Is DESI Seeing Dynamical Dark Energy, or a Cosmic Glitch in Gravity?
Robin Y. Wen, Lukas Tobias Hergt, Niayesh Afshordi +1
Combined baryon acoustic oscillation and cosmic microwave background data have begun to mildly favor departures from . This is usually framed as 2-parameter dynamica…
Impact and measurability of linear relativistic effects in galaxy surveys
Robin Y. Wen, Henry S. Grasshorn Gebhardt, Olivier Doré
The three-dimensional galaxy power spectrum is a powerful probe of primordial non-Gaussianity (PNG) and additional general relativistic (GR) effects on large scales, which can be c…
Demonstrating the Use of the Spherical Fourier Bessel Basis for Large Scale Clustering Systematics Discovery and Mitigation with eBOSS
Sean Bruton, James R. Cheshire, Olivier Doré +2
The spherical Fourier-Bessel (SFB) basis, in separating the angular and radial modes of the power spectrum, permits a targeted identification and mitigation of systematics in clust…
SPHEREx Wide-Field Infrared Spectral Mapping of Interstellar Ices and Polycyclic Aromatic Hydrocarbons
Joseph L. Hora, Jinyoung K. Noh, Gary J. Melnick +32
We present some of the first infrared spectral maps acquired by SPHEREx. These maps, which to our knowledge are the largest of their type ever compiled in the near-infrared, reveal…
SPHEREx mapping of diffuse PAH and H II emission in the Galactic plane
Giulia Murgia, Ari J. Cukierman, Brandon S. Hensley +29
We present preliminary SPHEREx maps of diffuse Galactic emission tracing polycyclic aromatic hydrocarbons (PAHs) and ionized hydrogen gas, and we study their relationship across th…
Large-scale Modeling of the Observed Power Spectrum Multipoles
Robin Y. Wen, Henry S. Grasshorn Gebhardt, Chen Heinrich +1
Current and upcoming large-scale structure surveys are pushing toward increasingly wide angular coverage, where wide-angle effects (arising from the varying line of sight across th…
