Density-split analyses of the pairwise kinetic Sunyaev-Zeldovich effect
Finn A. Roper, Aritra K. Gon, Yan-Chuan Cai +1
We consider the dependence of the kinetic Sunyaev-Zeldovich (kSZ) effect on the environments of foreground cosmological structures. Standard pairwise kSZ estimators exploit the fac…
Turning dispersion into signal: density-split analyses of pairwise velocities
Aritra Kumar Gon, Yan-Chuan Cai
Pairwise velocities of the large-scale structure encode valuable information about the growth of structure. They can be observed indirectly through redshift-space distortions and t…
Estimators for the cross-pairwise kSZ effect: forecasts for the dark energy and modified gravity parameters with Simons Observatory and CMB-S4
Aritra Kumar Gon, Rishi Khatri
We present and study a new cross-pairwise estimator to extract the kinetic Sunyaev Zeldovich (kSZ) signal from galaxy clusters. The existing pairwise kSZ method involves pairing cl…
The pairwise and cross-pairwise y-type polarised kinetic Sunyaev Zeldovich effect from transverse velocity of galaxy clusters
Aritra Kumar Gon, Rishi Khatri
We develop a new theoretical framework for studying the pairwise and cross-pairwise polarised kinetic Sunyaev Zeldovich (pkSZ) effect arising from the transverse peculiar velocity…
E and B modes of the CMB y-type distortions: polarised kinetic Sunyaev-Zeldovich effect from the reionisation and post-reionisation eras
Aritra Kumar Gon, Rishi Khatri
We study the E and B mode polarisation of the cosmic microwave background (CMB) originating from the transverse peculiar velocity of free electrons, at second order in perturbation…
Duality in a hyperbolic interaction model integrable even in a strong confinement: Multi-soliton solutions and field theory
Aritra Kumar Gon, Manas Kulkarni
Models that remain integrable even in confining potentials are extremely rare and almost non-existent. Here, we consider a one-dimensional hyperbolic interaction model, which we ca…
