Photographing the wave function of the Universe
C. R. Contaldi, R. Bean, J. Magueijo
We show that density fluctuations in standard inflationary scenarios may take the most general non-Gaussian distribution if the wave function of the Universe is not in the ground s…
3D atomic structure from a single XFEL pulse
G. Bortel, M. Tegze, M. Sikorski +10
X-ray Free Electron Lasers (XFEL) are the most advanced pulsed x-ray sources. Their extraordinary pulse parameters promise unique applications. Indeed, several new methods have bee…
Wilkinson Microwave Anisotropy Probe (WMAP) Three Year Results: Implications for Cosmology
D. N. Spergel, R. Bean, O. Doré +19
A simple cosmological model with only six parameters (matter density, Omega_m h^2, baryon density, Omega_b h^2, Hubble Constant, H_0, amplitude of fluctuations, sigma_8, optical de…
Data Release 1 of the Dark Energy Spectroscopic Instrument
DESI Collaboration, M. Abdul Karim, A. G. Adame +306
In 2021 May the Dark Energy Spectroscopic Instrument (DESI) collaboration began a 5-year spectroscopic redshift survey to produce a detailed map of the evolving three-dimensional s…
Wide-Field InfraRed Survey Telescope (WFIRST) Final Report
J. Green, P. Schechter, C. Baltay +51
In December 2010, NASA created a Science Definition Team (SDT) for WFIRST, the Wide Field Infra-Red Survey Telescope, recommended by the Astro 2010 Decadal Survey as the highest pr…
The Simons Observatory: forecasted constraints on primordial gravitational waves with the expanded array of Small Aperture Telescopes
The Simons Observatory Collaboration, I. Abril-Cabezas, S. Adachi +479
We present updated forecasts for the scientific performance of the degree-scale (0.5 deg FWHM at 93 GHz), deep-field survey to be conducted by the Simons Observatory (SO). By 2027,…
Measuring in the Early Universe: CMB Polarization, Reionization and the Fisher Matrix Analysis
G. Rocha, R. Trotta, C. J. A. P. Martins +4
We present a detailed analysis of present and future Cosmic Microwave Background constraints of the value of the fine-structure constant, . We carry out a more detailed analysi…
Three Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Polarization Analysis
L. Page, G. Hinshaw, E. Komatsu +20
The Wilkinson Microwave Anisotropy Probe WMAP has mapped the entire sky in five frequency bands between 23 and 94 GHz with polarization sensitive radiometers. We present three-year…
Three-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Beam Profiles, Data Processing, Radiometer Characterization and Systematic Error Limits
N. Jarosik, C. Barnes, M. R. Greason +18
The WMAP satellite has completed 3 years of observations of the cosmic microwave background radiation. The 3-year data products include several sets of full sky maps of the Stokes…
Measuring in the Early Universe: CMB Temperature, Large-Scale Structure and Fisher Matrix Analysis
C. J. A. P. Martins, A. Melchiorri, R. Trotta +4
We extend our recent work on the effects of a time-varying fine-structure constant in the cosmic microwave background, by providing a thorough analysis of the degeneracies bet…
The Whole is Greater than the Sum of the Parts: Optimizing the Joint Science Return from LSST, Euclid and WFIRST
B. Jain, D. Spergel, R. Bean +26
The focus of this report is on the opportunities enabled by the combination of LSST, Euclid and WFIRST, the optical surveys that will be an essential part of the next decade's astr…
