Probing freeze-in dark matter using Bose-Einstein condensate in neutron star
Deep Ghosh, Anirban Das
Neutron star (NS) is one of the most promising astrophysical targets to probe non-gravitational interaction of dark matter (DM) with visible matter. Their compactness makes them an…
Mass varying dark matter and its cosmological signature
Anirban Das, Subinoy Das, Shiv K. Sethi
Nontrivial dark sector physics continues to be an interesting avenue in our quest to the nature of dark matter. In this paper, we study the cosmological signatures of mass-varying…
The magnificent ACT of flavor-specific neutrino self-interaction
Anirban Das, Subhajit Ghosh
We revisit the cosmology of neutrino self-interaction and use the latest cosmic microwave background data from the Atacama Cosmology Telescope (ACT) and the Planck experiment to co…
Neutrino secret self-interactions: a booster shot for the cosmic neutrino background
Anirban Das, Yuber F. Perez-Gonzalez, Manibrata Sen
Neutrinos might interact among themselves through forces that have so far remained hidden. Throughout the history of the Universe, such \emph{secret} interactions could lead to sca…
Neutrino Self-Interactions: A White Paper
Jeffrey M. Berryman, Nikita Blinov, Vedran Brdar +31
Neutrinos are the Standard Model (SM) particles which we understand the least, often due to how weakly they interact with the other SM particles. Beyond this, very little is known…
