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…
The SPHEREx Satellite Mission
James J. Bock, Asad M. Aboobaker, Joseph Adamo +111
SPHEREx, a NASA explorer satellite launched on 11 March 2025, is carrying out the first all-sky near-infrared spectral survey. The satellite observes in 102 spectral bands from 0.7…
Separating Angular and Radial Modes with Spherical-Fourier Bessel Power Spectrum on All Scales and Implications for Systematics Mitigation
Robin Y. Wen, Henry S. Grasshorn Gebhardt, Chen Heinrich +1
Current and upcoming large-scale structure surveys place stringent requirements on the mitigation of observational systematics in order to achieve their unprecedented constraining…
Linear Relativistic Corrections in the Spherical Fourier-Bessel Power Spectrum
Robin Y. Wen, Henry S. Grasshorn Gebhardt, Chen Heinrich +1
The three-dimensional galaxy power spectrum is a powerful probe of primordial non-Gaussianity and additional general relativistic (GR) effects on large scales, which can be constra…
Wide-Angle Effects in the Power Spectrum Multipoles in Next-Generation Redshift Surveys
Joshua N. Benabou, Isabel Sands, Henry S. Grasshorn Gebhardt +2
As galaxy redshift surveys expand to larger areas on the sky, effects coming from the curved nature of the sky become important, introducing wide-angle (WA) corrections to the powe…
Exact Modeling of Power Spectrum Multipole through Spherical Fourier-Bessel Basis
Robin Y. Wen, Henry S. Grasshorn Gebhardt, Chen Heinrich +1
The three-dimensional galaxy power spectrum is a powerful probe of primordial non-Gaussianity and additional general relativistic effects, which become important on large scales. A…
The Galaxy Bispectrum in the Spherical Fourier-Bessel Basis
Joshua N. Benabou, Adriano Testa, Chen Heinrich +2
The bispectrum, the three-point correlation in Fourier space, is a crucial statistic for studying many effects targeted by the next-generation galaxy surveys, such as primordial no…
Measuring with the SPHEREx Multi-tracer Redshift Space Bispectrum
Chen Heinrich, Olivier Dore, Elisabeth Krause
The bispectrum is an important statistics helpful for measuring the primordial non-Gaussianity parameter to less than order unity in error, which would allow us t…
