Full calibration of the tomographic redshift distribution from the HSC PDR3 Shape Catalog with DESI
J. Choppin de Janvry, S. Gontcho A Gontcho, U. Seljak +53
The calibration of tomographic redshift distributions is essential for cosmological analysis of weak lensing data. In this work, we calibrate all four tomographic bins of the Hyper…
Without the Sound Horizon (or Supernovae): A 2% Measurement in DESI DR1
E. A. Zaborowski, P. Taylor, K. Honscheid +58
The sound horizon scale is a key source of information for early-time measurements, and is therefore a common target of new physics proposed to solve the Hubble tension…
Clustering analysis of medium-band selected high-redshift galaxies
H. Ebina, M. White, A. Raichoor +57
Next-generation large-scale structure spectroscopic surveys will probe cosmology at high redshifts , relying on abundant galaxy tracers such as Ly emitters (LAE…
Is Dark Energy Increasing or Decreasing in the Late Universe?
Maryam Aghaei Abchouyeh, Maurice H. P. M. van Putten
The concordance cosmological model CDM assumes dark energy to be a constant, consistent with early-time observations, evidenced by Planck-CDM analyses. However, in the face o…
DESI Strong Lens Foundry III: Keck Spectroscopy for Strong Lenses Discovered Using Residual Neural Networks
Shrihan Agarwal, Xiaosheng Huang, William Sheu +49
We present spectroscopic data of strong lenses and their source galaxies using the Keck Near-Infrared Echellette Spectrometer (NIRES) and the Dark Energy Spectroscopic Instrument (…
Fiducial-Cosmology-dependent systematics for the DESI 2024 Full-Shape Analysis
R. Gsponer, S. Ramirez-Solano, F. Rodríguez-Martínez +65
We assess the impact of the fiducial cosmology choice on cosmological inference from full-shape (FS) fits of the galaxy power spectrum in the DESI 2024 Data Release 1 (DR1). Using…
Combined tracer analysis for DESI 2024 BAO
D. Valcin, M. Rashkovetskyi, H. Seo +64
This paper demonstrates how the Dark Energy Spectroscopic Instrument (DESI) Data Release 1 (DR1) and future baryon acoustic oscillations (BAO) analyses can optimally combine overla…
Clustering of DESI galaxies split by thermal Sunyaev-Zeldovich effect
M. Rashkovetskyi, D. J. Eisenstein, J. Aguilar +46
The thermal Sunyaev-Zeldovich (tSZ) effect is associated with galaxy clusters - extremely large and dense structures tracing the dark matter with a higher bias than isolated galaxi…
Frequentist Cosmological Constraints from Full-Shape Clustering Measurements in DESI DR1
James Morawetz, Hanyu Zhang, Marco Bonici +53
We present a frequentist analysis of clustering measurements from Data Release 1 of the Dark Energy Spectroscopic Instrument (DESI) using the standard profile likelihood method. Wh…
Spectroscopic Characterization of redMaPPer Galaxy Clusters with DESI
J. Myles, D. Gruen, T. Jeltema +44
Optical galaxy cluster identification algorithms such as redMaPPer promise to enable an array of astrophysical and cosmological studies, but suffer from biases whereby galaxies in…
Model-Independent Measurement of the Matter-Radiation Equality Scale in DESI 2024
B. Bahr-Kalus, D. Parkinson, K. Lodha +52
The peak of the matter power spectrum, known as the turnover (TO) scale, is determined by the horizon size at the time of matter-radiation equality. This scale can serve as a stand…
