This book was originally published in 2004. Black holes are among the most mysterious objects in the Universe. Weighing up to several billion Suns, massive black holes have long been suspected to be the central powerhouses of energetic phenomena such as quasars. Advances in astronomy have not only provided spectacular proof of this long-standing paradigm, but have revealed the unexpected result that far from being rare, exotic beasts, they inhabit the center of virtually all large galaxies. Candidate black holes have been identified in increasingly large numbers of galaxies, both inactive and active, to the point where statistical studies are possible. Fresh work has highlighted the close connection between the formation, growth, and evolution of supermassive black holes and their host galaxies. This volume contains the invited lectures from an international symposium that was held to explore this exciting theme, and is a valuable review for professional astronomers and graduate students.

Within the framework of coevolution between the central black hole and the host spheriod galaxy, the black hole growth has been investigated, the associated luminosity function of active galactic nuclei at different redshift has been calculated. Compared with the results of all kinds of deep survey observations, the semi-analytic results provide the fully explanation for the downsizing features. On the other hand, star formation processes, dust absorption and ohther stellar population properties in the primeval galaxies at high redshift, make the tight constraints on the research of cosmic reionization.

Download Measuring the Angular Momentum of Supermassive Black Holes Book in PDF, ePub and Kindle
Measuring the spin distribution of supermassive black holes is of critical importance for understanding how these black holes and their host galaxies form and evolve over time, yet this type of study is only in its infancy. This brief describes how astronomers measure spin in supermassive black holes using X-ray spectroscopy. It also reviews the constraints that have been placed on the spin distribution in local, bright active galaxies over the past six years, and the cosmological implications of these constraints. Finally, it summarizes the open questions that remain in this exciting new field of research and points toward future discoveries soon to be made by the next generation of space-based observatories.

Download The Interplay Between Supermassive Black Holes and Their Host Galaxies Book in PDF, ePub and Kindle
Supermassive black holes reside in the hearts of almost all massive galaxies. Their evolutionary path seems to be strongly linked to the evolution of their host galaxies, as implied by several empirical relations between the black hole mass (M BH) and different host galaxy properties. The physical driver of this co-evolution is, however, still not understood. More mass measurements over homogeneous samples and a detailed understanding of systematic uncertainties are required to fathom the origin of the scaling relations. In this thesis, I present the mass estimations of supermassive black holes in the nuclei of one late-type and thirteen early-type galaxies. Our SMASHING sample extends from the intermediate to the massive galaxy mass regime and was selected to fill in gaps in number of galaxies along the scaling relations. All galaxies were observed at high spatial resolution, making use of the adaptive-optics mode of integral field unit (IFU) instruments on state-of-the-art telescopes (SINFONI, NIFS, MUSE). I extracted the ...

The ultimate proofs that black holes exist have been obtained very recently thanks to the detection of gravitational waves from their coalescence and due to material orbiting at a distance of some gravitational radii imaged by optical interferometry or X-ray reverberation mapping. This book provides three comprehensive and up-to-date reviews covering the gravitational wave breakthrough, our understanding of accretion and feedback in supermassive black holes and the relevance of black holes for the Universe since the Big Bang. Neil J. Cornish presents gravitational wave emission from black hole mergers and the physics of detection. Andrew King reviews the physics of accretion on to supermassive black holes and their feedback on host galaxies. Tiziana Di Matteo addresses our understanding of black hole formation at cosmic dawn, the emergence of the first quasars, black hole merging and structure formation. The topics covered by the 48th Saas-Fee Course provide a broad overview of the importance of black holes in modern astrophysics.

Download Supermassive Black Holes in the Distant Universe Book in PDF, ePub and Kindle
Quasars, and the menagerie of other galaxies with "unusual nuclei", now collectively known as Active Galactic Nuclei or AGN, have, in one form or another, sparked the interest of astronomers for over 60 years. The only known mechanism that can explain the staggering amounts of energy emitted by the innermost regions of these systems is gravitational energy release by matter falling towards a supermassive black hole --- a black hole whose mass is millions to billions of times the mass of our Sun. AGN emit radiation at all wavelengths. X-rays originating at a distance of a few times the event horizon of the black hole are the emissions closest to the black hole that we can detect; thus, X-rays directly reveal the presence of active supermassive black holes. Oftentimes, however, the supermassive black holes that lie at the centers of AGN are cocooned in gas and dust that absorb the emitted low energy X-rays and the optical and ultraviolet light, hiding the black hole from view at these wavelengths. Until recently, this low-energy absorption presented a major obstacle in observational efforts to map the accretion history of the universe. In 1999 and 2000, the launches of the Chandra and XMM-Newton X-ray Observatories finally broke the impasse. The impact of these observatories on X-ray astronomy is similar to the impact that the Hubble Space Telescope had on optical astronomy. The astounding new data from these observatories have enabled astronomers to make enormous advances in their understanding of when accretion occurs.

Download Unveiling Supermassive Black Hole Growth and Co-Evolution Using X-rays Book in PDF, ePub and Kindle
Supermassive black holes (SMBHs) are thought to co-evolve alongside their host galaxiesboth through mergers with other SMBHs, and through accretion and the active galactic nucleus (AGN) emission it powers. Binary SMBHs are a step along the way to SMBH mergers, and so are important for understanding SMBH-galaxy co-evolution. Understanding the activity period of AGN (the AGN duty cycle) is also important for understanding how much of an impact AGN can have on their host galaxies. It is for these reasons in my thesis that I studied binary SMBHs and the AGN duty cycle. In my thesis I investigated whether candidate binary SMBHs had distinct spectra from single SMBHs, a phenomenon predicted by many theoretical models. I found that they do not, which could mean that the theoretical models are incorrect, or that the candidates were not truly binary SMBHs. This null result motivates additional theory development as well as future observational campaigns to find or confirm binary SMBHs. I also searched for recently deactivated AGN in a sample of obscured AGN, to see if that could shed light on the time periods over which AGN turn off and on. I found one AGN that deactivated no more than 87-220 years ago, indicating that perhaps AGN flicker on timescales of decades and centuries.
