Title: | Gravitational redshift of emission lines in the AGN spectra | Authors: | Bon, Nataša Bon, Edi MARZIANI, Paola Jovanović, Predrag |
Issue Date: | 2015 | Journal: | ASTROPHYSICS AND SPACE SCIENCE | Number: | 360 | First Page: | 7 | Abstract: | The detection of gravitationally redshifted optical emission lines has been reported just for a few active galaxies. In this paper we give a short overview of studies that analyzed or exploited the detection of the gravitational redshift in optical AGN spectra. In addition, we tested the consistency of gravitational redshift as the physical origin of the redward shifts observed in their spectra using a sample of {≈}50 Hamburg-ESO intermediate to high redshift quasars that are among the most luminous quasars known (10^{47} ≲ L ≲ 10^{48} erg/s), and are expected to host very massive black holes. To this aim we modeled the line profile with accretion disk models around a black hole. <P /> | URI: | http://hdl.handle.net/20.500.12386/24202 | URL: | https://link.springer.com/article/10.1007%2Fs10509-015-2555-5 https://arxiv.org/pdf/1602.03688.pdf |
