  1. 832. Probing the Nature of Inflation

    Particle Physics / Physique des particules (PPD)
    Invited Speaker / Conférencier invité
    The idea that the early universe included an era of accelerated expansion (Inflation) was proposed to explain very qualitative features of the first cosmological observations. Since then, our observations have improved dramatically and have lead to high precision agreement with the predictions of the first models of inflation, slow-roll inflation. At the same time, there has been significant...

  2. 520. Determining Power Spectra of High Energy Cosmics

    Theoretical Physics / Physique théorique (DTP-DPT)
    Oral (Non-Student) / orale (non-étudiant)
    The angular power spectrum is a powerful observable for characterizing angular distributions, popularized by measurements of the cosmic microwave background (CMB). The power spectra of high energy cosmics ($\gamma$-rays, protons, neutrinos, etc.) contains information about their sources. Since these cosmics are observed on an event-by-event basis, the nature of the power spectrum measurement...

  3. 590. Searching for the echoes of inflation from a balloon - The first SPIDER flight
    Ivan Padilla (University of Toronto)

    Instrumentation and Measurement Physics / Physique des instruments et mesures (DIMP-DPIM)
    Oral (Student, In Competition) / Orale (Étudiant(e), inscrit à la compétition)
    SPIDER is a balloon-borne polarimeter designed to detect B-modes in the CMB at degree angular scales. Such a signal is a characteristic of early universe gravitational waves, a cornerstone prediction of inflationary theory. Hanging from a balloon at an altitude of 36 km allows the instrument to bypass 99% of the atmosphere and get an unobstructed view of the sky at 90 and 150 GHz. The...
