Axion decay and anisotropy of near-IR extragalactic background light
Yan Gong, Asantha Cooray, Ketron Mitchell-Wynne +3
The extragalactic background light (EBL) is comprised of the cumulative radiation from all galaxies and active galactic nuclei over the cosmic history. In addition to point sources…
Ultraviolet Luminosity Density of the Universe During the Epoch of Reionization
Ketron Mitchell-Wynne, Asantha Cooray, Yan Gong +9
The spatial fluctuations of the extragalactic background light trace the total emission from all stars and galaxies in the Universe. A multi-wavelength study can be used to measure…
The Hydroxyl-Water Megamaser Connection. I. Water Emission Toward OH Megamaser Hosts
Brandon K. Wiggins, Victor Migenes, Joseph M. Smidt
Questions surround the connection of luminous extragalactic masers to galactic processes. The observation that water and hydroxyl megamasers rarely coexist in the same galaxy has g…
Assessing the Observability of Hypernovae and Pair-Instability Supernovae in the Early Universe
Brandon K. Wiggins, Joseph M. Smidt, Daniel J. Whalen +3
The era of the universe's first (Population III) stars is essentially unconstrained by observation. Ultra-luminous and massive stars from this time altered the chemistry of the cos…
Measurements of the mean diffuse galactic light spectrum in the 0.95 μm to 1.65 μm band from CIBER
T. Arai, S. Matsuura, J. Bock +13
We report measurements of the Diffuse Galactic Light (DGL) spectrum in the near-infrared, spanning the wavelength range 0.95-1.65 μm by the Cosmic Infrared Background ExpeRiment (C…
Planck Trispectrum Constraints on Primordial Non-Gaussianity at Cubic Order
Chang Feng, Asantha Cooray, Joseph Smidt +3
Non-Gaussianity of the primordial density perturbations provides an important measure to constrain models of inflation. At cubic order the non-Gaussianity is captured by two parame…
