Concealing Dirac neutrinos from cosmic microwave background
Anirban Biswas, Dilip Kumar Ghosh, Dibyendu Nanda
The existence of prolonged radiation domination prior to the Big Bang Nucleosynthesis (BBN), starting just after the inflationary epoch, is not yet established unanimously. If inst…
Improved White Dwarves Constraints on Inelastic Dark Matter and Left-Right Symmetric Models
Anirban Biswas, Arpan Kar, Hyomin Kim +2
WIMPs can be captured in compact stars such as white dwarves (WDs) leading to an increase in the star luminosity through their annihilation process. We show that when the WIMP inte…
Freeze-in Dark Matter via Light Dirac Neutrino Portal
Anirban Biswas, Debasish Borah, Nayan Das +1
We propose a scenario where dark matter (DM) can be generated non-thermally due to the presence of a light Dirac neutrino portal between the standard model (SM) and dark sector par…
MOBSTER -- VI. The crucial influence of rotation on the radio magnetospheres of hot stars
M. E. Shultz, S. P. Owocki, A. ud-Doula +13
Numerous magnetic hot stars exhibit gyrosynchrotron radio emission. The source electrons were previously thought to be accelerated to relativistic velocities in the current sheet f…
