Available in PDF, EPUB and Kindle. Book excerpt: Advanced technologies in astronomy at various wavelengths have provided us with high resolution and high quality data on the QSO population. This meeting was aimed at understanding the morphology and nature of the host galaxies and environments of QSOs. The invited lectures as well as the contributed and poster papers highlighted the main issues of current research: the stellar and gaseous content of the underlying galaxy; the characterization of the population of companions and the nature of their interaction with the host galaxy; the connection between radio-loud QSO and radio-galaxies, and QSOs and ULIRGs; the evolution with redshift of both the host galaxy and its environment, and the main implications in theories of galaxy formation and evolution. This volume provides a valuable overview and timely update of the exciting and rapidly developing field of QSO hosts and their environments - essential reading for graduate students and researchers.

Available in PDF, EPUB and Kindle. Book excerpt: Stellar population synthesis (SPS) models are key to interpreting the spectral energy distributions of galaxies. While different models typically agree at optic wavelengths, these same models give vastly different predictions in the near-infrared, mainly due to different treatments of late-stage stellar evolution, in particular the Thermally Pulsing Asymptitic Giant Branch (TP-AGB) phase. This thesis tests three popular SPS models, with a focus on evaluating the different treatments of this phase.
Download or read book An Introduction to Active Galactic Nuclei written by Bradley M. Peterson and published by Cambridge University Press. This book was released on 1997-02-13 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: How can we test if a supermassive black hole lies at the heart of every active galactic nucleus? What are LINERS, BL Lacs, N galaxies, broad-line radio galaxies and radio-quiet quasars and how do they compare? This timely textbook answers these questions in a clear, comprehensive and self-contained introduction to active galactic nuclei - for graduate students in astronomy and physics. The study of AGN is one of the most dynamic areas of contemporary astronomy, involving one fifth of all research astronomers. This textbook provides a systematic review of the observed properties of AGN across the entire electromagnetic spectrum, examines the underlying physics, and shows how the brightest AGN, quasars, can be used to probe the farthest reaches of the Universe. This book serves as both an entry point to the research literature and as a valuable reference for researchers in the field.

This book was released on 2019 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Observations reveal that supermassive black holes (SMBHs) grow through the accretion of gas at the centers of galaxies as luminous active galactic nuclei (AGN), releasing radiation that drives powerful outflows of ionized and molecular gas. These winds are thought to play a critical role in galaxy evolution by regulating star formation and the growth of galaxies and their SMBHs. To test this model, we must quantify the dynamic impact of outflows by measuring their mass outflow rates and energetics. Using spatially resolved spectroscopy and imaging from the Hubble Space Telescope and Cloudy photoionization models we mapped the ionized gas kinematics and mass distributions of narrow line region (NLR) outflows in nearby active galaxies. We find that the outflows contain up to several million solar masses of ionized gas and are limited to distances of 1 - 2 kiloparsecs from the nucleus. The maximum mass outflow rates are M = 3 - 12 solar masses per year and the outflow gas mass, velocity, radial extent, and energetics are positively correlated with AGN luminosity. We use our results to test simplified techniques with less stringent data requirements and find that they significantly overestimate the gas mass. These results are crucial for modeling powerful outflows at higher redshift that may considerably influence star formation rates and the formation of galactic structure.

Available in PDF, EPUB and Kindle. Book excerpt: The epoch of z~2-3 is a noticeably more active time in our universe for galaxies, with the global star-formation rate density at its peak. Galaxies during this era are experiencing many internal and external processes such as large-scale outflows from star formation or active galactic nuclei (AGN) activity, inflows from cool gas, and mergers, which can alter the properties (e.g., structure, metallicity, star-formation rate, velocity dispersion) and evolution of galaxies. This elevated level of activity makes z~2-3 objects ideal for examining galaxy formation. In the rest-frame optical many important diagnostic lines exist that allow one to study galaxy properties, including the Balmer series, [O III][lambda][lambda] and [N II][lambda]. For galaxies at z~2-3, however, these lines will become very faint and shift into the near- infrared wavelength regime. As a consequence of this, near-infrared spectroscopy on a large telescope plays an integral role in studying high-redshift galaxies. For my thesis I have used near-infrared spectroscopy, acquired at the Keck Observatory, to study in depth how gas supplies are regulated during the formation of galaxies. Simultaneously, I have also worked to bring to realization one of the most advanced near-IR spectrographs for the astronomical community through my instrumentation research on MOSFIRE, the Multi-Object Spectrometer For Infrared Exploration.
