We investigate photon emission at the hadronization stage from a quark-gluon plasma created in relativistic heavy-ion collisions. A recombination-model picture suggests that quark and an antiquark bind into meson state hadronization, which would apparently violate energy conservation if there is nothing else involved. consider here process where recombination accompanies emission. This analog o...

This comparative study inspects the MHD three-dimensional revolving flow and temperature transmission of a radiative stretching surface. The nanofluid is modeled using Tiwari Das model. Water base fluid, nanoparticles are composed two different types nanoparticle, i.e., gold silver (Au Ag). non-radiative heat notion examined in field that results nonlinear energy equation. Conformist transforma...

Predictions of temperature and precipitation responses to changes in the anthropogenic emissions of climate forcers require the quantification of the radiative forcing exerted by those changes. This task is particularly difficult for near-term climate forcers like aerosols, methane, and ozone precursors because their short atmospheric lifetimes cause regionally and temporally inhomogeneous radi...

We have used the SAURON panoramic integral field spectrograph to study the structure of the Ly-α emission-line halo, LAB1, surrounding the sub-millimeter galaxy SMM J221726+0013. This emission-line halo was discovered during a narrow-band imaging survey of the z = 3.1 large-scale structure in the SSA22 region. Our observations trace the emission halo out to almost 100 kpc from the sub-millimete...

We measured in thermal emission the 63-Jlm line due to thermospheric atomic oxygen Oep), using a far-infrared spectrometer on a balloon platform at 37 km altitude over Palestine, Texas (32°N), on June 20, 1983. From measurements of the equivalent width of this line at two elevation angles, we find a weak angular dependence: the equivalent width increases by a factor of 1.5 :t 0.3 as the angle d...

The current study focuses on the natural-convection flow of nanofluids with boundary layer over a circular cylinder uniform thermal wall varying magnetic force from 0 to 1.5, radiative effects 1, heat generation and Joule heating 1. problem is represented in form partial differential equations. dimensional equations converted into dimensionless help suitable stream functions. Then, resultant ar...

In this paper, a K-band ground-based hyperspectral microwave radiometer for atmospheric sounding is proposed, which improves the profile error and vertical resolution of moisture profiling under the high water vapor condition. The hyperspectral microwave radiometer (80 K-band spectral channels) can observe the rapidly changing weather with high sensitivity and accuracy of brightness temperature...

The annihilation of neutralino dark matter in the Galactic Center (GC) may result in radio signals that can be used to detect or constrain the dark matter halo density profile or dark matter particle properties. At the Galactic Center, the accretion flow onto the central Black Hole (BH) sustains strong magnetic fields that can induce synchrotron emission by electrons and positrons generated in ...

A rather large computational effort is required for calculating the exact values of the spectral radiative extinction, absorption and scattering coefficients in pulverized coal combustors, which contain a polydispersed solid-gas mixture of reactants and combustion products (coal, char, fly ash and soot particles and gaseous components). This computation becomes an especially significant problem...
