Cosmological inference from a joint DESI DR1 full-shape power spectrum and bispectrum analysis
Caroline Guandalin, Prakhar Bansal, Pedro Carrilho +11
The galaxy bispectrum directly probes the non-linear gravitational evolution of large-scale structure (LSS) and can break parameter degeneracies that remain in power-spectrum analy…
DESI DR2 Results IV: Alcock-Paczyński Measurements from the Lyman Alpha Forest and Cosmological Constraints
DESI Collaboration, A. G. Adame, J. Aguilar +152
We present Alcock-Paczyński (AP) measurements from the full shape of Lyman- (Ly) forest correlation functions measured from the second data release (DR2) of the Dark Energy S…
CMBComp: A Simple and Accurate Compressed CMB Likelihood for Dark Energy, Curvature, and Massive Neutrinos
Amogh Srivastav, Prakhar Bansal, Dragan Huterer
We present CMBComp, a compact and accurate compressed cosmic microwave background (CMB) likelihood that captures the dominant geometric information of the full CMB likelihood deriv…
Implications of SARAS3 data for Coulomb-like interacting dark matter
Shikhar Mittal, Prakhar Bansal, Harry Bevins +1
The 21-cm signal from cosmic dawn is a potentially sensitive probe of interactions between dark matter (DM) and baryons. We investigate the implications of the SARAS3 non-detection…
On the Difficulties with Late-Time Solutions for the Hubble Tension
Prakhar Bansal, Dragan Huterer
We explore the notion that cosmological models that modify the late-time expansion history cannot simultaneously fit the SH0ES collaboration's measurements of the Hubble constant,…
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 (…
Expansion-history preferences of DESI DR2 and external data
Prakhar Bansal, Dragan Huterer
We explore the origin of the preference of DESI DR2 baryon acoustic oscillation (BAO) measurements and external data from cosmic microwave background (CMB) and type Ia supernovae (…
