Quantifying the redshift space distortion of the bispectrum III : Detection prospects of the multipole moments
Arindam Mazumdar, Debanjan Sarkar, Somnath Bharadwaj
The redshift space anisotropy of the bispectrum is generally quantified using multipole moments. The possibility of measuring these multipoles in any survey depends on the level of…
Cosmology Intertwined: A Review of the Particle Physics, Astrophysics, and Cosmology Associated with the Cosmological Tensions and Anomalies
Elcio Abdalla, Guillermo Franco Abellán, Amin Aboubrahim +200
In this paper we will list a few important goals that need to be addressed in the next decade, also taking into account the current discordances between the different cosmological…
Evidence of dark energy in different cosmological observations
Arindam Mazumdar, Subhendra Mohanty, Priyank Parashari
The idea of a negative-pressure dark energy component in the Universe which causes an accelerated expansion in the late Universe has deep implications in models of field theory and…
A fast estimator for quantifying the shape dependence of the 3D bispectrum
Abinash Kumar Shaw, Somnath Bharadwaj, Debanjan Sarkar +3
The dependence of the bispectrum on the size and shape of the triangle contains a wealth of cosmological information. Here we consider a triangle parameterization which allows us t…
Redshifted 21-cm Bispectrum I: Impact of the Redshift Space Distortions on the Signal from the Epoch of Reionization
Suman Majumdar, Mohd Kamran, Jonathan R. Pritchard +4
The bispectrum can quantify the non-Gussianity present in the redshifted 21-cm signal produced by the neutral hydrogen (HI) during the epoch of reionization (EoR). Motivated by thi…
Quantifying the Redshift Space Distortion of the Bispectrum II: Induced Non-Gaussianity at Second Order Perturbation
Arindam Mazumdar, Somnath Bharadwaj, Debanjan Sarkar
The anisotrpy of the redshift space bispectrum , which contains a wealth of cosmological information, is completely quantified using mu…
