The DESI DR1 Peculiar Velocity Survey: The Tully-Fisher Distance Catalog
K. Douglass, S. BenZvi, A. G. Kim +64
We calibrate the Tully-Fisher relation (TFR) using observations of spiral galaxies taken during the first year (DR1) of the DESI galaxy redshift survey. The rotational velocities o…
The DESI DR1 Peculiar Velocity Survey: Fundamental Plane Catalogue
C. E. Ross, C. Howlett, J. R. Lucey +58
Measurements of peculiar velocities in the local Universe are a powerful tool to study the nature of dark energy at low () redshifts. Here we present the largest single se…
Probing the limits of cosmological information from the Lyman- forest 2-point correlation functions
Wynne Turner, Andrei Cuceu, Paul Martini +48
The standard cosmological analysis with the Ly forest relies on a continuum fitting procedure that suppresses information on large scales and distorts the three-dimensional corr…
DESI DR1 Lyα 1D power spectrum: The Fast Fourier Transform estimator measurement
Corentin Ravoux, Marie-Lynn Abdul-Karim, Jean-Marc Le Goff +64
We present the one-dimensional Lyman- forest power spectrum measurement derived from the data release 1 (DR1) of the Dark Energy Spectroscopic Instrument (DESI). The measurement…
Extended Dark Energy analysis using DESI DR2 BAO measurements
K. Lodha, R. Calderon, W. L. Matthewson +122
We conduct an extended analysis of dark energy constraints, in support of the findings of the DESI DR2 cosmology key paper, including DESI data, Planck CMB observations, and three…
The Cosmic Evolution of CIV Absorbers at : Insights from Systems in DESI Quasars
Abhijeet Anand, J. Aguilar, S. Ahlen +39
We present the largest catalog to date of triply ionized carbon (CIV) absorbers detected in quasar spectra from the Dark Energy Spectroscopic Instrument. Using an automated matched…
Dynamical Dark Energy in light of the DESI DR2 Baryonic Acoustic Oscillations Measurements
Gan Gu, Xiaoma Wang, Yuting Wang +57
Understanding whether cosmic acceleration arises from a cosmological constant or a dynamical component is a central goal of cosmology, and the Dark Energy Spectroscopic Instrument…
Full-Shape analysis of the power spectrum and bispectrum of DESI DR1 LRG and QSO samples
S. Novell-Masot, H. Gil-Marín, L. Verde +66
We present the first joint analysis of the power spectrum and bispectrum using the Data Release 1 (DR1) of the Dark Energy Spectroscopic Instrument (DESI), focusing on Luminous Red…
