The DESI Data Release 1 white dwarf catalogue
Andrew Swan, Boris T. Gänsicke, Paula Izquierdo +49
The Dark Energy Spectroscopic Instrument is conducting a redshift survey, mapping the universe in three dimensions to measure the history of cosmic expansion. As well as extragalac…
Testing Scale-Dependent Modified Gravity with DESI DR1
D. Gonzalez, G. Niz, A. Aviles +42
The Dark Energy Spectroscopic Instrument (DESI) provides an unprecedented opportunity to test deviations from general relativity (GR) that introduce a new physical scale within its…
FolpsD: combining EFT and phenomenological approaches for joint power spectrum and bispectrum analyses
P. Bansal, A. Aviles, H. E. Noriega +56
We present a theoretical model for the power spectrum and bispectrum of galaxy clustering that exploits the complementarity between small-scale power spectrum information and large…
Cosmological constraints from the DESI DR1 joint power spectrum and bispectrum analysis
S. Novell-Masot, H. Gil-Marín, L. Verde +48
We derive cosmological parameter constraints from the Dark Energy Spectroscopic Instrument (DESI) Data Release 1 (DR1) galaxy clustering data, based on a joint full-shape analysis…
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…
Assembly bias and local Primordial non-Gaussianity from DESI DR1 Quasars
E. Fondi, L. Verde, E. Chaussidon +40
The analysis of the large-scale clustering of quasars (QSO) observed by the Dark Energy Spectroscopic Instrument (DESI) represents a promising avenue for constraining local Primord…
The DESI DR1 Peculiar Velocity Survey: growth rate measurements from the maximum likelihood fields method
Y. Lai, C. Howlett, J. Aguilar +60
We present the constraint on the growth rate of structure from the combination of DESI DR1 BGS sample, Fundamental Plane, and Tully-Fisher peculiar velocity catalogues using the ma…
Baryon Acoustic Oscillations from the C IV Forest with DESI DR2
Abby Bault, Andrei Cuceu, Julien Guy +53
We present a measurement of Baryon Acoustic Oscillations (BAO) in the cross-correlation of triply ionized carbon C IV absorption with the positions of quasars (QSO) and Emission Li…
Cosmological analysis of the DESI DR1 Lyman alpha 1D power spectrum
J. Chaves-Montero, A. Font-Ribera, P. McDonald +63
We present the cosmological analysis of the one-dimensional Lyman- flux power spectrum from the first data release of the Dark Energy Spectroscopic Instrument (DESI). We capture…
The Linear Point Standard Ruler with DESI DR1 and DR2 Data
N. Uberoi, F. Nikakhtar, N. Padmanabhan +45
The linear point, a purely geometric feature in the monopole of the two-point correlation function, has been proposed as an alternative standard ruler. Compared to the peak in the…
