Peering Beyond the Veil of Last Scattering: A View of the Universe with CMB Spectral Distortions
Bryce Cyr, Nabila Aghanim, Ethan Baker +37
The frequency spectrum of the cosmic microwave background is the most precise blackbody ever measured in nature, with deviations constrained at the level of almost one part per mil…
Signatures of composite dark matter in the Cosmic Microwave Background spectral distortions
Anoma Ganguly, Rishi Khatri, Tuhin S. Roy
We compute the spectral distortions of the Cosmic Microwave Background (CMB) created by an exotic process that extracts or injects photons of a particular frequency into the CMB. S…
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…
Inferences from surface brightness fluctuations of Zwicky 3146 via the Sunyaev-Zeldovich effect and X-ray observations
Charles E. Romero, Massimo Gaspari, Gerrit Schellenberger +16
The galaxy cluster Zwicky 3146 is a sloshing cool core cluster at that in SZ imaging does not appear to exhibit significant pressure substructure in the intracluster me…
EDGES of the dark forest: A new absorption window into the composite dark matter and large scale structure
Anoma Ganguly, Rishi Khatri, Tuhin S. Roy
We propose a new method to hunt for dark matter using dark forest/absorption features across the whole electromagnetic spectrum from radio to gamma rays, especially in the bands wh…
