Baryonic feedback and intrinsic alignments in profile: a frequentist view of DES Y3 cosmic shear
Anoma Ganguly, Elisabeth Krause, Tanvi Karwal +1
Current cosmic shear surveys primarily constrain and , while most other model parameters remain dominated by priors. Consequently, marginal posteriors are vulne…
Probing multi-state dark matter via optical absorption lines in DESI spectra
Anoma Ganguly, Shadab Alam
We search for dark matter through absorption lines imprinted on the spectra of background sources whose sightlines pass through foreground dark matter halos. Such a line is a gener…
Direct shear kSZ correlation: controlling baryons without modeling galaxies
Anoma Ganguly, Emmanuel Schaan, Elisabeth Krause +1
Baryonic feedback redistributes gas within and around dark matter haloes, suppressing the small-scale matter power spectrum at a level that is now the leading systematic for upcomi…
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…
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…
