This book was released on 2005-05-23 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: The possibilities of astronomical observation have dramatically increased over the last decade. Major satellites, like the Hubble Space Telescope, Chandra and XMM Newton, are complemented by numerous large ground-based observatories, from 8m-10m optical telescopes to sub-mm and radio facilities. As a result, observational astronomy has access to virtually the whole electromagnetic spectrum of galaxies, even at high redshifts. Theoretical models of galaxy formation and cosmological evolution now face a serious challenge to match the plethora of observational data. In October 2003, over 170 astronomers from 15 countries met for a 4-day workshop to extensively illustrate and discuss all major observational projects and ongoing theoretical efforts to model galaxy formation and evolution. This volume contains the complete proceedings of this meeting and is therefore a unique and timely overview of the current state of research in this rapidly evolving field.

Available in PDF, EPUB and Kindle. Book excerpt: The unprecedented Herschel data have revolutionized our view of the IR universe, providing new insights to galaxy formation and evolution. However, the Herschel data are still far away from being fully explored, mainly due to three reasons. First, in most of the Herschel wide fields, we are still lacking ancillary data even in the optical/near-IR, which prevents us from doing any follow-up analysis. Second, even in the few fields that have sufficient ancillary data in various archives, there is no homogeneous reduction such that the data can be readily used. Third, but not the least, the long-standing problem of poor spatial resolution in FIR/sub-mm observations severely limits our capability of counterpart identification, and hence creates tremendous obstacles in obtaining redshifts, modeling the spectral energy distributions, deriving star formation rates, etc. In this thesis, I present our approach to attack these problems. My basic task is to establish a methodology that can be applied to all the Herschel wide-field survey data, with the science goal of constructing the largest, well-defined sample of highredshift Ultra-Luminous InfarRed Galaxies (ULIRGs) whose optical-to-far-IR SEDs are accurately measured. We first conduct a comprehensive search of the available archival optical data in the public domain. Moreover, we have been conducting our own deep optical survey, Mizzou WIYN Survey, to observe those fields that lack full range optical data coverage. To facilitate the data reduction process, I have developed APUS, a pipeline building and management tool that offers great repeatability, scalability, and maintainability. With this tool, we can reduce all these data in a uniform manner and create deep optical mosaics. To combat the problem of poor spatial resolution in the Herschel data, we have developed a source de-blending algorithm, which I have implemented as a software tool called CIDer. Using this tool, we can extract the major contributors to the FIR fluxes based on the position priors from the high-resolution optical data. Treating all the Herschel wide-field data is obviously beyond the scope of an individual thesis. Therefore, my thesis mainly focuses on one field, namely the "First Look Survey" field. As the first study case, we compiled and reduced the full-range multi-wavelength data in this field, and constructed the panchromatic SEDs from optical to FIR using CIDer. The redshifts of the sources were found to be ranging from z = 0 to ~ 3. We derived the total IR luminosities by fitting modified black body model or starbursting templates, which are found to be ranges from 3 x 10[superscript 10] to ~ 10[superscript 13] L[SYMBOL]_ after taking into account the cut to ensure reliability of the CIDer result. On the L[subscript IR]-T plane, the sources show the similar turning over behavior as in our previous study Yan & Ma (2016), implies a limited size of the dust star forming sites. Also presented in the thesis is our earlier work on the Herschel-detected SDSS quasars. The project was conducted before we have the CIDer to obtain the fullrange SEDs and thereby the redshifts. Instead, we aimed at the quasars, which we can measure the redshift spectroscopically and to a high redshift. In the project, it is found that the Herschel-detected quasars are mostly ULIRGs, and are forming stars very actively. This implies the co-evolution of extreme AGNs and star formation.

