The X-ray Background (Deep Fields, Luminosity Functions and Type-Ⅱ Quasars)

引用

天文研究与技术 2003年第S1期 136-146页

作者： günther Hasinger Max Planck Institut für extraterrestrische PhysikPostfach 1319 D-84541 Garching Germany

Deep X ray surveys have shown that the cosmic X ray background (XRB) is largely due to the accretion onto supermassive black holes, integrated over the cosmic time. These surveys have resolved more than 80% of the 0.1-10keV X ray background into discrete sources. Optical spectroscopic identifications show that the sources producing the bulk of the X ray background are a mixture of obscured (type 1) and unobscured (type 2) AgNs, as predicted by the XRB population synthesis models. A class of highly luminous type 2 AgN, so called QSO 2s, has been detected in the deepest Chandra and XMM Newton surveys. The new Chandra AgN redshift distribution peaks at much lower redshifts (z≈0.7) than that based on ROSAT data, indicating that Seyfert galaxies peak at significantly lower redshifts than QSOs.

Spatial and temporal dynamics of Pai forest vegetation in Pakistan assessed by RS and gIS

Journal of Forestry Research 2017年第3期28卷 593-603页

作者： A.A.Siyal A.g.Siyal R.B.Mahar U.S.-Pakistan Center for Advanced Studies in Water(USPCAS-W) Mehran University of Engineering and TechnologyJamshoroPakistan Department of Land and Water Management Sindh Agriculture UniversityTandojamPakistan

Pai, an arid forest in Sindh Province of Pakistan, is important for the environmental, social, economic development and conservation of ecosystems of the province. Considering the significance of the forest for Sindh and the calls from the local population for its deforestation, we quantified the spatial and temporal variation in the vegetation of the forest and land surface temperature （LST） using optical and thermal Landsat satellite data. Our analysis of temporal （1987-2014） images with ArcgIS 10.1 revealed that the dense forest area was greatest at 725 ha （37 % of the total forest area） during 2013 while it was smallest at 217 ha （11%） in 1992. The sparse forest area peaked during 1987 at 1115 ha （58 %） under shrubs whereas it was smallest at 840 ha （43 %） in 1992, and the maximum deforestation of Pai forest occurred during 1992. Spatial change in vegetation over a period of about 27 years （1987-2014） revealed that vegetation increased on an area of 735 ha （37 %）, decreased on 427 ha （22 %）, and there was no change on 808 ha （41%） of the forest. Variation in temperature between shaded （dense forest） and unshaded areas （bare land） of the forest was from 6 to 10 ℃. While the temperature difference between areas with sparse forest and bare land ranged from 4 to 6℃. An inverse relationship between LST and NDVI of Pai forest with coefficients of determination of 0.944 and 0.917 was observed when NDVI was plotted against minimum and maximum LST, respectively. The vegetation in the forest increased with time and the areas of more dense Pai forest supported lower surface temperature and thus air temperature.
