Journal ArticleDOI
Second-Generation Design of Micro-Spec: A Medium-Resolution, Submillimeter-Wavelength Spectrometer-on-a-Chip
Giuseppe Cataldo,Emily M. Barrentine,Berhanu Bulcha,Negar Ehsan,Larry Hess,Omid Noroozian,Omid Noroozian,Omid Noroozian,Thomas R. Stevenson,Kongpop U-Yen,Edward J. Wollack,Samuel H. Moseley +11 more
TL;DR: The µ-Spec as discussed by the authors is a direct-detection spectrometer which integrates all the components of a diffraction-grating spectrometers onto a chip through the use of superconducting microstrip transmission lines.
Journal ArticleDOI
Backshort-Under-Grid arrays for infrared astronomy
Christine A. Allen,Dominic J. Benford,Jay Chervenak,David T. Chuss,Timothy M. Miller,Samuel H. Moseley,Johannes G. Staguhn,Edward J. Wollack +7 more
TL;DR: In this article, a kilopixel, filled bolometer array for space infrared astronomy is presented, which consists of three individual components, to be merged into a single working unit; a transition edge sensor bolometer arrays, operating in the milliKelvin regime, a quarter-wave backshort grid, and a superconducting quantum interference device multiplexer readout.
Journal ArticleDOI
The CLASS 150/220 GHz Polarimeter Array: Design, Assembly, and Characterization
Sumit Dahal,Mandana Amiri,John W. Appel,Charles L. Bennett,Lance Corbett,Rahul Datta,Kevin L. Denis,Thomas Essinger-Hileman,Mark Halpern,Kyle Helson,Gene C. Hilton,Johannes Hubmayr,Benjamin Keller,Tobias A. Marriage,Carolina Núñez,Matthew Petroff,Carl D. Reintsema,Karwan Rostem,Kongpop U-Yen,Edward J. Wollack +19 more
TL;DR: In this paper, the authors report on the development of a polarization-sensitive dichroic (150/220 GHz) detector array for the Cosmology Large Angular Scale Surveyor (CLASS) delivered to the telescope site in June 2019.
Journal ArticleDOI
Precision control of thermal transport in cryogenic single-crystal silicon devices
Karwan Rostem,David T. Chuss,Felipe Colazo,Erik Crowe,Kevin L. Denis,Nathan P. Lourie,Samuel H. Moseley,Thomas R. Stevenson,Edward J. Wollack +8 more
TL;DR: In this paper, the phonon mean-free-path (PMF) of a single-crystal silicon beam measured below 1 K was analyzed and shown to be a strong function of surface roughness characteristics of the beam.
Journal ArticleDOI
First Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Parameter Estimation Methodology
Licia Verde,Hiranya V. Peiris,David N. Spergel,M. R. Nolta,Charles L. Bennett,Mark Halpern,Gary Hinshaw,N. Jarosik,Alan J. Kogut,Michele Limon,S. S. Meyer,Lyman A. Page,Gregory S. Tucker,Gregory S. Tucker,Gregory S. Tucker,Edward J. Wollack,Edward L. Wright +16 more
TL;DR: In this article, the authors compare the WMAP measurements of the cosmic microwave background (CMB) and other complementary data sets to theoretical models, using the Monte Carlo Markov Chains to explore the likelihood of the data given a model to determine the best fit cosmological parameters and their uncertainties.
