Recovering the characteristic halo mass of rare populations from clustering: a benchmark using the Millennium Simulation
Amrita Banerjee, Darren Croton
We measure how accurately the characteristic halo mass of a rare, massive population can be recovered from clustering alone, using dark matter haloes in the Millennium simulation,…

Clustering and physical properties of AGN and Star-Forming Galaxies at fixed stellar mass: does assembly bias have a role in AGN activity?
Amrita Banerjee, Biswajit Pandey, Anindita Nandi
We analyze a volume-limited sample from the Sloan Digital Sky Survey (SDSS) to compare the spatial clustering and physical properties of active galactic nuclei (AGN) and star-formi…

Ruling out Strongly Interacting Dark Matter-Dark Radiation Models from Joint Observations of Cosmic Microwave Background and Quasar Absorption Spectra
Atrideb Chatterjee, Sourav Mitra, Amrita Banerjee
The cold dark matter (CDM) paradigm provides a remarkably good description of the Universe's large-scale structure. However, some discrepancies exist between its predictions and ob…
