The legacy and large-scale distribution of active galaxies
Philosophical Transactions of the Royal Society A Mathematical Physical and Engineering Sciences 363:1828 (2005) 613-619
Abstract:
If accretion onto massive black holes is the power source for active galaxies, then nearby galaxies should contain 'dead quasars': black holes that do not shine, either because they are starved for fuel or because they accrete with low radiative efficiency. This article briefly reviews the evidence that most inactive galaxies contain black holes at their centres, and how the local distribution of black holes is related to the population of active galaxies. 漏 2005 The Royal Society.Black holes, cuspy atmospheres and galaxy formation

Supermassive black hole mass measurements for NGC 1300 and NGC 2748 based on HST emission-line gas kinematics
ArXiv astro-ph/0502573 (2005)
Abstract:
We present Space Telescope Imaging Spectrograph emission-line spectra of the central regions of the spiral galaxies NGC 1300 and NGC 2748. From the derived kinematics of the nuclear gas we have found evidence for central supermassive black holes in both galaxies. The estimated mass of the black hole in NGC 1300 is 6.6 (+6.3, -3.2) x 10^7 solar masses and in NGC 2748 is 4.4 (+3.5, -3.6) x 10^7 solar masses (both at the 95% confidence level). These two black hole mass estimates contribute to the poorly sampled low-mass end of the nuclear black hole mass spectrum.Commission 28: Galaxies
