Using DIRBE and FIRAS maps at high latitude (|b| > 10) we derive the spatial distribution of the dust temperature associated with the diffuse cirrus and the dense molecular clouds. For a ν emissivity law, we find that the equilibrium dust temperature of the cirrus is about 17.5 K with only small variations over the high latitude sky. Comparison of the far Infrared DIRBE maps shows the presence ...

this study attempts to review and analyze abu-firas's roomiia ode and identify the elements composing it by going through the text rhetorically and semantically. in this research the special quality of the ode has affected the selection of the method and coming to a result. in this paper, the authors have taken advantage of the method called discourse analysis of poem, the effective technique t...

This paper tackles the cultural patterns in Abu Firas Hamdani's captivity poetry, namely Ra’iyyah poem. The poet, who is normally a part of ideological, cultural, or social paradigms, represents and regenerates, consciously unconsciously, patterns, especially those represented by his predecessors their literary works, whether prose verse. Antonyms displacement, many other linguistic tools, allo...

We present predicted full-sky maps of submillimeter and microwave emission from the diffuse interstellar dust in the Galaxy. These maps are extrapolated from the 100μm emission and 100/240μm flux ratio maps that Schlegel, Finkbeiner, & Davis (1998; SFD98) generated from IRAS and COBE/DIRBE data. Results are presented for a number of physically plausible emissivity models. The correlation of COB...

tradition has primary importance in modern arabic poetry, and invoking traditional elements is a remarkably invaluable poetic source. tradition has many resources among which literary tradition is a rich storehouseon whichpoets deeply rely. literary tradition contains many elements among which poetic figures are probably the most influential and inspirational. this article attempts to study the...

Studies of the far-IR extragalactic background (FIRB) provide information on the star formation history of the universe complementary to that given by optical observations. The upper limits on the FIRB intensity resulting from recent analyses of COBE/FIRAS data entail interesting constraints on the possibility that most of the star formation activity occurring during early phases of galaxy evol...

We have reened the analysis of the data from the FIRAS (Far InfraRed Absolute Spectrophotometer) on board the COBE (COsmic Background Explorer). The FIRAS measures the diierence between the cosmic microwave background and a precise blackbody spectrum. We nd new tighter upper limits on general deviations from a blackbody spectrum. The RMS deviations are less than 50 parts per million of the peak...

We discuss the sources which are likely to dominate the ionizing field throughout the Local Group. In terms of the limiting flux to produce detectable Hα emission (∼ 4 − 10 × 10 phot cm s), the four dominant galaxies (M31, Galaxy, M33, LMC) have spheres of influence which occupy a small fraction (5− 10%) of the Local Volume. There are at least two possible sources of ionization whose influence ...

We analyse the implications of future observations of the CMB absolute temperature at centimeter and decimeter wavelengths, where both ground, balloon and space experiments are currently under study to complement the accurate COBE/FIRAS data available at λ < ∼ 1 cm. Our analysis shows that forthcoming ground and balloon measures will allow a better understanding of free-free distortions but wil...
