The DESI Experiment Part II: Instrument Design
DESI Collaboration, Amir Aghamousa, Jessica Aguilar +290
DESI (Dark Energy Spectropic Instrument) is a Stage IV ground-based dark energy experiment that will study baryon acoustic oscillations and the growth of structure through redshift…
The DESI Experiment Part I: Science,Targeting, and Survey Design
DESI Collaboration, Amir Aghamousa, Jessica Aguilar +290
DESI (Dark Energy Spectroscopic Instrument) is a Stage IV ground-based dark energy experiment that will study baryon acoustic oscillations (BAO) and the growth of structure through…
Consistency of the Planck CMB data and CDM cosmology
Arman Shafieloo, Dhiraj Kumar Hazra
We test the consistency between Planck temperature and polarization power spectra and the concordance model of Cold Dark Matter cosmology (CDM) within the framework of Cross…
Metastable Dark Energy with Radioactive-like Decay
Arman Shafieloo, Dhiraj Kumar Hazra, Varun Sahni +1
We propose a new class of metastable dark energy (DE) phenomenological models in which the DE decay rate does not depend on external parameters such as the scale factor or the curv…
Growth of perturbations in nonlocal gravity with non-CDM background
Sohyun Park, Arman Shafieloo
We re-analyze the nonlocal gravity model of Deser and Woodard which was proposed to account for the current phase of cosmic acceleration. We show that the growth of perturbations p…
Model-independent test of the FLRW metric, the flatness of the Universe, and non-local measurement of
Benjamin L'Huillier, Arman Shafieloo
Using measurements of and from the Baryon Oscillation Spectroscopic Survey (BOSS) DR12 and luminosity distances from the Joint Lightcurve Analysis (JLA) co…
