In this article we treat the non-adiabatic photon-to-axion resonant conversion of curvature radiation, synchrotron emission and inverse Compton scattering dominating spectral density function pulsars. First, introduce models benchmark observational data.vWe adopt a state-of-the-art profile that relieves tension with quantum electrodynamics vacuum polarization effect in highly magnetic stars, le...

We present the energy-dependent power spectral density (PSD) and cross-spectral properties of Mkn 766, obtained from combining data obtained during an XMM-Newton observation spanning six revolutions in 2005 with data obtained from an XMM-Newton long-look in 2001. The PSD shapes and rms-flux relations are found to be consistent between the 2001 and 2005 observations, suggesting the 2005 observat...

We have carried out a radio-wavelength imaging survey of 45 bright-rimmed clouds (BRCs), using the Australia Telescope Compact Array to characterise the physical properties in their ionised boundary layers. We detected radio emission from a total of 25 clouds and using a combination of Digitised Sky Survey and mid-infrared MSX 8 μm images classified the emission into that associated with the io...

To evaluate daytime and nighttime carbon balance and assimilate export in soybean (Glycine max [L.] Merrill) leaves at different photon flux densities, rates of CO(2) exchange, specific leaf weights, and concentrations of sucrose and starch were measured at intervals in leaves of pod-bearing ;Amsoy 71' and ;Wells II' plants grown in a controlled environment room. Assimilate export was estimated...

Crystal decay should then be proportional to strictly proportional to accumulated dose at the highcumulative dose, up to fluxes at which heating rates or flux density of beams from undulators at third-generarelated phenomena are too great to control.

The availability of new high-energy synchrotron radiation sources, such as the Advanced Photon Source (APS), have made measurements of the spin-dependent momentum distribution of electrons much easier. Making these experiments feasible, however, requires high-energy x-rays (E > 30 keV) with not only a high flux density but also a high degree of circular polarization. Circularly polarized (CP) x...

An elementary kinematic model for emission produced by relativistic spherical colliding shells is studied. The case of a uniform blast-wave shell with jet opening angle θj ≫ 1/Γ is considered, where Γ is the Lorentz factor of the emitting shell. The shell, with comoving width ∆r, is assumed to be illuminated for a comoving time ∆t and to radiate a broken power-law νLν spectrum peaking at comovi...
