Abstract

Over the past decade we have learned that probably all ellipticals and bulges of galaxies contain central supermassive black holes (SMBH). SMBH masses correlate well with the luminosities, and in turn the stellar masses of the bulges harboring them, with about 0.15% of the bulge mass being found in the SMBH. Pure disk galaxies, on the other hand, do not, in general, seem to contain SMBHs. Here we review the best cases for SMBH detection in galaxies, discuss methods and associated uncertainties, summarize correlations between SMBH masses and host galaxy properties, and finally address possible future developments.

Résumé

Durant la dernière décennie, nous avons appris que probablement toutes les galaxies elliptiques et les bulbes contiennent un trou noir central très massif (SMBH). Les masses des SMBH se corrèlent très bien avec les luminosités, et donc avec les masses, des bulbes dont ils sont les hôtes. Ils représentent environ 0.15% de la masse du bulbe. A lʼinverse, les galaxies disques ne semblent pas contenir de SMBH. Nous résumons ici les meilleurs cas de mise en évidence de SMBH dans les galaxies. Nous discutons ensuite des méthodes et de leurs incertitudes, des correlations entre les masses des SMBH et les propriétés de leurs galaxies hôtes et, enfin, des développements futurs possibles. Pour citer cet article : R. Bender, R.P. Saglia, C. R. Physique 8 (2007).
