  • Astro Seminar: "Halo Bias and its Evolution in the Peak Model"

    David Rittenhouse Laboratory, A6

    Tobias Baldauf (IAS)

    The clustering statistics of galaxies and their host haloes in current and upcoming Large Scale Structure surveys have the potential to put stringent constraints on cosmology and fundamental physics. The understanding of these statistics is complicated by the fact that both the initial conditions and the evolution of halo statistics differ from the underlying matter statistics. We study these complications in the framework of the peak model by first establishing agreement of proto-halo density and momentum statistics in simulations and peak model predictions.

  • Astro Seminar: Unleashing the Power of ALMA

    David Rittenhouse Laboratory A6

    Amanda Kepley (NRAO)

    The Atacama Large Millimeter/submillimeter Array (ALMA) is a
    transformational millimeter interferometer being built in Chile that,
    when complete, will have 10-100 times the sensitivity, 100 times the
    resolution, and twice the wavelength coverage of existing millimeter
    interferometers. ALMA will be the premiere telescope for studying
    galaxy evolution and star and planet formation for the next several
    decades and, even in early science, is already revolutionizing our
    understanding of these important processes. In this talk, I will give

  • Special Seminar: "New Views on Iron Superconductivity: From a Mott Insulator’s Perspective"

    DRL Faculty Lounge

    Byron Freelon, M.I.T.

    Seeking to understand the nature of high-temperature superconductivity (HTSC) in iron-based materials, we discuss a new class of compounds in which unconventional superconductivity may occur.  When first discovered in 2008, superconductivity in iron-containing materials was thought to manifest by charge doping materials with metallic normal states.  By 2011, 

  • Astro Seminar: "Circumstellar Disk Composition and Evolution"

    David Rittenhouse Laboratory A6

    Alycia Weinberger (Carnegie Institution)

    Abstract:  The vast diversity of planetary systems arises from formation
    processes within circumstellar disks. These disks start out gas rich and end
    full of planets and some remnant debris dust. I will concentrate on stars in
    nearby young stellar associations and show how multi-wavelength imaging of
    their disks can reveal their compositions and dynamical states. I will
    highlight recent results with the Hubble Space Telescope and Magellan
    Adaptive Optics that both reveal the disks in amazing detail and hint at

  • Condensed Matter seminar: "Low-Dimensional Properties of Atomically-Thin Materials and Systems"

    DRL A4

    Douglas Strachan, University of Kentucky

    Atomically-thin materials represent the thinnest possible components of future device applications with extreme reduction in size scales. While tremendous progress has recently been made in understanding the large-scale properties of atomically-thin materials, the low-dimensional aspects, although critical to the smallest device sizes, have received comparatively much less attention.
