Model-independent consistency tests of DESI DR2 BAO and SN Ia
Hyeok Woo, William Luke Matthewson, Arman Shafieloo
Cosmic distances can be measured using two complementary probes: Type Ia supernovae (SN Ia), serving as standard candles, and baryon acoustic oscillations (BAO), serving as standar…
Braneworld Dark Energy in light of DESI DR2
Swagat S. Mishra, William L. Matthewson, Varun Sahni +2
Recent observational results from the DESI collaboration reveal tensions with the standard CDM model and favour a scenario in which dark energy (DE) decays over time. The DESI D…
Cosmological implications of DESI DR2 BAO measurements in light of the latest ACT DR6 CMB data
C. Garcia-Quintero, H. E. Noriega, A. de Mattia +92
We report cosmological results from the Dark Energy Spectroscopic Instrument (DESI) measurements of baryon acoustic oscillations (BAO) when combined with recent data from the Ataca…
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…
Validation of the DESI DR2 Measurements of Baryon Acoustic Oscillations from Galaxies and Quasars
U. Andrade, E. Paillas, J. Mena-Fernández +116
The Dark Energy Spectroscopic Instrument (DESI) data release 2 (DR2) galaxy and quasar clustering data represents a significant expansion of data from DR1, providing improved stati…
DESI DR2 Results I: Baryon Acoustic Oscillations from the Lyman Alpha Forest
DESI Collaboration, M. Abdul-Karim, J. Aguilar +147
We present the Baryon Acoustic Oscillation (BAO) measurements with the Lyman-alpha (LyA) forest from the second data release (DR2) of the Dark Energy Spectroscopic Instrument (DESI…
DESI DR2 Results II: Measurements of Baryon Acoustic Oscillations and Cosmological Constraints
DESI Collaboration, M. Abdul-Karim, J. Aguilar +184
We present baryon acoustic oscillation (BAO) measurements from more than 14 million galaxies and quasars drawn from the Dark Energy Spectroscopic Instrument (DESI) Data Release 2 (…
DESI 2024 VII: Cosmological Constraints from the Full-Shape Modeling of Clustering Measurements
DESI Collaboration, A. G. Adame, J. Aguilar +210
We present cosmological results from the measurement of clustering of galaxy, quasar and Lyman- forest tracers from the first year of observations with the Dark Energy Spectrosc…
DESI 2024: Constraints on Physics-Focused Aspects of Dark Energy using DESI DR1 BAO Data
K. Lodha, A. Shafieloo, R. Calderon +47
Baryon acoustic oscillation data from the first year of the Dark Energy Spectroscopic Instrument (DESI) provide near percent-level precision of cosmic distances in seven bins over…
DESI 2024: Reconstructing Dark Energy using Crossing Statistics with DESI DR1 BAO data
R. Calderon, K. Lodha, A. Shafieloo +52
We implement Crossing Statistics to reconstruct in a model-agnostic manner the expansion history of the universe and properties of dark energy, using DESI Data Release 1 (DR1) BAO…
Constraining primordial non-Gaussianity using two galaxy surveys and CMB lensing
Mario Ballardini, William Luke Matthewson, Roy Maartens
Next-generation galaxy surveys will be able to measure perturbations on scales beyond the equality scale. On these ultra-large scales, primordial non-Gaussianity leaves signatures…
