Download or read book The Study of Galaxy Formation and the Development of MOSFIRE written by Kristin Rose Kulas and published by . This book was released on 2013 with total page 157 pages. 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.

This book was released on 2004-08-03 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2007-05-02 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: John Dyson has contributed to the study of the hydrodynamic processes that govern a wide variety of astrophysical sources which he has helped explain. In this volume dedicated to him, introductory reviews to a number of the key processes and to the sources themselves are given by leading experts. The book provides a coherent introduction to the astrophysics of diffuse sources suitable for postgraduate students and researchers in astrophysics.
