Their demographics lead to the following conclusions:(1) BH mass is consistent with predictions based on quasar energetics.(2) BH mass correlates with the luminosity of the \bulge" but not the diskcomponent of the host galaxy.(3) BH mass correlates with the luminosity of the high{density central com-ponent in disk galaxies independent of whether this is a real bulge (a mini{elliptical)or a \pseudobulge" (believed to form via inward transport of disk material).(4) BH results increasingly support the hypothesis that the major event thatforms a giant elliptical and the main AGN phase of the BH are the same event.Issues that need further work include:(i) BH masses from reverberation mapping are a factor of 5 smaller thanthose from detailed dynamical studies. Contributing factors are identied thatsuggest that this discrepancy may not be fundamental.(ii) Do any bulges or ellipticals lack BHs? Are there BHs in pure disk galaxies?(iii) We need to know whether some of the mass detected in dynamical studiesis in dark clusters of objects and not in BHs. 2001 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57101020 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Vol.10 |
