Analytic bispectrum covariance for galaxy survey cosmology
Utkarsh Giri, Henry S. Grasshorn Gebhardt, Olivier Dore
The bispectrum of galaxy distribution remains an underutilized statistic in cosmological data analysis. This can be attributed to mathematical and computational challenges associat…
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…
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…
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…
Validation of Spherical Fourier-Bessel power spectrum analysis with lognormal simulations and eBOSS DR16 LRG EZmocks
Henry Grasshorn Gebhardt, Olivier Doré
Tuning into the bass notes of the large-scale structure requires careful attention to geometrical effects arising from wide angles. The spherical Fourier-Bessel (SFB) basis provide…
Fast Theoretical Predictions for Spherical Fourier Analysis of Large-Scale Structures
Brandon Khek, Henry S. Grasshorn Gebhardt, Olivier Doré
On-going or soon to come cosmological large-scale structure surveys such as DESI, SPHEREx, Euclid, or the High-Latitude Spectroscopic Survey of the Nancy Grace Roman Space Telescop…
Harmonic analysis of isotropic fields on the sphere with arbitrary masks
Henry S. Grasshorn Gebhardt, Olivier Doré
Obtaining constraints from the largest scales of a galaxy survey is challenging due to the survey mask allowing only partial measurement of large angular modes. This scatters infor…
SuperFaB: a fabulous code for Spherical Fourier-Bessel decomposition
Henry S. Grasshorn Gebhardt, Olivier Doré
The spherical Fourier-Bessel (SFB) decomposition is a natural choice for the radial/angular separation that allows extraction of cosmological information from large volume galaxy s…
The Rest-Frame Optical Morphology of Emission Line Galaxies at 2 < z < 3: Evidence for Inside-Out Formation in Low-Mass Galaxies
Alex Hagen, Nicholas A. Bond, Robin Ciardullo +6
We compare the rest-frame ultraviolet and rest-frame optical morphologies of 2 < z < 3 star-forming galaxies in the GOODS-S field using Hubble Space Telescope WFC3 and ACS images f…
HST Emission Line Galaxies at z ~ 2: Comparing Physical Properties of Lyman Alpha and Optical Emission Line Selected Galaxies
Alex Hagen, Gregory R. Zeimann, Christoph Behrens +14
We compare the physical and morphological properties of z ~ 2 Lyman-alpha emitting galaxies (LAEs) identified in the HETDEX Pilot Survey and narrow band studies with those of z ~ 2…
Young, Star-forming Galaxies and their local Counterparts: the Evolving Relationship of Mass-SFR-Metallicity since z ~ 2.1
Henry S. Grasshorn Gebhardt, Gregory R. Zeimann, Robin Ciardullo +5
We explore the evolution of the Stellar Mass-Star Formation Rate-Metallicity Relation using a set of 256 COSMOS and GOODS galaxies in the redshift range 1.90 < z < 2.35. We present…
