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…
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 (…
Constraints on Neutrino Physics from DESI DR2 BAO and DR1 Full Shape
W. Elbers, A. Aviles, H. E. Noriega +116
The Dark Energy Spectroscopic Instrument (DESI) Collaboration has obtained robust measurements of baryon acoustic oscillations (BAO) in the redshift range, , based o…
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…
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…
