This book was released on 2009 with total page 660 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present the results of a multiwavelength study of the role mergers and (U)LIRGs have played in galaxy evolution using the COSMOS data set. First, we investigate the evolution of the galaxy pair fraction out to z = 1.2 by selecting pairs where both members are > L⋆V and have projected separations

This book was released on 2016-09-12 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents a pioneering method for gleaning the maximum information from the deepest images of the far-infrared universe obtained with the Herschel satellite, reaching galaxies fainter by an order of magnitude than in previous studies. Using these high-quality measurements, the author first demonstrates that the vast majority of galaxy star formation did not take place in merger-driven starbursts over 90% of the history of the universe, which suggests that galaxy growth is instead dominated by a steady infall of matter. The author further demonstrates that massive galaxies suffer a gradual decline in their star formation activity, providing an alternative path for galaxies to stop star formation. One of the key unsolved questions in astrophysics is how galaxies acquired their mass in the course of cosmic time. In the standard theory, the merging of galaxies plays a major role in forming new stars. Then, old galaxies abruptly stop forming stars through an unknown process. Investigating this theory requires an unbiased measure of the star formation intensity of galaxies, which has been unavailable due to the dust obscuration of stellar light.

Available in PDF, EPUB and Kindle. Book excerpt: A sweeping tour of the infrared universe as seen through the eyes of NASA’s Spitzer Space Telescope Astronomers have been studying the heavens for thousands of years, but until recently much of the cosmos has been invisible to the human eye. Launched in 2003, the Spitzer Space Telescope has brought the infrared universe into focus as never before. Michael Werner and Peter Eisenhardt are among the scientists who worked for decades to bring this historic mission to life. Here is their inside story of how Spitzer continues to carry out cutting-edge infrared astronomy to help answer fundamental questions that have intrigued humankind since time immemorial: Where did we come from? How did the universe evolve? Are we alone? In this panoramic book, Werner and Eisenhardt take readers on a breathtaking guided tour of the cosmos in the infrared, beginning in our solar system and venturing ever outward toward the distant origins of the expanding universe. They explain how astronomers use the infrared to observe celestial bodies that are too cold or too far away for their light to be seen by the eye, to conduct deep surveys of galaxies as they appeared at the dawn of time, and to peer through dense cosmic clouds that obscure major events in the life cycles of planets, stars, and galaxies. Featuring many of Spitzer’s spectacular images, More Things in the Heavens provides a thrilling look at how infrared astronomy is aiding the search for exoplanets and extraterrestrial life, and transforming our understanding of the history and evolution of our universe.

This book was released on 2016 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: The diffuse cosmological background light that pervades our Universe continues to be one of the best probes to uncover the astrophysical environments of the early Universe. In our attempt to gain a more holistic understanding of our present cosmological situation, we seek to understand the formation and evolution of the first stars and galaxies that came into existence. It is thought that these first-light galaxies are the progenitors to our Milky Way, and all other evolved galaxies. The spatial fluctuations of the extragalactic background light trace the total emission from all stars and galaxies in the Universe, and these first-light galaxies have left a measurable imprint on the cosmic infrared backgroud (CIB) light. In the first part of this thesis I describe measurements which suggest a detection of this signal, using a large subset of data from the largest allocation of Hubble time to date (CANDELS). This is followed by a cross-correlation analysis of the CIB with the cosmic X-ray background (CXB), which can give some insight as to whether or not X-ray emitting sources were present during this first-light epoch. I then shift towards the far-infrared (submillimeter) regime and discuss a statistical measurement of the redshift distribution of Herschel galaxies. Finally I show two-point correlation measurements of strongly lensed submillimeter galaxies, and the bias that this population may be introducing into past and current clustering analyses, which can lead to erroneous dark matter halo mass measurements from such studies.

Available in PDF, EPUB and Kindle. Book excerpt: We study the nature and clustering of infrared (IR) galaxies at z~1.5-3 in a 9 deg2 region from the Spitzer Deep, Wide-Field Survey (SDWFS) and the MIPS (Multiband Imaging Photometer for SIRTF) AGN (Active Galactic Nuclei) and Galaxy Evolution Survey (MAGES), taken at the Space Infrared Telescope Facility (SITRF). Using a method developed by Huang et al., we identify stellar-dominated IR-luminous galaxies at 1.5 z 3 by selecting objects with characteristic infrared (3.6, 4.5, and 8.0 micron) flux ratios and 24 micron flux density (S(24) hereafter) 0.3 mJy. We compute the angular correlation function of this sample over scales of 0.001 - 1 deg. Assuming an empirical redshift distribution, we derive spatial correlation scale lengths, r0 = 7.65 " 0.9 h−1 Mpc for S(24) 0.3 mJy and 8.73 " 2.1 h-1 Mpc for S(24)> 0.5 mJy, with a possible scale length increase at higher 24 micron flux densities. We compare our sample to IRluminous, dust-obscured galaxies (DOGs) at this redshift selected on the basis of their large mid-infrared to visible flux ratio, and which are known to include AGN, objects presumably powered by supermassive black hole accretion. While the DOG sample includes objects with S(24)> 1 mJy, our IR-luminous, stellar-dominated sample contains few bright objects, and is approximately limited to S(24)
