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…
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…
A glitch in gravity: cosmic Lorentz-violation from fiery Big Bang to glacial heat death
Robin Y. Wen, Lukas T. Hergt, Niayesh Afshordi +1
One regime where we might see departures from general relativity is at the largest accessible scales, with a natural choice in cosmology being the cosmological horizon (or Hubble)…
Separable ellipsoids around multipartite states
Robin Y. Wen, Gilles Parez, Liuke Lyu +2
We show that, in finite dimensions, around any -partite product state , there exists an ellipsoid of separable states centered around $ρ_{\…
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…
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…
Hierarchical Bayesian Inference of Globular Cluster Properties
Robin Y. Wen, Joshua S. Speagle, Jeremy J. Webb +1
We present a hierarchical Bayesian inference approach to estimating the structural properties and the phase space center of a globular cluster (GC) given the spatial and kinematic…
A cosmic glitch in gravity
Robin Y. Wen, Lukas T. Hergt, Niayesh Afshordi +1
We investigate a model that modifies general relativity on cosmological scales, specifically by having a `glitch' in the gravitational constant between the cosmological (super-hori…
Separable Ball around any Full-Rank Multipartite Product State
Robin Yunfei Wen, Achim Kempf
We show that around any -partite product state of full rank (that is , there exists a finite-sized closed…
The Transfer of Entanglement Negativity at the Onset of Interactions
Robin Yunfei Wen, Achim Kempf
Quantum information, in the form of entanglement with an ancilla, can be transmitted to a third system through interaction. Here, we investigate this process of entanglement transm…
