Abstract: Measurements in the infrared wavelength domain allow us to assess directly the physical state and energy balance of cool matter in space, thus enabling the detailed study of the various processes that govern the formation and early evolution of stars and planetary systems in galaxies over cosmic time.
This finding provides important insights on the growth of supermassive black holes over cosmic time.
«Exploding stars prove Newton's law of gravity unchanged over cosmic time.»
Science Interests Formation of galaxies and black holes in the early universe and their growth over cosmic time; large surveys with Hubble and other telescopes to discover new populations of distant galaxies and black holes; physical properties of active galactic nuclei using observations from radio, infrared, optical, ultraviolet through to X-ray energies.
By developing and bringing to bear innovative spectroscopic and high resolution imaging instruments on large ground - based telescopes and space telescopes, he and his team have been studying massive black holes in the centers of galaxies (including our own), galactic star formation over cosmic time, and the evolution of galaxies in the Early Universe.
In particular, SPICA will have the unique ability to trace the evolution of the obscured SFRD and BHARD over cosmic time, from the peak of their activity back to the reionisation epoch (i.e., 3 < z < 6 - 7), where its predecessors had severe limitations.
«The 3 - D information is vital to studying the evolution of the structures over cosmic time,» said Jason Rhodes, a collaborator in the study at the Jet Propulsion Laboratory in Pasadena, Calif..
With this exceptional leap in performance, new domains in infrared astronomy will become accessible, allowing us, for example, to unravel definitively galaxy evolution and metal production over cosmic time, to study dust formation and evolution from very early epochs onwards, and to trace the formation history of planetary systems.
«Zooming into the maps, we have measured how dark matter envelops galaxies of different types and how together they evolve over cosmic time.
Dr. Jean Brodie, from the University of California at Santa Cruz, will trace the formation and evolution of galaxies over cosmic time, making use of some «astronomical fossils» called globular star clusters, that are bright beacons tracing all the mergers and acquisitions that have assembled into present day galaxies.
He continues, «We hope to expand our research to farther expanses of the universe by utilizing the superb capability of ALMA to help us understand comprehensively the growth of supermassive black holes over cosmic time.»
«It is pretty clear that you first make small seed black holes in the early universe, and over cosmic time, by swallowing gas in their vicinity, they grow,» said study co-author Priya Natarajan, a Yale astrophysicist.
«Our cosmological analysis complements experimental efforts to describe and constrain the laws of physics in a new way and over cosmic time.»
Although the Universe itself, and galaxies within it, has evolved over cosmic time, globular clusters are very robust and many have survived intact for over 10 billion years.
In this talk, UC Berkeley's Dr. Mariska Kriek will present recent studies of galaxies in the Early Universe, and discuss our current view of how different types of galaxies may have formed and evolved over cosmic time.
«Using the galaxy technique, DLAs can be studied in large numbers to provide a 3 - D tomographic picture of distribution of gas clouds in the early Universe and help complete our understanding of how galaxies formed and evolved over cosmic time,» O'Meara said.
