The Completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: a multi-tracer analysis in Fourier space for measuring the cosmic structure growth and expansion rate
Gong-Bo Zhao, Yuting Wang, Atsushi Taruya +23
We perform a joint BAO and RSD analysis using the eBOSS DR16 LRG and ELG samples in the redshift range of , and detect a RSD signal from the cross power spectrum at…
A non-parametric consistency test of the CDM model with Planck CMB data
Amir Aghamousa, Jan Hamann, Arman Shafieloo
Non-parametric reconstruction methods, such as Gaussian process (GP) regression, provide a model-independent way of estimating an underlying function and its uncertainty from noisy…
Search for a direction in the forest of Lyman-
Dhiraj Kumar Hazra, Arman Shafieloo
We report the first test of isotropy of the Universe in the matter dominated epoch using the Lyman- forest data from the high redshift quasars () from SDSS-III BOSS-DR9 dat…
Nonparametric test of consistency between cosmological models and multiband CMB measurements
Amir Aghamousa, Arman Shafieloo
We present a novel approach to test the consistency of the cosmological models with multiband CMB data using a nonparametric approach. In our analysis we calibrate the REACT (Risk…
Confronting the concordance model of cosmology with Planck data
Dhiraj Kumar Hazra, Arman Shafieloo
We confront the concordance (standard) model of cosmology, the spatially flat CDM Universe with power-law form of the primordial spectrum with Planck CMB angular power spectrum…
ISW effect as probe of features in the expansion history of the Universe
Santanu Das, Arman Shafieloo, Tarun Souradeep
In this paper, using and implementing a new line of sight CMB code, called CMBAns [1], that allows us to modify H(z) for any given feature at any redshift we study the effect of ch…
