A Log-Quadratic Relation Between the Nuclear Black-Hole Masses and Velocity Dispersions of Galaxies
We demonstrate that a log-linear relation does not provide an adequate description of the correlation between the masses of Super-Massive Black-Holes (SMBH, Mbh) and the velocity dispersions of their host spheroid (σ). An unknown relation between logMbh and log σ may be expanded to second order to obtain a log-quadratic relation of the form log (Mbh) = α+β log (σ/200kms )+β2[log (σ/200kms )]2. ...
متن کاملQuasar Black Hole Masses from Velocity Dispersions
Much progress has been made in measuring black hole (BH) masses in (non-active) galactic nuclei using the tight correlation between stellar velocity dispersions σ in galaxies and the mass of their central BH. The use of this correlation in quasars, however, is hampered by the difficulty in measuring sigma in host galaxies that tend to be overpowered by their very bright nuclei. We discuss resul...
متن کاملA log-quadratic relation for predicting supermassive black hole masses from the host bulge Sérsic index
We reinvestigate the correlation between black hole mass and bulge concentration. With an increased galaxy sample (totalling 27), updated estimates of galaxy distances, black hole masses, and Sérsic indices n — a measure of concentration — we perform a least-squares regression analysis to obtain a relation suitable for the purpose of predicting black hole masses in other galaxies. In addition t...
متن کاملBlack hole masses in active galaxies
This contribution reviews two topics of current interest in the study of black hole demographics in active galaxies: Can the stellar velocity dispersions of quasar host galaxies be measured? And can we constrain the black hole mass function below 10 M ?
متن کاملthe relation between bilingualism and translation: a case study of turkish bilingual and persian monolingual translation students
translation studies have become an accepted academic subject and books, journals and doctoral dissertations appear faster than one can read them all (bassnet and lefevere, 1990). but this field also brought with itself so many other issues which needed to be investigated more, in the heart of which, issues like ideology, ethics, culture, bilingualism and multilingualism. it is reported that ove...