Available in PDF, EPUB and Kindle. Book excerpt: "These proceedings of the first meeting of the Subaru International Conference Series held in December 2007 in Hayama, Japan, provide unique up-to-date overviews of the history of galaxy formation and the evolution of the universe. Fascinating and comprehensive observational results as well as many important theoretical achievements were presented by more than 150 active researchers from more than 15 countries and regions. The conference started off with results from recent cutting-edge observations of the very high-redshift universe extending into the cosmic reionization era, together with some theoretical interpretations and predictions for the first generation of galaxies. The history of mass distributions and structure formation at later cosmic times, including clusters of galaxies, was discussed extensively in presentations based on various panoramic survey data sets. Our aim was to showcase and understand the intrinsic galaxy-formation bias in the high-redshift universe and also the role of external environmental effects during the hierarchical assembly of galaxies into denser regions. Various populations of distant galaxies at different redshifts, discovered and studies by many different techniques, were introduced along with the physical relationship between these populations. Our discussion were aimed at assembling these pieces of jigsaw puzzles together into a panoramic and yet detailed structures of the Milky Way Galaxy and the Local Group galaxies were also presented and discussed as a complementary approach to the studies of the high-redshift Universe. In total, 19 invited talks, 46 contributed talks, and 87 poster papers combined to build up a picture of the history of galaxies over the cosmic age. This book is suitable for researchers who are interested in both observational and theoretical aspects of galaxy formation and cosmology, and especially for students seeking an overview of knowledge about galaxy formation to date."--Publisher's website
Download or read book Investigating the Stellar Mass Growth and Quiescence of Massive Galaxies In the Early Universe Using Wide field Imaging written by Matthew Louis Stevans (Jr.) and published by . This book was released on 2019 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: While galaxies formed stars most actively around z=2, or ~3 Gyr after the Big Bang, when the universal star formation density in the universe peaked. By this time a population of massive galaxies had already formed 1011 - 1012 [solar mass] of stars and some had their star-formation shut off in a process known as quenching. Understanding how these massive galaxies build up their stellar mass and then quench so early in the universe is a fundamental observational test of galaxy evolution. If not obscured by dust, massive galaxies are very bright, and can be observed in the optical and infrared (IR) to probe their redshifted ultraviolet (UV) and optical emission, respectively. The UV emission is produced by newly formed O and B type stars within 100 Myrs of forming, while the rest-frame optical light is produced by stars of all type and traces the stellar mass in the galaxy. By measuring the UV and optical output of galaxies, astronomers can derive star-formation rates and stellar masses. Measuring these properties for large samples of galaxies across a wide dynamic range provides benchmarks for simulations of galaxy formation and evolution physics. The work in this dissertation focuses on completing a wide field imaging survey of galaxies with high UV star-formation rates and high stellar masses at high redshift to perform the most statistically robust census to date. In Chapter 1 we motivate measuring the UV output and the quiescent fraction of high-redshift galaxies. To measure the UV output of massive star-forming galaxies at high redshift we utilize an extensive multi-wavelength dataset assembled in the Spitzer HETDEX Exploratory Large Area Survey (SHELA) Field. The data set includes five bands of deep optical imaging from the Dark Energy Camera (DECam), deep 3.6 micron and 4.5 micron imaging for Spitzer, and J and K [subscript s] imaging for the VISTA-CFHT Stripe 82 (VICS82) Near-infrared Survey. Our extensive dataset compiled from both ground and space-based observatories is uniquely capable of studying the most actively star-forming galaxies which are often very massive galaxies residing in the rarest high-sigma density peaks of the cosmic web. In Chapter 2 we study the bright end of the z=4 galaxy UV luminosity distribution or luminosity function by fitting the spectral energy distributions (SEDs) of the galaxies in our photometric data with Stellar Population Synthesis (SPS) models to measure the galaxies' redshifts and UV luminosity. In addition to measuring the bright end of the galaxy luminosity function, we had the unanticipated result of measuring the faint end of the z=4 active galactic nuclei (AGN) UV luminosity function, which has implications on the contribution of AGNs during the end of the reionization era. We compare our observed galaxy luminosity function to luminosity functions predicted by semi-analytical models (SAMs) with different prescriptions for star formation physics, such as the density of neutral hydrogen. We find our observations are consistent with predictions that galaxies at z=3-4 form stars more efficiently than at lower redshifts due to shorter neutral hydrogen depletion times. In Chapter 3, we measure the fraction of massive (M [subscript *] > 1011 [solar mass] galaxies at z=3-5 in the largest volume to date. To do this we produce a K [subscript s] -selected catalog by combining deep K [subscript s] -band imaging from the NEWFIRM HETDEX survey (NHS), which we obtain, reduce, and catalog. We select quiescent galaxies by performing SED-fitting with SPS models to measure their redshifts, SFRs, and stellar masses. We define quiescent galaxies as having a specific SFR (sSFR; sSFR = SFR / stellar mass)

This book was released on 2013-11-11 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the second ESO workshop in aseries dedicated to science oppor tunities with the VLT. At the first workshop all areas of astronomical research were discussed. This second workshop is dedicated to research projects on the early Universe and has provided a forum for discussing strategies for studying faint distant objects in the optical and infrared spectral regions. This field is evolving very rapidly. There are several new surveys of galax ies and clusters of galaxies at intermediate redshift and quasars at very high redshift. Major advances in the morphological studies of distant galaxies, surveys of galaxies at high redshift and searches for primeval galaxies have been rendered possible by the new facilities provided by the Rubble Space Telescope and the Keck Telescope. Observational constraints on the evolution and formation of galaxies and large-scale structures as well as the cosmic chemical evolution were criti cally discussed with regard to theory and numerical simulations. In this context, the VLT first generation instrument capabilities were presented comprehensively and their use as cosmological tools discussed . The concluding remarks of the workshop focussed on the analysis of var ious possibilities for the VLT second generation instrumentation. Many of these topics were covered by invited reviews and talks, as well as some contributed talks. They are included in this volume together with the poster papers.
