Evolution of supermassive black holes
Supermassive black holes (SMBHs) are nowadays believed to reside in most local galaxies, and the available data show an empirical correlation between bulge luminosity or stellar velocity dispersion and black hole mass, suggesting a single mechanism for assembling black holes and forming spheroids in galaxy halos. The evidence is therefore in favour of a co-evolution between galaxies, black hole...
متن کاملGrowth of supermassive black holes and metallicity in quasars
The strong correlation between the mass of the central supermassive black hole (SMBH) and the bulge in some galaxies and quasars implies that the formation of the black hole is somehow linked to the bulge. The measurement of metallicity by NV/CIV or NV/HeII in quasars allows to discuss a possible way of formation of the black hole. In this Letter we trace the metallicity along the possible rout...
متن کاملFormation and Evolution of Supermassive Black Holes
The correlation between the mass of supermassive black holes in galaxy nuclei and the mass of the galaxy spheroids or bulges (or more precisely their central velocity dispersion), suggests a common formation scenario for galaxies and their central black holes. The growth of bulges and black holes can commonly proceed through external gas accretion or hierarchical mergers, and are both related t...
متن کاملStudy of Outflows from Supermassive Black Holes
Our recent Chandra, XMM-Newton and Suzaku observations of several high redshift quasars have revealed the presence of massive outflows of highly ionized, high-metallicity material driven from near the black hole (a few gravitational radii, rg) with velocities of up to 0.7c (see Figure 1; Chartas et al. 2002, ApJ, 579, 169; Chartas et al. 2003 ApJ, 595, 85; Chartas et al. 2007, AJ, 133, 1849; Sa...
متن کاملSupermassive black holes
1 OF ALL the legacies of Einstein’s general theory of relativity, none is more fascinating than black holes. While we now almost take their existence for granted, for much of the 20th century black holes were viewed as mathematical curiosities with no counterparts in nature. Einstein himself never believed in black holes and wrote two papers in which he argued against their existence. Einstein’...
