the hydrogen bonded system is important in relevance with the initial process of DNA and enzyme damages. In the present study, the effects of radiation to catalytic triad have been investigated by means of direct ab-initio molecular dynamics (AIMD) calculation. As a model of the catalytic triad, Ser-His-Glu residue, which is one of the important enzymes in the acylati...

Recently an increasing interest in the investigation of relativistic ionization phenomena has been observed [1–10]. Relativistic effects will appear if the electron velocity in the initial bound state or in the final state is comparable with the speed of light. The initial state should be considered relativistic in the case of inner shells of heavy atoms [3,4]. In a recent paper [10] the photoi...

A novel expansion of the Thomas-Fermi potential for a weakly ionized atom is presented. It is employed in calculating the ionization energies of neutral atoms as they are predicted by an extended version of the Thomas-Fermi model which includes the exchange energy and the leading quantum correction. The ionization energy, I, can be split into a smooth part, /stat, that is here obtained by the s...

The radiative effects by high-redshift ultraviolet radiation background (UVB) heats the gas in the IGM and eliminate the neutral hydrogen and helium that dominate the cooling of the primordial gas. We investigate the role of the radiative effects for the temporal evolution of the reionization fraction by using cosmological Smooth Particle Hydrodynamics (SPH) simulations. We find that the increa...

The analytical performance and a suggested mechanism for zero volt paper spray using chromatography paper are presented. A spray is generated by the action of the pneumatic force of the mass spectrometer (MS) vacuum at the inlet. Positive and negative ion signals are observed, and comparisons are made with standard kV paper spray (PS) ionization and nanoelectrospray ionization (nESI). While the...

Abstract Electrons in atoms and molecules can not respond immediately to the action of intense laser field. There is a time lag (about 100 attoseconds) between instants field maximum ionization-rate maximum. This characterizes response electronic wave function strong-field ionization event has important effects on dynamics ionized electron. For polar with large permanent dipole, direct measurem...

Intense-field ionization of the hydrogen molecular ion by linearly-polarized light is modelled by direct solution of the fixed-nuclei time-dependent Schrödinger equation and compared with recent experiments. Parallel transitions are calculated using algorithms which exploit massively parallel computers. We identify and calculate dynamic tunnelling ionization resonances that depend on laser wave...
