The Completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: measurement of the BAO and growth rate of structure of the emission line galaxy sample from the anisotropic power spectrum between redshift 0.6 and 1.1
Arnaud de Mattia, Vanina Ruhlmann-Kleider, Anand Raichoor +33
We analyse the large-scale clustering in Fourier space of emission line galaxies (ELG) from the Data Release 16 of the Sloan Digital Sky Survey IV extended Baryon Oscillation Spect…
The galaxy power spectrum from TGSS ADR1 and the effect of flux calibration systematics
Prabhakar Tiwari, Shamik Ghosh, Pankaj Jain
We explore the large to moderate scale anisotropy in distant radio sources using the TGSS ADR1 catalog. We use different measures, i.e. number counts, sky brightness and flux per s…
Weak Lensing Effect on CMB in the Presence of a Dipole Anisotropy
Abhineet Agarwal, Naveen K. Singh, Pankaj Jain +1
We investigate weak lensing effect on cosmic microwave background (CMB) in the presence of dipole anisotropy. The approach of flat-sky approximation is considered. We determine the…
Large angular scale multipoles at redshift ~0.8
Prabhakar Tiwari, Pavan K. Aluri
We prepare the full sky radio galaxy map () using the north NVSS and south SUMSS galaxy catalogs and study the large scale multipoles anomalies. These galaxies are…
Evidence of isotropy at large-scale from polarizations of radio sources
Prabhakar Tiwari, Pankaj Jain
We test the isotropy of radio polarization angle orientations with a robust and reliable dual frequency polarimetric survey of active galactic nuclei (AGN). We find that the polari…
New limit on pseudoscalar-photon mixing from WMAP Observations
Prabhakar Tiwari
The pseudoscalar-photon mixing in presence of large scale magnetic field induces polarization in light from distant cosmological sources. We study the effect of these pseudoscalars…
