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…
Deep Spectroscopy with DESI for Photometric Redshift Training and Calibration
Biprateep Dey, Jeffrey A. Newman, Tianqing Zhang +62
Deep spectroscopic samples can be used to improve photometric redshift (photo-) estimates and reduce uncertainties on redshift distributions. Such improvements can increase the…
The DESI Transients Survey: Legacy Classifications and Methodology
Xander J. Hall, Antonella Palmese, Segev BenZvi +56
We present the first systematic spectroscopic observations of extragalactic transients from the Dark Energy Spectroscopic Instrument (DESI), as part of the DESI Transients Survey p…
Cosmology from Planck CMB Lensing and DESI DR1 Quasar Tomography
R. de Belsunce, A. Krolewski, S. Chiarenza +60
We present a measurement of the amplitude of matter fluctuations over the redshift range 0.8 <= z <= 3.5 from the cross correlation of over 1.2 million spectroscopic quasars select…
