A Map of Diffuse Radio Emission at 182 MHz to Enhance Epoch of Reionization Observations in the Southern Hemisphere
Ruby Byrne, Miguel F. Morales, Bryna Hazelton +5
We present a broadband map of polarized diffuse emission at 167-198 MHz developed from data from the Murchison Widefield Array (MWA). The map is designed to improve visibility simu…
First Season MWA Phase II EoR Power Spectrum Results at Redshift 7
W. Li, J. C. Pober, N. Barry +44
The compact configuration of Phase II of the Murchison Widefield Array (MWA) consists of both a redundant subarray and pseudo-random baselines, offering unique opportunities to per…
Understanding the Diversity of 21 cm Cosmology Analyses
Miguel F. Morales, Adam Beardsley, Jonathan Pober +4
21 cm power spectrum observations have the potential to revolutionize our understanding of the Epoch of Reionization and Dark Energy, but require extraordinarily precise data analy…
Delay Spectrum with Phase-Tracking Arrays: Extracting the HI power spectrum from the Epoch of Reionization
Sourabh Paul, Shiv K. Sethi, Miguel F. Morales +51
The Detection of redshifted 21 cm emission from the epoch of reionization (EoR) is a challenging task owing to strong foregrounds that dominate the signal. In this paper, we propos…
First Limits on the 21 cm Power Spectrum during the Epoch of X-ray heating
A. Ewall-Wice, Joshua S. Dillon, J. N. Hewitt +62
We present first results from radio observations with the Murchison Widefield Array seeking to constrain the power spectrum of 21 cm brightness temperature fluctuations between the…
Confirmation of Wide-Field Signatures in Redshifted 21 cm Power Spectra
Nithyanandan Thyagarajan, Daniel C. Jacobs, Judd D. Bowman +52
We confirm our recent prediction of the "pitchfork" foreground signature in power spectra of high-redshift 21 cm measurements where the interferometer is sensitive to large-scale s…
The Cosmic Infrared Background Experiment (CIBER): the Narrow Band Spectrometer
P. M. Korngut, T. Renbarger, T. Arai +21
We have developed a near-infrared spectrometer designed to measure the absolute intensity of the Solar 854.2 nm CaII Fraunhofer line, scattered by interplanetary dust, in the Zodia…
Measuring Light from the Epoch of Reionization with CIBER, the Cosmic Infrared Background Experiment
Michael Zemcov, Toshiaki Arai, John Battle +17
Ultraviolet emission from the first generation of stars in the Universe ionized the intergalactic medium in a process which was completed by z~6; the wavelength of these photons ha…
Mid-Infrared Variability from the Spitzer Deep, Wide-Field Survey
Szymon Kozlowski, Christopher S. Kochanek, Daniel Stern +30
We use the multi-epoch, mid-infrared Spitzer Deep, Wide-Field Survey to investigate the variability of 474,179 objects in 8.1 deg^2 of the NDWFS Bootes field. We perform a Differen…
The Spitzer Deep, Wide-Field Survey
M. L. N. Ashby, D. Stern, M. Brodwin +30
The Spitzer Deep, Wide-Field Survey (SDWFS) is a four-epoch infrared survey of ten square degrees in the Bootes field of the NOAO Deep Wide-Field Survey using the IRAC instrument o…
Cosmic Infrared Background ExpeRiment (CIBER): A Probe of Extragalactic Background Light from Reionization
Asantha Cooray, James J. Bock, Mitsunobu Kawada +11
The Cosmic Infrared Background ExpeRiment (CIBER) is a rocket-borne absolute photometry imaging and spectroscopy experiment optimized to detect signatures of first-light galaxies p…
A New Era in Extragalactic Background Light Measurements: The Cosmic History of Accretion, Nucleosynthesis and Reionization
Asantha Cooray, Alexandre Amblard, Charles Beichman +52
(Brief Summary) What is the total radiative content of the Universe since the epoch of recombination? The extragalactic background light (EBL) spectrum captures the redshifted ener…
