Searching for systematics in SNIa and galaxy cluster data using the cosmic duality relation
Arman Shafieloo, Subhabrata Majumdar, Varun Sahni +1
We compare two different probes of the expansion history of the universe, namely, luminosity distances from type Ia supernovae and angular diameter distances from galaxy clusters,…
AGN feedback and entropy injection in galaxy cluster cores
Anya Chaudhuri, Subhabrata Majumdar, Biman B. Nath
The non-gravitational energy feedback is of crucial importance in modeling/simulating clusters to be used as cosmological probes. AGNs are, arguably, of primary importance in injec…
Cosmology with the largest galaxy cluster surveys: Going beyond Fisher matrix forecasts
Satej Khedekar, Subhabrata Majumdar
We make the first detailed MCMC likelihood study of cosmological constraints that are expected from some of the largest, ongoing and proposed, cluster surveys in different wave-ban…
Deriving the velocity distribution of Galactic Dark Matter particles from rotation curve data
Pijushpani Bhattacharjee, Soumini Chaudhury, Susmita Kundu +1
The velocity distribution function (VDF) of the hypothetical Weakly Interacting Massive Particles (WIMPs), currently the most favored candidate for the Dark Matter (DM) in the Gala…
Energy Deposition Profiles and Entropy in Galaxy Clusters
Anya Chaudhuri, Biman B. Nath, Subhabrata Majumdar
We report the results of our study of fractional entropy enhancement in the intra-cluster medium (ICM) of the clusters from the representative XMM-Newton cluster structure survey (…
