Shear measurement bias due to spatially varying spectral energy distributions in galaxies

Kavli Affiliate: Patricia R. Burchat | First 5 Authors: Sowmya Kamath, Joshua E. Meyers, Patricia R. Burchat, , | Summary: Galaxy color gradients – i.e., spectral energy distributions that vary across the galaxy profile – will impact galaxy shape measurements when the modeled point spread function (PSF) corresponds to that for a galaxy with spatially […]

Reflections On the Anomalous ANITA Events: The Antarctic Subsurface as a Possible Explanation

Kavli Affiliate: Dustin M. Schroeder | First 5 Authors: Ian M. Shoemaker, Alexander Kusenko, Peter Kuipers Munneke, Andrew Romero-Wolf, Dustin M. Schroeder | Summary: The ANITA balloon experiment was designed to detect radio signals initiated by neutrinos and cosmic ray air showers. These signals are typically discriminated by the polarization and phase inversions of the […]

Candidate Massive Galaxies at $z sim 4$ in the Dark Energy Survey

Kavli Affiliate: Rafe Schindler | First 5 Authors: Pierandrea Guarnieri, Claudia Maraston, Daniel Thomas, Janine Pforr, Violeta Gonzalez-Perez | Summary: Using stellar population models, we predicted that the Dark Energy Survey (DES) – due to its special combination of area (5000 deg. sq.) and depth ($i = 24.3$) – would be in the position to […]

Classifying Signatures of Sudden Ionospheric Disturbances

Kavli Affiliate: Philip H. Scherrer | First 5 Authors: Sahil Hegde, Monica G. Bobra, Philip H. Scherrer, , | Summary: Solar activity, such as flares, produce bursts of high-energy radiation that temporarily enhance the D-region of the ionosphere and attenuate low-frequency radio waves. To track these Sudden Ionospheric Disturbances (SIDs), which disrupt communication signals and […]
