Nonthermal warm dark matter limits from small-scale structure

Banerjee, Arka; Das, Subinoy; Maharana, Anshuman; Nadler, Ethan O.; Sharma, Ravi Kumar (American Physical Society, 2023-08-15)

We present small-scale structure constraints on sterile dark matter produced from a heavy mediator particle, inspired by models of moduli decay. Dark matter particles produced through this mechanism can contribute to the ...
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 ...
