【摘要】：在冷暗物質(zhì)暈等級(jí)成團(tuán)宇宙學(xué)模型中,伴隨著暗物質(zhì)暈并合,星系中心黑洞也斷地并合和增長(zhǎng).于展Press-Schechter公式(EPS)我們編寫(xiě)了一自適應(yīng)時(shí)間長(zhǎng)Monte Carlo程序,重構(gòu)了表征暗物質(zhì)暈等級(jí)成團(tuán)并合樹(shù).在成功地建立了黑洞和暗物質(zhì)暈宇宙學(xué)演化模型后,我們通過(guò)引入直接吸積(包標(biāo)準(zhǔn)薄盤吸積和磁流體力學(xué)吸積)和隨吸積兩類黑洞吸積模式,論了黑洞自旋和質(zhì)量宇宙學(xué)演化.通過(guò)與觀測(cè)到AGN光度函數(shù)比較,我們發(fā)現(xiàn)黑洞通過(guò)磁流體力學(xué)吸積模式增長(zhǎng),與觀測(cè)符合最好.于以上理論框架,我們還研究了雙大質(zhì)量黑洞演化,發(fā)現(xiàn)雙黑洞通過(guò)共轉(zhuǎn)氣體吸積盤吸積對(duì)雙黑洞質(zhì)量比分存在顯著影響.
[Abstract]:In the cluster cosmological model of cold dark matter halo, with the combination of dark matter halo, the central black hole of a galaxy is also broken off to merge and grow. Based on the Press-Schechter formula (EPS), we have written an adaptive long time Monte Carlo program to reconstruct the cluster union tree which represents the level of dark matter halo. After successfully establishing the cosmological evolution model of black hole and dark matter halo, we introduce two kinds of black hole accretion models: direct accretion (including standard thin disk accretion and magnetohydrodynamic accretion) and accretion with accretion. The spin of black hole and the evolution of mass cosmology are discussed. Compared with the observed AGN photometric function, we find that the black hole grows through the magnetohydrodynamic accretion model, which is in good agreement with the observation. Based on the above theoretical framework, we also study the evolution of double-mass black holes. It is found that the mass score of double black holes is significantly affected by accretion of two black holes through a corotating gas accretion disk.
