Signatures of Light Massive Relics on non-linear structure formation

Banerjee, Arka; Das, Subinoy; Maharana, Anshuman; Sharma, R. K (Oxford University Press on behalf of Royal Astronomical Society, 2022-10)

Cosmologies with Light Massive Relics (LiMRs) as a subdominant component of the dark sector are well-motivated from a particle physics perspective, and can also have implications for the σ8 tension between early and late ...
Small scale clustering of late forming dark matter

Agarwal, S; Corasaniti, P.-S; Das, Subinoy; Rasera, Y (The American Physical Society, 2015-09-15)

We perform a study of the nonlinear clustering of matter in the late-forming dark matter (LFDM) scenario in which dark matter results from the transition of a nonminimally coupled scalar field from radiation to collisionless ...
Static structure of chameleon dark matter as an explanation of dwarf spheroidal galaxy cores

Das, Subinoy; Prolay Krishna Chanda (The American Physical Society, 2017-04)

We propose a novel mechanism that explains the cored dark matter density profile in recently observed dark matter rich dwarf spheroidal galaxies. In our scenario, dark matter particle mass decreases gradually as a function ...
