Constraints on dark matter annihilation in dwarf spheroidal galaxies from low frequency radio observations
Arpan Kar, Sourav Mitra, Biswarup Mukhopadhyaya +2
We present the first observational limits on the predicted synchrotron signals from particle Dark Matter annihilation models in dwarf spheroidal galaxies at radio frequencies below…
Heavy dark matter particle annihilation in dwarf spheroidal galaxies: radio signals at the SKA telescope
Arpan Kar, Sourav Mitra, Biswarup Mukhopadhyaya +1
A weakly interacting dark matter candidate is difficult to detect at high-energy colliders like the LHC, if its mass is close to, or higher than a TeV. On the other hand, pair-anni…
Carleman estimate for an adjoint of a damped beam equation and an application to null controllability
Sourav Mitra
In this article we consider a control problem of a linear Euler-Bernoulli damped beam equation with potential in dimension one with periodic boundary conditions. We derive a new Ca…
First study of reionization in tilted flat and untilted non-flat dynamical dark energy inflation models
Sourav Mitra, Chan-Gyung Park, Tirthankar Roy Choudhury +1
We examine the effects of dark energy dynamics and spatial curvature on cosmic reionization by studying reionization in tilted spatially-flat and untilted non-flat XCDM and CDM…
