Fast Holographic Deconvolution: a new technique for precision radio interferometry
Ian Sullivan, Miguel Morales, Bryna Hazelton +48
We introduce the Fast Holographic Deconvolution method for analyzing interferometric radio data. Our new method is an extension of A-projection/software-holography/forward modeling…
Contribution to Unresolved Infrared Fluctuations from Dwarf Galaxies at Redshifts of 2-3
Ranga-Ram Chary, Asantha Cooray, Ian Sullivan
In order to understand the origin of clustered anisotropies detected in Spitzer images between 3.6 and 8 microns, we stack the Spitzer IRAC/Great Observatories Origins Deep Survey…
IR Background Anisotropies in Spitzer GOODS images and constraints on first galaxies
Asantha Cooray, Ian Sullivan, Ranga-Ram Chary +6
We describe the angular power spectrum of unresolved 3.6 micron IR light in Spitzer GOODS fields. The amplitude of the anisotropy spectrum decreases with decreasing flux threshold…
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…
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…
Every Datapoint Counts: Stellar Flares as a Case Study of Atmosphere Aided Studies of Transients in the LSST Era
Riley W. Clarke, James R. A. Davenport, John Gizis +8
Due to their short timescale, stellar flares are a challenging target for the most modern synoptic sky surveys. The upcoming Vera C. Rubin Legacy Survey of Space and Time (LSST), a…
