A Path to an All-Sky Survey with Roman
Jiwon Jesse Han, Anirudh Chiti, Kai-Feng Chen +93
A deep, space-based, all-sky near-infrared survey carried out with the Nancy Grace Roman Space Telescope would constitute a foundational astronomical infrastructure for decades to…
First Detection of the Baryon Acoustic Oscillation (BAO) Feature in the 3-Point Correlation Function of DESI DR1 Luminous Red Galaxies
Farshad Kamalinejad, Zachary Slepian, Alex Krolewski +55
We present the first detection of the 3-Point Correlation Function (3PCF) Baryon Acoustic Oscillation (BAO) signal from the DESI Data Release 1 (DR1) sample of Luminous Red Galaxie…
Illuminating the Physics of Cosmic Origin and Evolution: A UK Space Frontiers 2035 White Paper
Florian Beutler, Eva-Maria Mueller, Seshadri Nadathur +61
Understanding the Universe's origins and evolution remains one of the most fundamental challenges in modern cosmology. This white paper explores three key science priorities in thi…
Can the CMB be Odd? Effect of a Parity-Violating Matter 4-Point Function on the Low- CMB Trispectrum
Zachary Slepian, Matthew Reinhard, Michael Bartlett
Here we explore from a theoretical perspective the sensitivity of the primary CMB anisotropy trispectrum to parity violation (PV) in large-scale structure (LSS). We focus on the Sa…
Analytical Template for the 4-Point Correlation Function Covariance Beyond the Gaussian Random Field : 1-Loop Corrections with Third-Order Densities
William Ortolá Leonard, Zachary Slepian
Analytical templates for the 4-Point Correlation Function (4PCF) covariance matrix have been developed in the past assuming a Gaussian Random Field (GRF). In this work, we present…
Analytical Template for the 4-Point Correlation Function Covariance Beyond the Gaussian Random Field : 1-Loop Corrections involving Second-Order Densities
William Ortolá Leonard, Zachary Slepian
Analytical templates for the covariance matrix of the 4-Point Correlation Function (4PCF) have been developed in the past assuming a Gaussian Random Field (GRF). In this work, we p…
